It also adds <templates> + * to be used as cells in toolbars, auto-validation using the <validation> + * flag, attribute cycling using <cycleAttributeValues>, higher-level events + * such as <root>, and backend integration using <urlPost>, <urlImage>, + * <urlInit>, <urlNotify> and <urlPoll>. + * + * Actions: + * + * Actions are functions stored in the <actions> array under their names. The + * functions take the <mxEditor> as the first, and an optional <mxCell> as the + * second argument and are invoked using <execute>. Any additional arguments + * passed to execute are passed on to the action as-is. + * + * A list of built-in actions is available in the <addActions> description. + * + * Read/write Diagrams: + * + * To read a diagram from an XML string, for example from a textfield within the + * page, the following code is used: + * + * (code) + * var doc = mxUtils.parseXML(xmlString); + * var node = doc.documentElement; + * editor.readGraphModel(node); + * (end) + * + * For reading a diagram from a remote location, use the <open> method. + * + * To save diagrams in XML on a server, you can set the <urlPost> variable. + * This variable will be used in <getUrlPost> to construct a URL for the post + * request that is issued in the <save> method. The post request contains the + * XML representation of the diagram as returned by <writeGraphModel> in the + * xml parameter. + * + * On the server side, the post request is processed using standard + * technologies such as Java Servlets, CGI, .NET or ASP. + * + * Here are some examples of processing a post request in various languages. + * + * - Java: URLDecoder.decode(request.getParameter("xml"), "UTF-8").replace("\n", "
") + * + * Note that the linefeeds should only be replaced if the XML is + * processed in Java, for example when creating an image, but not + * if the XML is passed back to the client-side. + * + * - .NET: HttpUtility.UrlDecode(context.Request.Params["xml"]) + * - PHP: urldecode($_POST["xml"]) + * + * Creating images: + * + * A backend (Java, PHP or C#) is required for creating images. The + * distribution contains an example for each backend (ImageHandler.java, + * ImageHandler.cs and graph.php). More information about using a backend + * to create images can be found in the readme.html files. Note that the + * preview is implemented using VML/SVG in the browser and does not require + * a backend. The backend is only required to creates images (bitmaps). + * + * Special characters: + * + * Note There are five characters that should always appear in XML content as + * escapes, so that they do not interact with the syntax of the markup. These + * are part of the language for all documents based on XML and for HTML. + * + * - < (<) + * - > (>) + * - & (&) + * - " (") + * - ' (') + * + * Although it is part of the XML language, ' is not defined in HTML. + * For this reason the XHTML specification recommends instead the use of + * ' if text may be passed to a HTML user agent. + * + * If you are having problems with special characters on the server-side then + * you may want to try the <escapePostData> flag. + * + * For converting decimal escape sequences inside strings, a user has provided + * us with the following function: + * + * (code) + * function html2js(text) + * { + * var entitySearch = /&#[0-9]+;/; + * var entity; + * + * while (entity = entitySearch.exec(text)) + * { + * var charCode = entity[0].substring(2, entity[0].length -1); + * text = text.substring(0, entity.index) + * + String.fromCharCode(charCode) + * + text.substring(entity.index + entity[0].length); + * } + * + * return text; + * } + * (end) + * + * Otherwise try using hex escape sequences and the built-in unescape function + * for converting such strings. + * + * Local Files: + * + * For saving and opening local files, no standardized method exists that + * works across all browsers. The recommended way of dealing with local files + * is to create a backend that streams the XML data back to the browser (echo) + * as an attachment so that a Save-dialog is displayed on the client-side and + * the file can be saved to the local disk. + * + * For example, in PHP the code that does this looks as follows. + * + * (code) + * $xml = stripslashes($_POST["xml"]); + * header("Content-Disposition: attachment; filename=\"diagram.xml\""); + * echo($xml); + * (end) + * + * To open a local file, the file should be uploaded via a form in the browser + * and then opened from the server in the editor. + * + * Cell Properties: + * + * The properties displayed in the properties dialog are the attributes and + * values of the cell's user object, which is an XML node. The XML node is + * defined in the templates section of the config file. + * + * The templates are stored in <mxEditor.templates> and contain cells which + * are cloned at insertion time to create new vertices by use of drag and + * drop from the toolbar. Each entry in the toolbar for adding a new vertex + * must refer to an existing template. + * + * In the following example, the task node is a business object and only the + * mxCell node and its mxGeometry child contain graph information: + * + * (code) + * <Task label="Task" description=""> + * <mxCell vertex="true"> + * <mxGeometry as="geometry" width="72" height="32"/> + * </mxCell> + * </Task> + * (end) + * + * The idea is that the XML representation is inverse from the in-memory + * representation: The outer XML node is the user object and the inner node is + * the cell. This means the user object of the cell is the Task node with no + * children for the above example: + * + * (code) + * <Task label="Task" description=""/> + * (end) + * + * The Task node can have any tag name, attributes and child nodes. The + * <mxCodec> will use the XML hierarchy as the user object, while removing the + * "known annotations", such as the mxCell node. At save-time the cell data + * will be "merged" back into the user object. The user object is only modified + * via the properties dialog during the lifecycle of the cell. + * + * In the default implementation of <createProperties>, the user object's + * attributes are put into a form for editing. Attributes are changed using + * the <mxCellAttributeChange> action in the model. The dialog can be replaced + * by overriding the <createProperties> hook or by replacing the showProperties + * action in <actions>. Alternatively, the entry in the config file's popupmenu + * section can be modified to invoke a different action. + * + * If you want to displey the properties dialog on a doubleclick, you can set + * <mxEditor.dblClickAction> to