<p>The ClickSelectingTool selects and deselects <a href="Part.html">Part</a>s when there is a click.
|
|
It does this by calling <a href="Tool.html#standardMouseSelect">Tool.standardMouseSelect</a>.
|
|
It is also responsible for handling and dispatching click events on <a href="GraphObject.html">GraphObject</a>s
|
|
by calling <a href="Tool.html#standardMouseClick">Tool.standardMouseClick</a>.</p>
|
|
<p>Note that this tool avoids raising click events on objects that are in temporary layers.
|
|
This is to prevent parts such as selection adornments from interfering with clicking on selected nodes or links.
|
|
(Adornments are in the "Adornment" <a href="Layer.html">Layer</a>, which <a href="Layer.html#isTemporary">Layer.isTemporary</a>.)
|
|
However this means that if you add a <a href="GraphObject.html#click">GraphObject.click</a> event handler on a GraphObject in an Adornment,
|
|
it will not be called.
|
|
You can get it to be called by setting <a href="GraphObject.html#isActionable">GraphObject.isActionable</a> to true on that object in the adornment.</p>
|
|
<p>This tool is a standard mouse-up tool, the <a href="ToolManager.html#clickSelectingTool">ToolManager.clickSelectingTool</a>.</p>
|
|
<p>This tool does not utilize any <a href="Adornment.html">Adornment</a>s or tool handles.
|
|
This tool does not modify the model or conduct any transaction.</p>
|
|
<p>An example customization of this tool is shown in the <a href="../../extensions/TreeMap.html">Tree Map</a> sample,
|
|
where the <a href="Tool.html#standardMouseSelect">Tool.standardMouseSelect</a> method is overridden to permit the user to cycle through
|
|
the chain of containing groups, changing the selection on each click to the next containing group.</p>
|
|
<p>If you want to programmatically select a Part, you can set <a href="Part.html#isSelected">Part.isSelected</a> or call <a href="Diagram.html#select">Diagram.select</a>.
|
|
If you want to know which Part is at a particular point, you can call <a href="Diagram.html#findPartAt">Diagram.findPartAt</a>.</p>
