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.

MouseModule( org.das2.graph.DasCanvasComponent parent )

create the mouse module for the parent component. This is without a drag renderer, and the class name is used for the label. paint graphic feedback to the human operator.

MouseModule( org.das2.graph.DasCanvasComponent parent, org.das2.event.DragRenderer dragRenderer, String label )

create the mouse module for the parent component using the dragRenderer to paint graphic feedback to the human operator. For example, the dragRenderer might draw a box during the click-drag-release mouse action, and then on release this mouse module creates the event used elsewhere.