showProperties as follows: + * + * (code) + * editor.dblClickAction = 'showProperties'; + * (end) + * + * Popupmenu and Toolbar: + * + * The toolbar and popupmenu are typically configured using the respective + * sections in the config file, that is, the popupmenu is defined as follows: + * + * (code) + * <mxEditor> + * <mxDefaultPopupMenu as="popupHandler"> + * <add as="cut" action="cut" icon="images/cut.gif"/> + * ... + * (end) + * + * New entries can be added to the toolbar by inserting an add-node into the + * above configuration. Existing entries may be removed and changed by + * modifying or removing the respective entries in the configuration. + * The configuration is read by the <mxDefaultPopupMenuCodec>, the format of the + * configuration is explained in <mxDefaultPopupMenu.decode>. + * + * The toolbar is defined in the mxDefaultToolbar section. Items can be added + * and removed in this section. + * + * (code) + * <mxEditor> + * <mxDefaultToolbar> + * <add as="save" action="save" icon="images/save.gif"/> + * <add as="Swimlane" template="swimlane" icon="images/swimlane.gif"/> + * ... + * (end) + * + * The format of the configuration is described in + * <mxDefaultToolbarCodec.decode>. + * + * Ids: + * + * For the IDs, there is an implicit behaviour in <mxCodec>: It moves the Id + * from the cell to the user object at encoding time and vice versa at decoding + * time. For example, if the Task node from above has an id attribute, then + * the <mxCell.id> of the corresponding cell will have this value. If there + * is no Id collision in the model, then the cell may be retrieved using this + * Id with the <mxGraphModel.getCell> function. If there is a collision, a new + * Id will be created for the cell using <mxGraphModel.createId>. At encoding + * time, this new Id will replace the value previously stored under the id + * attribute in the Task node. + * + * See <mxEditorCodec>, <mxDefaultToolbarCodec> and <mxDefaultPopupMenuCodec> + * for information about configuring the editor and user interface. + * + * Programmatically inserting cells: + * + * For inserting a new cell, say, by clicking a button in the document, + * the following code can be used. This requires an reference to the editor. + * + * (code) + * var userObject = new Object(); + * var parent = editor.graph.getDefaultParent(); + * var model = editor.graph.model; + * model.beginUpdate(); + * try + * { + * editor.graph.insertVertex(parent, null, userObject, 20, 20, 80, 30); + * } + * finally + * { + * model.endUpdate(); + * } + * (end) + * + * If a template cell from the config file should be inserted, then a clone + * of the template can be created as follows. The clone is then inserted using + * the add function instead of addVertex. + * + * (code) + * var template = editor.templates['task']; + * var clone = editor.graph.model.cloneCell(template); + * (end) + * + * Resources: + * + * resources/editor - Language resources for mxEditor + * + * Callback: onInit + * + * Called from within the constructor. In the callback, + * "this" refers to the editor instance. + * + * Cookie: mxgraph=seen + * + * Set when the editor is started. Never expires. Use + * <resetFirstTime> to reset this cookie.

The constant is a value between 0 and 1 that specifies the + * amount of the width and height around the center to be used for the hotspot + * of a cell and its default value is 0.5. In addition, + * <mxConstants.MIN_HOTSPOT_SIZE> defines the minimum number of pixels for the + * width and height of the hotspot. + * + * This solution, while standards compliant, may be somewhat confusing because + * there is no visual indicator for the hotspot and the highlight is seen to + * switch on and off while the mouse is being moved in and out. Furthermore, + * this paradigm does not allow to create different connections depending on + * the highlighted hotspot as there is only one hotspot per cell and it + * normally does not allow cells to be moved and connected at the same time as + * there is no clear indication of the connectable area of the cell. + * + * To come across these issues, the handle has an additional <createIcons> hook + * with a default implementation that allows to create one icon to be used to + * trigger new connections. If this icon is specified, then new connections can + * only be created if the image is clicked while the cell is being highlighted. + * The <createIcons> hook may be overridden to create more than one + * <mxImageShape> for creating new connections, but the default implementation + * supports one image and is used as follows: + * + * In order to display the "connect image" whenever the mouse is over the cell, + * an DEFAULT_HOTSPOT of 1 should be used: + * + * (code) + * mxConstants.DEFAULT_HOTSPOT = 1; + * (end) + * + * In order to avoid confusion with the highlighting, the highlight color + * should not be used with a connect image: + * + * (code) + * mxConstants.HIGHLIGHT_COLOR = null; + * (end) + * + * To install the image, the connectImage field of the mxConnectionHandler must + * be assigned a new <mxImage> instance: + * + * (code) + * mxConnectionHandler.prototype.connectImage = new mxImage('images/green-dot.gif', 14, 14); + * (end) + * + * This will use the green-dot.gif with a width and height of 14 pixels as the + * image to trigger new connections. In createIcons the icon field of the + * handler will be set in order to remember the icon that has been clicked for + * creating the new connection. This field will be available under selectedIcon + * in the connect method, which may be overridden to take the icon that + * triggered the new connection into account. This is useful if more than one + * icon may be used to create a connection. + * + * Group: Events + * + * Event: mxEvent.START + * + * Fires when a new connection is being created by the user. The <code>state</code> + * property contains the state of the source cell. + * + * Event: mxEvent.CONNECT + * + * Fires between begin- and endUpdate in <connect>. The <code>cell</code> + * property contains the inserted edge, the <code>event</code> and <code>target</code> + * properties contain the respective arguments that were passed to <connect> (where + * target corresponds to the dropTarget argument). + * + * Note that the target is the cell under the mouse where the mouse button was released. + * Depending on the logic in the handler, this doesn't necessarily have to be the target + * of the inserted edge. To print the source, target or any optional ports IDs that the + * edge is connected to, the following code can be used.

