Package be.ugent.caagt.swirl.mouse Description

Provides mouse overlay panels which enable different mouse 'tools' to be associated with a single panel. Useful when mouse actions differ according to context: clicking on a graphical object and dragging it activates one tool, while clicking (and dragging) on the panel but not on an object activates another tool (which for instance displays a selection rectangle). This allows a complicated mouse listener to be split into several independent classes.

A group of related mouse actions should be implemented as a subclass of MouseHandler. A set of mouse handlers can be registered with a single MouseTool which must then be associated to a MouseOverlay. Finally, this panel should be added as a child to a given component and will then track all mouse actions for that component.
