org.das2.event.MouseModule

A MouseModule is a pluggable unit that promotes simple mouse events into human events or actions that are useful for science analysis. Each component has a mouseInputAdapter that manages a set of mouseModules, one is active at any given time. The DasMouseInputAdapter will delegate mouse events, key events, and mouse wheel events to the active mouse module. This base class will be extended by instances of MouseModule, overriding methods they wish to handle.