The top-level <mxClient> + class includes (or dynamically imports) everything else. The current version + is stored in <mxClient.VERSION>. + + The *editor* package provides the classes required to implement a diagram + editor. The main class in this package is <mxEditor>. + + The *view* and *model* packages implement the graph component, represented + by <mxGraph>. It refers to a <mxGraphModel> which contains <mxCell>s and + caches the state of the cells in a <mxGraphView>. The cells are painted + using a <mxCellRenderer> based on the appearance defined in <mxStylesheet>. + Undo history is implemented in <mxUndoManager>. To display an icon on the + graph, <mxCellOverlay> may be used. Validation rules are defined with + <mxMultiplicity>. + + The *handler*, *layout* and *shape* packages contain event listeners, + layout algorithms and shapes, respectively. The graph event listeners + include <mxRubberband> for rubberband selection, <mxTooltipHandler> + for tooltips and <mxGraphHandler> for basic cell modifications. + <mxCompactTreeLayout> implements a tree layout algorithm, and the + shape package provides various shapes, which are subclasses of + <mxShape>. + + The *util* package provides utility classes including <mxClipboard> for + copy-paste, <mxDatatransfer> for drag-and-drop, <mxConstants> for keys and + values of stylesheets, <mxEvent> and <mxUtils> for cross-browser + event-handling and general purpose functions, <mxResources> for + internationalization and <mxLog> for console output. + + The *io* package implements a generic <mxObjectCodec> for turning + JavaScript objects into XML. The main class is <mxCodec>. + <mxCodecRegistry> is the global registry for custom codecs. + +Events: + + There are three different types of events, namely native DOM events, + <mxEventObjects> which are fired in an <mxEventSource>, and <mxMouseEvents> + which are fired in <mxGraph>. + + Some helper methods for handling native events are provided in <mxEvent>. It + also takes care of resolving cycles between DOM nodes and JavaScript event + handlers, which can lead to memory leaks in IE6. + + Most custom events in mxGraph are implemented using <mxEventSource>. Its + listeners are functions that take a sender and <mxEventObject>. Additionally, + the <mxGraph> class fires special <mxMouseEvents> which are handled using + mouse listeners, which are objects that provide a mousedown, mousemove and + mouseup method. + + Events in <mxEventSource> are fired using <mxEventSource.fireEvent>. + Listeners are added and removed using <mxEventSource.addListener> and + <mxEventSource.removeListener>. <mxMouseEvents> in <mxGraph> are fired using + <mxGraph.fireMouseEvent>.

