|
|
* The DragCreatingTool lets the user create a new node by dragging in the background
|
|
* to indicate its size and position.
|
|
* <p/>
|
|
* The default drag selection box is a magenta rectangle.
|
|
* You can modify the {@link #box} to customize its appearance.
|
|
* <p/>
|
|
* This tool will not be able to start running unless you have set the
|
|
* {@link #archetypeNodeData} property to an object that can be copied and added to the diagram's model.
|
|
* <p/>
|
|
* You can use this tool in a modal manner by executing:
|
|
* <pre><code>
|
|
* diagram.currentTool = new DragCreatingTool();
|
|
* </code></pre>
|
|
* <p/>
|
|
* Use this tool in a mode-less manner by executing:
|
|
* <pre><code>
|
|
* myDiagram.toolManager.mouseMoveTools.insertAt(2, new DragCreatingTool());
|
|
* </code></pre>
|
|
* However when used mode-lessly as a mouse-move tool, in {@link ToolManager#mouseMoveTools},
|
|
* this cannot start running unless there has been a motionless delay
|
|
* after the mouse-down event of at least {@link #delay} milliseconds.
|
|
* <p/>
|
|
* This tool does not utilize any {@link Adornment}s or tool handles,
|
|
* but it does temporarily add the {@link #box} Part to the diagram.
|
|
* This tool does conduct a transaction when inserting the new node.
