Label Handle Provider Demo
This demo shows how to implement custom IHandle s that allow interactive
resizing and rotation of labels.
Things to Try
Select a node label or an edge label and change its size by dragging its resize handle
The Free Node Label can also be rotated: Select that label and drag its rotate
handle (the dot).
Take a look at the source code, especially LabelHandleProvider,
LabelResizeHandle, and LabelRotateHandle.
Note that the actual resize behavior depends on the label model parameter, since some
parameters constrain the label's center to stay at the same position. For these
parameters, the label is resized symmetrically in both directions.