Use GIF images (256 color palette) in HTML + elements (such as the toolbar and context menu), and PNG images (24 bit) for + all images which appear inside the graph component. + + - For PNG images inside HTML elements, Internet Explorer will ignore any + transparency information. + - For GIF images inside the graph, Firefox on the Mac will display strange + colors. Furthermore, only the first image for animated GIFs is displayed + on the Mac. + + For faster image rendering during application runtime, images can be + prefetched using the following code: + + (code) + var image = new Image(); + image.src = url_to_image; + (end) + +Deployment: + + The client is added to the page using the following script tag inside the + head of a document: + + (code) + <script type="text/javascript" src="js/mxClient.js"></script> + (end) + + The deployment version of the mxClient.js file contains all required code + in a single file. For deployment, the complete javascript/src directory is + required. + +Source Code: + + If you are a source code customer and you wish to develop using the + full source code, the commented source code is shipped in the + javascript/devel/source.zip file. It contains one file for each class + in mxGraph. To use the source code the source.zip file must be + uncompressed and the mxClient.js URL in the HTML page must be changed + to reference the uncompressed mxClient.js from the source.zip file. + +Compression: + + When using Apache2 with mod_deflate, you can use the following directive + in src/js/.htaccess to speedup the loading of the JavaScript sources: + + (code) + SetOutputFilter DEFLATE + (end) + +Classes: + + There are two types of "classes" in mxGraph: classes and singletons (where + only one instance exists). Singletons are mapped to global objects where the + variable name equals the classname. For example mxConstants is an object with + all the constants defined as object fields. Normal classes are mapped to a + constructor function and a prototype which defines the instance fields and + methods. For example, <mxEditor> is a function and mxEditor.prototype is the + prototype for the object that the mxEditor function creates. The mx prefix is + a convention that is used for all classes in the mxGraph package to avoid + conflicts with other objects in the global namespace. + +Subclassing: + + For subclassing, the superclass must provide a constructor that is either + parameterless or handles an invocation with no arguments. Furthermore, the + special constructor field must be redefined after extending the prototype. + For example, the superclass of mxEditor is <mxEventSource>. This is + represented in JavaScript by first "inheriting" all fields and methods from + the superclass by assigning the prototype to an instance of the superclass, + eg. mxEditor.prototype = new mxEventSource() and redefining the constructor + field using mxEditor.prototype.constructor = mxEditor. The latter rule is + applied so that the type of an object can be retrieved via the name of it’s + constructor using mxUtils.getFunctionName(obj.constructor). + +Constructor: + + For subclassing in mxGraph, the same scheme should be applied. For example, + for subclassing the <mxGraph> class, first a constructor must be defined for + the new class. The constructor calls the super constructor with any arguments + that it may have using the call function on the mxGraph function object, + passing along explitely each argument: + + (code) + function MyGraph(container) + { + mxGraph.call(this, container); + } + (end) + + The prototype of MyGraph inherits from mxGraph as follows. As usual, the + constructor is redefined after extending the superclass: + + (code) + MyGraph.prototype = new mxGraph(); + MyGraph.prototype.constructor = MyGraph; + (end) + + You may want to define the codec associated for the class after the above + code. This code will be executed at class loading time and makes sure the + same codec is used to encode instances of mxGraph and MyGraph. + + (code) + var codec = mxCodecRegistry.getCodec(mxGraph); + codec.template = new MyGraph(); + mxCodecRegistry.register(codec); + (end) + +Functions: + + In the prototype for MyGraph, functions of mxGraph can then be extended as + follows. + + (code) + MyGraph.prototype.isCellSelectable = function(cell) + { + var selectable = mxGraph.prototype.isSelectable.apply(this, arguments); + + var geo = this.model.getGeometry(cell); + return selectable && (geo == null || !geo.relative); + } + (end) + + The supercall in the first line is optional. It is done using the apply + function on the isSelectable function object of the mxGraph prototype, using + the special this and arguments variables as parameters. Calls to the + superclass function are only possible if the function is not replaced in the + superclass as follows, which is another way of “subclassing” in JavaScript. + + (code) + mxGraph.prototype.isCellSelectable = function(cell) + { + var geo = this.model.getGeometry(cell); + return selectable && + (geo == null || + !geo.relative); + } + (end) + + The above scheme is useful if a function definition needs to be replaced + completely. + + In order to add new functions and fields to the subclass, the following code + is used. The example below adds a new function to return the XML + representation of the graph model: + + (code) + MyGraph.prototype.getXml = function() + { + var enc = new mxCodec(); + return enc.encode(this.getModel()); + } + (end) + +Variables: + + Likewise, a new field is declared and defined as follows. + + (code) + MyGraph.prototype.myField = 'Hello, World!'; + (end) + + Note that the value assigned to myField is created only once, that is, all + instances of MyGraph share the same value. If you require instance-specific + values, then the field must be defined in the constructor instead. + + (code) + function MyGraph(container) + { + mxGraph.call(this, container); + + this.myField = new Array(); + } + (end) + + Finally, a new instance of MyGraph is created using the following code, where + container is a DOM node that acts as a container for the graph view: + + (code) + var graph = new MyGraph(container); + (end) diff --git a/src/js/io/mxCellCodec.js b/src/js/io/mxCellCodec.js new file mode 100644 index 0000000..cbcd651 --- /dev/null +++ b/src/js/io/mxCellCodec.js @@ -0,0 +1,170 @@ +/** + * $Id: mxCellCodec.js,v 1.22 2010-10-21 07:12:31 gaudenz Exp $ + * Copyright (c) 2006-2010, JGraph Ltd + */ +mxCodecRegistry.register(function() +{ + /** + * Class: mxCellCodec + * + * Codec for <mxCell>s.

