This handler is built-into - * <mxGraph.connectionHandler> and enabled using <mxGraph.setConnectable>. - * - * Example: - * - * (code) - * new mxConnectionHandler(graph, function(source, target, style) - * { - * edge = new mxCell('', new mxGeometry()); - * edge.setEdge(true); - * edge.setStyle(style); - * edge.geometry.relative = true; - * return edge; - * }); - * (end) - * - * Here is an alternative solution that just sets a specific user object for - * new edges by overriding <insertEdge>. - * - * (code) - * mxConnectionHandlerInsertEdge = mxConnectionHandler.prototype.insertEdge; - * mxConnectionHandler.prototype.insertEdge = function(parent, id, value, source, target, style) - * { - * value = 'Test'; - * - * return mxConnectionHandlerInsertEdge.apply(this, arguments); - * }; - * (end) - * - * Using images to trigger connections: - * - * This handler uses mxTerminalMarker to find the source and target cell for - * the new connection and creates a new edge using <connect>. The new edge is - * created using <createEdge> which in turn uses <factoryMethod> or creates a - * new default edge. - * - * The handler uses a "highlight-paradigm" for indicating if a cell is being - * used as a source or target terminal, as seen in MS Visio and other products. - * In order to allow both, moving and connecting cells at the same time, - * <mxConstants.DEFAULT_HOTSPOT> is used in the handler to determine the hotspot - * of a cell, that is, the region of the cell which is used to trigger a new - * connection. 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. To get more details about the - * actual connection point, <mxGraph.getConnectionConstraint> can be used. To resolve - * the port IDs, use <mxGraphModel.getCell>. - * - * (code) - * graph.connectionHandler.addListener(mxEvent.CONNECT, function(sender, evt) - * { - * var edge = evt.getProperty('cell'); - * var source = graph.getModel().getTerminal(edge, true); - * var target = graph.getModel().getTerminal(edge, false); - * - * var style = graph.getCellStyle(edge); - * var sourcePortId = style[mxConstants.STYLE_SOURCE_PORT]; - * var targetPortId = style[mxConstants.STYLE_TARGET_PORT]; - * - * mxLog.show(); - * mxLog.debug('connect', edge, source.id, target.id, sourcePortId, targetPortId); - * }); - * (end) - * - * Event: mxEvent.RESET - * - * Fires when the <reset> method is invoked. - * - * Constructor: mxConnectionHandler - * - * Constructs an event handler that connects vertices using the specified - * factory method to create the new edges.

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>.

All filenames are relative - to <mxClient.basePath>. - -Built-in Images: - - All images are loaded from the <mxClient.imageBasePath>, - which you can change to reflect your environment. The image variables can - also be changed individually. - - - mxGraph.prototype.collapsedImage - - mxGraph.prototype.expandedImage - - mxGraph.prototype.warningImage - - mxWindow.prototype.closeImage - - mxWindow.prototype.minimizeImage - - mxWindow.prototype.normalizeImage - - mxWindow.prototype.maximizeImage - - mxWindow.prototype.resizeImage - - mxPopupMenu.prototype.submenuImage - - mxUtils.errorImage - - mxConstraintHandler.prototype.pointImage - - The basename of the warning image (images/warning without extension) used in - <mxGraph.setCellWarning> is defined in <mxGraph.warningImage>. - -Resources: - - The <mxEditor> and <mxGraph> classes add the following resources to - <mxResources> at class loading time: - - - resources/editor*.properties - - resources/graph*.properties - - By default, the library ships with English and German resource files. - -Images: - - Recommendations for using images. 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.

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. Variables in the optional idrefs array are - * turned into references in the XML. The optional mapping - * may be used to map from variable names to XML attributes. - * The argument is created as follows: - * - * (code) - * var mapping = new Object(); - * mapping['variableName'] = 'attribute-name'; - * (end) - * - * Parameters: - * - * template - Prototypical instance of the object to be - * encoded/decoded. - * exclude - Optional array of fieldnames to be ignored. - * idrefs - Optional array of fieldnames to be converted to/from - * references. - * mapping - Optional mapping from field- to attributenames. - */ -function mxObjectCodec(template, exclude, idrefs, mapping) -{ - this.template = template; - - this.exclude = (exclude != null) ? exclude : []; - this.idrefs = (idrefs != null) ? idrefs : []; - this.mapping = (mapping != null) ? mapping : []; - - this.reverse = new Object(); - - for (var i in this.mapping) - { - this.reverse[this.mapping[i]] = i; - } -}; - -/** - * Variable: template - * - * Holds the template object associated with this codec. - */ -mxObjectCodec.prototype.template = null; - -/** - * Variable: exclude - * - * Array containing the variable names that should be - * ignored by the codec. - */ -mxObjectCodec.prototype.exclude = null; - -/** - * Variable: idrefs - * - * Array containing the variable names that should be - * turned into or converted from references.

