<div id=Content><div class="CClass"><div class=CTopic id=MainTopic><h1 class=CTitle><a name="mxKeyHandler"></a>mxKeyHandler</h1><div class=CBody><p>Event handler that listens to keystroke events. This is not a singleton, however, it is normally only required once if the target is the document element (default).</p><p>This handler installs a key event listener in the topmost DOM node and processes all events that originate from descandants of <mxGraph.container> or from the topmost DOM node. The latter means that all unhandled keystrokes are handled by this object regardless of the focused state of the <a href="#mxKeyHandler.graph" class=LVariable id=link29 onMouseOver="ShowTip(event, 'tt2', 'link29')" onMouseOut="HideTip('tt2')">graph</a>.</p><h4 class=CHeading>Example</h4><p>The following example creates a key handler that listens to the delete key (46) and deletes the selection cells if the graph is enabled.</p><blockquote><pre class="prettyprint">var keyHandler = new mxKeyHandler(graph);
|
|
keyHandler.bindKey(46, function(evt)
|
|
{
|
|
if (graph.isEnabled())
|
|
{
|
|
graph.removeCells();
|
|
}
|
|
});</pre></blockquote><h4 class=CHeading>Keycodes</h4><p>See <a href="http://tinyurl.com/yp8jgl" class=LURL target=_top>http://tinyurl.com/yp8jgl</a> or <a href="http://tinyurl.com/229yqw" class=LURL target=_top>http://tinyurl.com/229yqw</a> for a list of keycodes or install a key event listener into the document element and print the key codes of the respective events to the console.</p><p>To support the Command key and the Control key on the Mac, the following code can be used.</p><blockquote><pre class="prettyprint">keyHandler.getFunction = function(evt)
|
|
{
|
|
if (evt != null)
|
|
{
|
|
return (mxEvent.isControlDown(evt) || (mxClient.IS_MAC && evt.metaKey)) ? this.controlKeys[evt.keyCode] : this.normalKeys[evt.keyCode];
