CrossControl(int type, VolumeDataModel m)
The type is one of VolumeView.SAGITTAL, CORONAL or TRANSVERSE

Method Summary

boolean	doCommand(DoCommand cmd) Process a command if this command makes sense for this object (the target is is expected).
int	getMouseEvents() Currently this just requires MOUSE_RELEASE
IconOverlay	getOverlay() Return the CrossOverlay
protected boolean	handle(double[] newLoc) Handle the new location and return true if anything changed.
DoCommand	process(PercentMouseEvent evt) Process the event and return a DoEvent that will be dispatched.