The graph model acts as - * a wrapper around the cells which are in charge of storing the actual graph - * datastructure. The model acts as a transactional wrapper with event - * notification for all changes, whereas the cells contain the atomic - * operations for updating the actual datastructure. - * - * Layers: - * - * The cell hierarchy in the model must have a top-level root cell which - * contains the layers (typically one default layer), which in turn contain the - * top-level cells of the layers. This means each cell is contained in a layer. - * If no layers are required, then all new cells should be added to the default - * layer. - * - * Layers are useful for hiding and showing groups of cells, or for placing - * groups of cells on top of other cells in the display. To identify a layer, - * the <isLayer> function is used. It returns true if the parent of the given - * cell is the root of the model. - * - * Encoding the model: - * - * To encode a graph model, use the following code: - * - * (code) - * var enc = new mxCodec(); - * var node = enc.encode(graph.getModel()); - * (end) - * - * This will create an XML node that contains all the model information. - * - * Encoding and decoding changes: - * - * For the encoding of changes, a graph model listener is required that encodes - * each change from the given array of changes. - * - * (code) - * model.addListener(mxEvent.CHANGE, function(sender, evt) - * { - * var changes = evt.getProperty('edit').changes; - * var nodes = []; - * var codec = new mxCodec(); - * - * for (var i = 0; i < changes.length; i++) - * { - * nodes.push(codec.encode(changes[i])); - * } - * // do something with the nodes - * }); - * (end) - * - * For the decoding and execution of changes, the codec needs a lookup function - * that allows it to resolve cell IDs as follows: - * - * (code) - * var codec = new mxCodec(); - * codec.lookup = function(id) - * { - * return model.getCell(id); - * } - * (end) - * - * For each encoded change (represented by a node), the following code can be - * used to carry out the decoding and create a change object. - * - * (code) - * var changes = []; - * var change = codec.decode(node); - * change.model = model; - * change.execute(); - * changes.push(change); - * (end) - * - * The changes can then be dispatched using the model as follows. - * - * (code) - * var edit = new mxUndoableEdit(model, false); - * edit.changes = changes; - * - * edit.notify = function() - * { - * edit.source.fireEvent(new mxEventObject(mxEvent.CHANGE, - * 'edit', edit, 'changes', edit.changes)); - * edit.source.fireEvent(new mxEventObject(mxEvent.NOTIFY, - * 'edit', edit, 'changes', edit.changes)); - * } - * - * model.fireEvent(new mxEventObject(mxEvent.UNDO, 'edit', edit)); - * model.fireEvent(new mxEventObject(mxEvent.CHANGE, - * 'edit', edit, 'changes', changes)); - * (end) - * - * Event: mxEvent.CHANGE - * - * Fires when an undoable edit is dispatched. The <code>edit</code> property - * contains the <mxUndoableEdit>. The <code>changes</code> property contains - * the array of atomic changes inside the undoable edit. The changes property - * is <strong>deprecated</strong>, please use edit.changes instead. - * - * Example: - * - * For finding newly inserted cells, the following code can be used: - * - * (code) - * graph.model.addListener(mxEvent.CHANGE, function(sender, evt) - * { - * var changes = evt.getProperty('edit').changes; - * - * for (var i = 0; i < changes.length; i++) - * { - * var change = changes[i]; - * - * if (change instanceof mxChildChange && - * change.change.previous == null) - * { - * graph.startEditingAtCell(change.child); - * break; - * } - * } - * }); - * (end) - * - * - * Event: mxEvent.NOTIFY - * - * Same as <mxEvent.CHANGE>, this event can be used for classes that need to - * implement a sync mechanism between this model and, say, a remote model. In - * such a setup, only local changes should trigger a notify event and all - * changes should trigger a change event. - * - * Event: mxEvent.EXECUTE - * - * Fires between begin- and endUpdate and after an atomic change was executed - * in the model. The <code>change</code> property contains the atomic change - * that was executed. - * - * Event: mxEvent.BEGIN_UPDATE - * - * Fires after the <updateLevel> was incremented in <beginUpdate>. This event - * contains no properties. - * - * Event: mxEvent.END_UPDATE - * - * Fires after the <updateLevel> was decreased in <endUpdate> but before any - * notification or change dispatching. The <code>edit</code> property contains - * the <currentEdit>. - * - * Event: mxEvent.BEFORE_UNDO - * - * Fires before the change is dispatched after the update level has reached 0 - * in <endUpdate>. The <code>edit</code> property contains the <curreneEdit>. - * - * Event: mxEvent.UNDO - * - * Fires after the change was dispatched in <endUpdate>. The <code>edit</code> - * property contains the <currentEdit>. - * - * Constructor: mxGraphModel - * - * Constructs a new graph model.

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.
