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 one above the label).
• 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.
