<div id=Content><div class="CClass"><div class=CTopic id=MainTopic><h1 class=CTitle><a name="mxUndoManager"></a>mxUndoManager</h1><div class=CBody><p>Implements a command history. When changing the graph model, an <mxUndoableChange> object is created at the start of the transaction (when model.beginUpdate is called). All atomic changes are then added to this object until the last model.endUpdate call, at which point the <a href="mxUndoableEdit-js.html#mxUndoableEdit" class=LClass id=link18 onMouseOver="ShowTip(event, 'tt13', 'link18')" onMouseOut="HideTip('tt13')">mxUndoableEdit</a> is dispatched in an event, and added to the history inside <a href="#mxUndoManager.mxUndoManager" class=LFunction id=link19 onMouseOver="ShowTip(event, 'tt4', 'link19')" onMouseOut="HideTip('tt4')">mxUndoManager</a>. This is done by an event listener in <a href="../editor/mxEditor-js.html#mxEditor.installUndoHandler" class=LFunction id=link20 onMouseOver="ShowTip(event, 'tt14', 'link20')" onMouseOut="HideTip('tt14')">mxEditor.installUndoHandler</a>.</p><p>Each atomic change of the model is represented by an object (eg. <a href="../model/mxGraphModel-js.html#mxRootChange" class=LClass id=link21 onMouseOver="ShowTip(event, 'tt15', 'link21')" onMouseOut="HideTip('tt15')">mxRootChange</a>, <a href="../model/mxGraphModel-js.html#mxChildChange" class=LClass id=link22 onMouseOver="ShowTip(event, 'tt16', 'link22')" onMouseOut="HideTip('tt16')">mxChildChange</a>, <a href="../model/mxGraphModel-js.html#mxTerminalChange" class=LClass id=link23 onMouseOver="ShowTip(event, 'tt17', 'link23')" onMouseOut="HideTip('tt17')">mxTerminalChange</a> etc) which contains the complete undo information. The <a href="#mxUndoManager.mxUndoManager" class=LFunction id=link24 onMouseOver="ShowTip(event, 'tt4', 'link24')" onMouseOut="HideTip('tt4')">mxUndoManager</a> also listens to the <a href="../view/mxGraphView-js.html#mxGraphView" class=LClass id=link25 onMouseOver="ShowTip(event, 'tt18', 'link25')" onMouseOut="HideTip('tt18')">mxGraphView</a> and stores it’s changes to the current root as insignificant undoable changes, so that drilling (step into, step up) is undone.</p><p>This means when you execute an atomic change on the model, then change the current root on the view and click undo, the change of the root will be undone together with the change of the model so that the display represents the state at which the model was changed. However, these changes are not transmitted for sharing as they do not represent a state change.</p><h4 class=CHeading>Example</h4><p>When adding an undo manager to a graph, make sure to add it to the model and the view as well to maintain a consistent display across multiple undo/redo steps.</p><blockquote><pre class="prettyprint">var undoManager = new mxUndoManager();
|
|
var listener = function(sender, evt)
|
|
{
|
|
undoManager.undoableEditHappened(evt.getProperty('edit'));
|
|
};
|
|
graph.getModel().addListener(mxEvent.UNDO, listener);
|
|
graph.getView().addListener(mxEvent.UNDO, listener);</pre></blockquote><p>The code creates a function that informs the undoManager of an undoable edit and binds it to the undo event of <a
