getCursor

public java.awt.Cursor getCursor()
Returns a cursor for the handle.

Specified by:
getCursor in interface Handle
Overrides:
getCursor in class AbstractHandle
Returns:
Returns a move cursor, if the figure is transformable. Returns a default cursor otherwise.

trackStart

public void trackStart(java.awt.Point anchor,
                       int modifiersEx)
Description copied from interface: Handle
Tracks the start of the interaction. The default implementation does nothing.

Parameters:
anchor - the position where the interaction started

Description copied from interface: Handle
Tracks a step of the interaction.

Parameters:
anchor - the position where the interaction started
