      • checkModifiers

        public boolean checkModifiers​(java.awt.event.MouseEvent e)
        Overridden to be more flexible, and pass events with key combinations. The default responds to both ButtonOne and ButtonOne+Shift
        Specified by:
        checkModifiers in interface GraphMousePlugin
        Overrides:
        checkModifiers in class AbstractGraphMousePlugin
        Parameters:
        e - an event to compare to
        Returns:
        whether the member modifers match the event modifiers

      • mousePressed

        public void mousePressed​(java.awt.event.MouseEvent e)
        If the mouse is pressed in an empty area, create a new vertex there. If the mouse is pressed on an existing vertex, prepare to create an edge from that vertex to another
        Specified by:
        mousePressed in interface java.awt.event.MouseListener

      • mouseReleased

        public void mouseReleased​(java.awt.event.MouseEvent e)
        If startVertex is non-null, and the mouse is released over an existing vertex, create an undirected edge from startVertex to the vertex under the mouse pointer. If shift was also pressed, create a directed edge instead.
        Specified by:
        mouseReleased in interface java.awt.event.MouseListener

      • mouseDragged

        public void mouseDragged​(java.awt.event.MouseEvent e)
