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. This cookie - * only exists if <onInit> is implemented. - * - * Event: mxEvent.OPEN - * - * Fires after a file was opened in <open>. The <code>filename</code> property - * contains the filename that was used. The same value is also available in - * <filename>. - * - * Event: mxEvent.SAVE - * - * Fires after the current file was saved in <save>. The <code>url</code> - * property contains the URL that was used for saving. - * - * Event: mxEvent.POST - * - * Fires if a successful response was received in <postDiagram>. The - * <code>request</code> property contains the <mxXmlRequest>, the - * <code>url</code> and <code>data</code> properties contain the URL and the - * data that were used in the post request. - * - * Event: mxEvent.ROOT - * - * Fires when the current root has changed, or when the title of the current - * root has changed. This event has no properties. - * - * Event: mxEvent.SESSION - * - * Fires when anything in the session has changed. The <code>session</code> - * property contains the respective <mxSession>. - * - * Event: mxEvent.BEFORE_ADD_VERTEX - * - * Fires before a vertex is added in <addVertex>. The <code>vertex</code> - * property contains the new vertex and the <code>parent</code> property - * contains its parent. - * - * Event: mxEvent.ADD_VERTEX - * - * Fires between begin- and endUpdate in <addVertex>. The <code>vertex</code> - * property contains the vertex that is being inserted. - * - * Event: mxEvent.AFTER_ADD_VERTEX - * - * Fires after a vertex was inserted and selected in <addVertex>. The - * <code>vertex</code> property contains the new vertex. - * - * Example: - * - * For starting an in-place edit after a new vertex has been added to the - * graph, the following code can be used. - * - * (code) - * editor.addListener(mxEvent.AFTER_ADD_VERTEX, function(sender, evt) - * { - * var vertex = evt.getProperty('vertex'); - * - * if (editor.graph.isCellEditable(vertex)) - * { - * editor.graph.startEditingAtCell(vertex); - * } - * }); - * (end) - * - * Event: mxEvent.ESCAPE - * - * Fires when the escape key is pressed. The <code>event</code> property - * contains the key event. - * - * Constructor: mxEditor - * - * Constructs a new editor.