The decoder also accepts the string true + * and false for boolean values. + * + * Objects: + * + * The above scheme is applied to all atomic fields, that is, to all non-object + * fields of an object. For object fields, a child node is created with a + * special attribute that contains the fieldname. This special attribute is + * called "as" and hence, as is a reserved word that should not be used for a + * fieldname. + * + * Consider the following example where foo is an object and bar is an atomic + * property of foo. + * + * (code) + * var obj = {foo: {bar: "Bar"}}; + * (end) + * + * This will be mapped to the following XML structure by mxObjectCodec. + * + * (code) + * <Object> + * <Object bar="Bar" as="foo"/> + * </Object> + * (end) + * + * In the above output, the inner Object node contains the as-attribute that + * specifies the fieldname in the enclosing object. That is, the field foo was + * mapped to a child node with an as-attribute that has the value foo. + * + * Arrays: + * + * Arrays are special objects that are either associative, in which case each + * key, value pair is treated like a field where the key is the fieldname, or + * they are a sequence of atomic values and objects, which is mapped to a + * sequence of child nodes. For object elements, the above scheme is applied + * without the use of the special as-attribute for creating each child. For + * atomic elements, a special add-node is created with the value stored in the + * value-attribute. + * + * For example, the following array contains one atomic value and one object + * with a field called bar. Furthermore it contains two associative entries + * called bar with an atomic value, and foo with an object value. + * + * (code) + * var obj = ["Bar", {bar: "Bar"}]; + * obj["bar"] = "Bar"; + * obj["foo"] = {bar: "Bar"}; + * (end) + * + * This array is represented by the following XML nodes. + * + * (code) + * <Array bar="Bar"> + * <add value="Bar"/> + * <Object bar="Bar"/> + * <Object bar="Bar" as="foo"/> + * </Array> + * (end) + * + * The Array node name is the name of the constructor. The additional + * as-attribute in the last child contains the key of the associative entry, + * whereas the second last child is part of the array sequence and does not + * have an as-attribute. + * + * References: + * + * Objects may be represented as child nodes or attributes with ID values, + * which are used to lookup the object in a table within <mxCodec>. The + * <isReference> function is in charge of deciding if a specific field should + * be encoded as a reference or not. Its default implementation returns true if + * the fieldname is in <idrefs>, an array of strings that is used to configure + * the <mxObjectCodec>. + * + * Using this approach, the mapping does not guarantee that the referenced + * object itself exists in the document. The fields that are encoded as + * references must be carefully chosen to make sure all referenced objects + * exist in the document, or may be resolved by some other means if necessary. + * + * For example, in the case of the graph model all cells are stored in a tree + * whose root is referenced by the model's root field. A tree is a structure + * that is well suited for an XML representation, however, the additional edges + * in the graph model have a reference to a source and target cell, which are + * also contained in the tree. To handle this case, the source and target cell + * of an edge are treated as references, whereas the children are treated as + * objects. Since all cells are contained in the tree and no edge references a + * source or target outside the tree, this setup makes sure all referenced + * objects are contained in the document. + * + * In the case of a tree structure we must further avoid infinite recursion by + * ignoring the parent reference of each child. This is done by returning true + * in <isExcluded>, whose default implementation uses the array of excluded + * fieldnames passed to the mxObjectCodec constructor. + * + * References are only used for cells in mxGraph. For defining other + * referencable object types, the codec must be able to work out the ID of an + * object. This is done by implementing <mxCodec.reference>. For decoding a + * reference, the XML node with the respective id-attribute is fetched from the + * document, decoded, and stored in a lookup table for later reference. For + * looking up external objects, <mxCodec.lookup> may be implemented. + * + * Expressions: + * + * For decoding JavaScript expressions, the add-node may be used with a text + * content that contains the JavaScript expression. For example, the following + * creates a field called foo in the enclosing object and assigns it the value + * of <mxConstants.ALIGN_LEFT>. + * + * (code) + * <Object> + * <add as="foo">mxConstants.ALIGN_LEFT</add> + * </Object> + * (end) + * + * The resulting object has a field called foo with the value "left". Its XML + * representation looks as follows. + * + * (code) + * <Object foo="left"/> + * (end) + * + * This means the expression is evaluated at decoding time and the result of + * the evaluation is stored in the respective field. Valid expressions are all + * JavaScript expressions, including function definitions, which are mapped to + * functions on the resulting object. + * + * Constructor: mxObjectCodec + * + * Constructs a new codec for the specified template object. + * The variables in the optional exclude array are ignored by + * the codec.

