  • All Implemented Interfaces:
    MouseTransform
    Enclosing class:
    AbstractMouseTransformFactory
    protected class AbstractMouseTransformFactory.InvalidMouseTransform
extends java.lang.Object
implements MouseTransform
    This mouse transform does nothing, it simply returns an invalid cursor, and can be used by MouseTransform factories to notify the user of an invalid UI action.

      • start

        public void start​(PEMouseEvent e)
        Called when the mouse is pressed. The transform should do the initialization work here.
        Specified by:
        start in interface MouseTransform
        Since:
        jpicedt 1.3.2

      • process

        public void process​(PEMouseEvent e)
        Called when the mouse is dragged. Element geometry update should occur here.
        Specified by:
        process in interface MouseTransform
        Since:
        jpicedt 1.3.2

      • next

        public boolean next​(PEMouseEvent e)
        Called when the mouse is released
        Specified by:
        next in interface MouseTransform
        Returns:
        true if there's another task in the sequence, false if mouse-transform has completed with this mouse-event.
