Package ghidra.graph.viewer.event.mouse

Class JungPickingGraphMousePlugin<V,​E>

  • Type Parameters:
    V - the vertex type
    E - the edge type
    All Implemented Interfaces:
    edu.uci.ics.jung.visualization.control.GraphMousePlugin, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.util.EventListener
    Direct Known Subclasses:
    VisualGraphPickingGraphMousePlugin
    public class JungPickingGraphMousePlugin<V,​E>
extends edu.uci.ics.jung.visualization.control.AbstractGraphMousePlugin
implements java.awt.event.MouseListener, java.awt.event.MouseMotionListener
    PickingGraphMousePlugin supports the picking of graph elements with the mouse. MouseButtonOne picks a single vertex or edge, and MouseButtonTwo adds to the set of selected Vertices or EdgeType. If a Vertex is selected and the mouse is dragged while on the selected Vertex, then that Vertex will be repositioned to follow the mouse until the button is released.

    • Method Detail

      • getLensColor

        public java.awt.Color getLensColor()
        Returns:
        Returns the lensColor.

      • setLensColor

        public void setLensColor​(java.awt.Color lensColor)
        Parameters:
        lensColor - The lensColor to set.

      • mousePressed

        public void mousePressed​(java.awt.event.MouseEvent e)
        For primary modifiers (default, MouseButton1): pick a single Vertex or Edge that is under the mouse pointer. If no Vertex or edge is under the pointer, unselect all picked Vertices and edges, and set up to draw a rectangle for multiple selection of contained Vertices. For additional selection (default Shift+MouseButton1): Add to the selection, a single Vertex or Edge that is under the mouse pointer. If a previously picked Vertex or Edge is under the pointer, it is un-picked. If no vertex or Edge is under the pointer, set up to draw a multiple selection rectangle (as above) but do not unpick previously picked elements.
        Specified by:
        mousePressed in interface java.awt.event.MouseListener
        Parameters:
        e - the event

      • mouseReleased

      • mouseDragged

        public void mouseDragged​(java.awt.event.MouseEvent e)
        If the mouse is over a picked vertex, drag all picked vertices with the mouse. If the mouse is not over a Vertex, draw the rectangle to select multiple Vertices
