This sample demonstrates the LinkShiftingTool, which is an extra tool
|
|
that can be installed in the ToolManager to allow users to shift the end
|
|
point of the link to be anywhere along the sides of the port with which it
|
|
remains connected.
|
|
</p>
|
|
<p>
|
|
This only looks good for ports that occupy the whole of a rectangular node.
|
|
If you want to restrict the user's permitted sides, you can adapt the
|
|
<code>LinkShiftingTool.doReshape</code> method to do what you want.