Note that the + * fill, stroke or fillstroke of the background is be the first statement + * of the foreground. This is because the content of the background node + * maybe used to not only render the shape itself, but also its shadow and + * other elements which do not require a fill, stroke or fillstroke. + * + * The shape uses a coordinate system with a width of 100 and a height of + * 100 by default. This can be changed by setting the w and h attribute of + * the shape element. The aspect attribute can be set to "variable" (default) + * or "fixed". If fixed is used, then the aspect which is defined via the w + * and h attribute is kept constant while the shape is scaled. + * + * The possible contents of the background and foreground elements are rect, + * ellipse, roundrect, text, image, include-shape or paths. A path element + * contains move, line, curve, quad, arc and close elements. The rect, ellipse + * and roundrect elements may be thought of as special path elements. All these + * path elements must be followed by either fill, stroke or fillstroke (note + * that text, image and include-shape or not path elements). + * + * The background element can be empty or contain at most one path element. It + * should not contain a text, image or include-shape element. If the background + * element is empty, then no shadow or glass effect will be rendered. If the + * background element is non-empty, then the corresponding fill, stroke or + * fillstroke should be the first element in the subsequent foreground element. + * + * The format of the XML is "a simplified HTML 5 Canvas". Each command changes + * the "current" state, so eg. a linecap, linejoin will be used for all + * subsequent line drawing, unless a save/restore appears, which saves/restores + * a state in a stack. + * + * The connections section contains the fixed connection points for a stencil. + * The perimeter attribute of the constraint element should have a value of 0 + * or 1 (default), where 1 (true) specifies that the given point should be + * projected into the perimeter of the given shape. + * + * The x- and y-coordinates are typically between 0 and 1 and define the + * location of the connection point relative to the width and height of the + * shape. + * + * The dashpattern directive sets the current dashpattern. The format for the + * pattern attribute is a space-separated sequence of numbers, eg. 5 5 5 5, + * that specifies the lengths of alternating dashes and spaces in dashed lines. + * The dashpattern should be used together with the dashed directive to + * enabled/disable the dashpattern. The default dashpattern is 3 3. + * + * The strokewidth attribute defines a fixed strokewidth for the shape. It + * can contain a numeric value or the keyword "inherit", which means that the + * strokeWidth from the cell's style will be used and muliplied with the shape's + * scale. If numeric values are used, those are multiplied with the minimum + * scale used to render the stencil inside the shape's bounds. + * + * Constructor: mxStencilShape + * + * Constructs a new generic shape by setting <desc> to the given XML node and + * invoking <parseDescription> and <parseConstraints>. + * + * Parameters: + * + * desc - XML node that contains the stencil description. + */ +function mxStencil(desc) +{ + this.desc = desc; + this.parseDescription(); + this.parseConstraints(); +}; + +/** + * Variable: desc + * + * Holds the XML node with the stencil description. + */ +mxStencil.prototype.desc = null; + +/** + * Variable: constraints + * + * Holds an array of <mxConnectionConstraints> as defined in the shape. + */ +mxStencil.prototype.constraints = null; + +/** + * Variable: aspect + * + * Holds the aspect of the shape.

This is the main class of the package. To activate + * panning and connections use <setPanning> and <setConnectable>. + * For rubberband selection you must create a new instance of + * <mxRubberband>. The following listeners are added to + * <mouseListeners> by default: + * + * - <tooltipHandler>: <mxTooltipHandler> that displays tooltips + * - <panningHandler>: <mxPanningHandler> for panning and popup menus + * - <connectionHandler>: <mxConnectionHandler> for creating connections + * - <graphHandler>: <mxGraphHandler> for moving and cloning cells + * + * These listeners will be called in the above order if they are enabled. + * + * Background Images: + * + * To display a background image, set the image, image width and + * image height using <setBackgroundImage>. If one of the + * above values has changed then the <view>'s <mxGraphView.validate> + * should be invoked. + * + * Cell Images: + * + * To use images in cells, a shape must be specified in the default + * vertex style (or any named style). Possible shapes are + * <mxConstants.SHAPE_IMAGE> and <mxConstants.SHAPE_LABEL>. + * The code to change the shape used in the default vertex style, + * the following code is used: + * + * (code) + * var style = graph.getStylesheet().getDefaultVertexStyle(); + * style[mxConstants.STYLE_SHAPE] = mxConstants.SHAPE_IMAGE; + * (end) + * + * For the default vertex style, the image to be displayed can be + * specified in a cell's style using the <mxConstants.STYLE_IMAGE> + * key and the image URL as a value, for example: + * + * (code) + * image=http://www.example.com/image.gif + * (end) + * + * For a named style, the the stylename must be the first element + * of the cell style: + * + * (code) + * stylename;image=http://www.example.com/image.gif + * (end) + * + * A cell style can have any number of key=value pairs added, divided + * by a semicolon as follows: + * + * (code) + * [stylename;|key=value;] + * (end) + * + * Labels: + * + * The cell labels are defined by <getLabel> which uses <convertValueToString> + * if <labelsVisible> is true. If a label must be rendered as HTML markup, then + * <isHtmlLabel> should return true for the respective cell. If all labels + * contain HTML markup, <htmlLabels> can be set to true. NOTE: Enabling HTML + * labels carries a possible security risk (see the section on security in + * the manual). + * + * If wrapping is needed for a label, then <isHtmlLabel> and <isWrapping> must + * return true for the cell whose