com.bbn.openmap.event.MapMouseMode
Interface for handling mouse behavior while the mouse is operating over the MapBean. A "MouseMode" object exists to interpret the meaning of mouse events. For instance, you could have a mode where mouse events (click, drag-select) are interpreted as navigation commands, (recenter, zoom-and-recenter). There may be other modes depending on how your application wants to interpret MouseEvents. @see AbstractMouseMode @see NavMouseMode @see SelectMouseMode @see NullMouseMode
