    • canStartZoomArea

      public boolean canStartZoomArea(MouseEvent mouseEvent)
      Description copied from interface: Zoomable
      Can a zoom area be started ?

      This is called from the zoomer when a zoom area is about to start to check that there are not reasons for not starting the area. For instance if some other mouse event is to take priority over the zoom, e.g. clicking on a detection which might initiate some other menu action.

      mouseEvent -
      Returns:
      true if zooming can start