label should be wrapped. See <isWrapping> for + * an example. + * + * If clipping is needed to keep the rendering of a HTML label inside the + * bounds of its vertex, then <isClipping> should return true for the + * respective cell. + * + * By default, edge labels are movable and vertex labels are fixed. This can be + * changed by setting <edgeLabelsMovable> and <vertexLabelsMovable>, or by + * overriding <isLabelMovable>. + * + * In-place Editing: + * + * In-place editing is started with a doubleclick or by typing F2. + * Programmatically, <edit> is used to check if the cell is editable + * (<isCellEditable>) and call <startEditingAtCell>, which invokes + * <mxCellEditor.startEditing>. The editor uses the value returned + * by <getEditingValue> as the editing value. + * + * After in-place editing, <labelChanged> is called, which invokes + * <mxGraphModel.setValue>, which in turn calls + * <mxGraphModel.valueForCellChanged> via <mxValueChange>. + * + * The event that triggers in-place editing is passed through to the + * <cellEditor>, which may take special actions depending on the type of the + * event or mouse location, and is also passed to <getEditingValue>. The event + * is then passed back to the event processing functions which can perform + * specific actions based on the trigger event. + * + * Tooltips: + * + * Tooltips are implemented by <getTooltip>, which calls <getTooltipForCell> + * if a cell is under the mousepointer. The default implementation checks if + * the cell has a getTooltip function and calls it if it exists. Hence, in order + * to provide custom tooltips, the cell must provide a getTooltip function, or + * one of the two above functions must be overridden. + * + * Typically, for custom cell tooltips, the latter function is overridden as + * follows: + * + * (code) + * graph.getTooltipForCell = function(cell) + * { + * var label = this.convertValueToString(cell); + * return 'Tooltip for '+label; + * } + * (end) + * + * When using a config file, the function is overridden in the mxGraph section + * using the following entry: + * + * (code) + * <add as="getTooltipForCell"><![CDATA[ + * function(cell) + * { + * var label = this.convertValueToString(cell); + * return 'Tooltip for '+label; + * } + * ]]></add> + * (end) + * + * "this" refers to the graph in the implementation, so for example to check if + * a cell is an edge, you use this.getModel().isEdge(cell) + * + * For replacing the default implementation of <getTooltipForCell> (rather than + * replacing the function on a specific instance), the following code should be + * used after loading the JavaScript files, but before creating a new mxGraph + * instance using <mxGraph>: + * + * (code) + * mxGraph.prototype.getTooltipForCell = function(cell) + * { + * var label = this.convertValueToString(cell); + * return 'Tooltip for '+label; + * } + * (end) + * + * Shapes & Styles: + * + * The implementation of new shapes is demonstrated in the examples. We'll assume + * that we have implemented a custom shape with the name BoxShape which we want + * to use for drawing vertices. To use this shape, it must first be registered in + * the cell renderer as follows: + * + * (code) + * graph.cellRenderer.registerShape('box', BoxShape); + * (end) + * + * The code registers the BoxShape constructor under the name box in the cell + * renderer of the graph. The shape can now be referenced using the shape-key in + * a style definition. (The cell renderer contains a set of additional shapes, + * namely one for each constant with a SHAPE-prefix in <mxConstants>.) + * + * Styles are a collection of key, value pairs and a stylesheet is a collection + * of named styles. The names are referenced by the cellstyle, which is stored + * in <mxCell.style> with the following format: [stylename;|key=value;]. The + * string is resolved to a collection of key, value pairs, where the keys are + * overridden with the values in the string. + * + * When introducing a new shape, the name under which the shape is registered + * must be used in the stylesheet. There are three ways of doing this: + * + * - By changing the default style, so that all vertices will use the new + * shape + * - By defining a new style, so that only vertices with the respective + * cellstyle will use the new shape + * - By using shape=box in the cellstyle's optional list of key, value pairs + * to be overridden + * + * In the first case, the code to fetch and modify the default style for + * vertices is as follows: + * + * (code) + * var style = graph.getStylesheet().getDefaultVertexStyle(); + * style[mxConstants.STYLE_SHAPE] = 'box'; + * (end) + * + * The code takes the default vertex style, which is used for all vertices that + * do not have a specific cellstyle, and modifies the value for the shape-key + * in-place to use the new BoxShape for drawing vertices. This is done by + * assigning the box value in the second line, which refers to the name of the + * BoxShape in the cell renderer. + * + * In the second case, a collection of key, value pairs is created and then + * added to the stylesheet under a new name. In order to distinguish the + * shapename and the stylename we'll use boxstyle for the stylename: + * + * (code) + * var style = new Object(); + * style[mxConstants.STYLE_SHAPE] = 'box'; + * style[mxConstants.STYLE_STROKECOLOR] = '#000000'; + * style[mxConstants.STYLE_FONTCOLOR] = '#000000'; + * graph.getStylesheet().putCellStyle('boxstyle', style); + * (end) + * + * The code adds a new style with the name boxstyle to the stylesheet. To use + * this style with a cell, it must be referenced from the cellstyle as follows: + * + * (code) + * var vertex = graph.insertVertex(parent, null, 'Hello, World!', 20, 20, 80, 20, + * 'boxstyle'); + * (end) + * + * To summarize, each new shape must be registered in the <mxCellRenderer> with + * a unique name. That name is then used as the value of the shape-key in a + * default or custom style. If there are multiple custom shapes, then there + * should be a separate style for each shape. + * + * Inheriting Styles: + * + * For fill-, stroke-, gradient- and indicatorColors special keywords can be + * used. The inherit keyword for one of these colors will inherit the color + * for the same key from the parent cell. The swimlane keyword does the same, + * but inherits from the nearest swimlane in the ancestor hierarchy. Finally, + * the indicated keyword will use the color of the indicator as the color for + * the given key. + * + * Scrollbars: + * + * The <containers> overflow CSS property defines if scrollbars are used to + * display the graph. For values of 'auto' or 'scroll', the scrollbars will + * be shown. Note that the <resizeContainer> flag is normally not used + * together with scrollbars, as it will resize the container to match the + * size of the graph after each change. + * + * Multiplicities and Validation: + * + * To control the possible connections in mxGraph, <getEdgeValidationError> is + * used. The default implementation of the function uses <multiplicities>, + * which is an array of <mxMultiplicity>. Using this class allows to establish + * simple multiplicities, which are enforced by the graph. + * + * The <mxMultiplicity> uses <mxCell.is> to determine for which terminals it + * applies. The default implementation of <mxCell.is> works with DOM nodes (XML + * nodes) and checks if the given type parameter matches the nodeName of the + * node (case insensitive). Optionally, an attributename and value can be + * specified which are also checked. + * + * <getEdgeValidationError> is called whenever the connectivity of an edge + * changes. It returns an empty string or an error message if the edge is + * invalid or null if the edge is valid. If the returned string is not empty + * then it is displayed as an error message. + * + * <mxMultiplicity> allows to specify the multiplicity between a terminal and + * its possible neighbors. For example, if any rectangle may only be connected + * to, say, a maximum of two circles you can add the following rule to + * <multiplicities>: + * + * (code) + * graph.multiplicities.push(new mxMultiplicity( + * true, 'rectangle', null, null, 0, 2, ['circle'], + * 'Only 2 targets allowed', + * 'Only shape targets allowed')); + * (end) + * + * This will display the first error message whenever a rectangle is connected + * to more than two circles and the second error message if a rectangle is + * connected to anything but a circle. + * + * For certain multiplicities, such as a minimum of 1 connection, which cannot + * be enforced at cell creation time (unless the cell is created together with + * the connection), mxGraph offers <validate> which checks all multiplicities + * for all cells and displays the respective error messages in an overlay icon + * on the cells. + * + * If a cell is collapsed and contains validation errors, a respective warning + * icon is attached to the collapsed cell. + * + * Auto-Layout: + * + * For automatic layout, the <getLayout> hook is provided in <mxLayoutManager>. + * It can be overridden to return a layout algorithm for the children of a + * given cell. + * + * Unconnected edges: + * + * The default values for all switches are designed to meet the requirements of + * general diagram drawing applications. A very typical set of settings to + * avoid edges that are not connected is the following: + * + * (code) + * graph.setAllowDanglingEdges(false); + * graph.setDisconnectOnMove(false); + * (end) + * + * Setting the <cloneInvalidEdges> switch to true is optional. This switch + * controls if edges are inserted after a copy, paste or clone-drag if they are + * invalid.

Model is an optional + * mxGraphModel. If no model is provided, a new mxGraphModel instance is + * used as the model. The container must have a valid owner document prior + * to calling this function in Internet Explorer. RenderHint is a string to + * affect the display performance and rendering in IE, but not in SVG-based + * browsers. The parameter is mapped to <dialect>, which may + * be one of <mxConstants.DIALECT_SVG> for SVG-based browsers, + * <mxConstants.DIALECT_STRICTHTML> for fastest display mode, + * <mxConstants.DIALECT_PREFERHTML> for faster display mode, + * <mxConstants.DIALECT_MIXEDHTML> for fast and <mxConstants.DIALECT_VML> + * for exact display mode (slowest). The dialects are defined in mxConstants. + * The default values are DIALECT_SVG for SVG-based browsers and + * DIALECT_MIXED for IE. + * + * The possible values for the renderingHint parameter are explained below: + * + * fast - The parameter is based on the fact that the display performance is + * highly improved in IE if the VML is not contained within a VML group + * element. The lack of a group element only slightly affects the display while + * panning, but improves the performance by almost a factor of 2, while keeping + * the display sufficiently accurate. This also allows to render certain shapes as HTML + * if the display accuracy is not affected, which is implemented by + * <mxShape.isMixedModeHtml>. This is the default setting and is mapped to + * DIALECT_MIXEDHTML. + * faster - Same as fast, but more expensive shapes are avoided. This is + * controlled by <mxShape.preferModeHtml>. The default implementation will + * avoid gradients and rounded rectangles, but more significant shapes, such + * as rhombus, ellipse, actor and cylinder will be rendered accurately. This + * setting is mapped to DIALECT_PREFERHTML. + * fastest - Almost anything will be rendered in Html. This allows for + * rectangles, labels and images. This setting is mapped to + * DIALECT_STRICTHTML. + * exact - If accurate panning is required and if the diagram is small (up + * to 100 cells), then this value should be used. In this mode, a group is + * created that contains the VML. This allows for accurate panning and is + * mapped to DIALECT_VML. + * + * Example: + * + * To create a graph inside a DOM node with an id of graph: + * (code) + * var container = document.getElementById('graph'); + * var graph = new mxGraph(container); + * (end) + * + * Parameters: + * + * container - Optional DOM node that acts as a container for the graph. + * If this is null then the container can be initialized later using + * <init>. + * model - Optional <mxGraphModel> that constitutes the graph data. + * renderHint - Optional string that specifies the display accuracy and + * performance.
