Class JungPickingGraphMousePlugin<V,E>

java.lang.Object
edu.uci.ics.jung.visualization.control.AbstractGraphMousePlugin
ghidra.graph.viewer.event.mouse.JungPickingGraphMousePlugin<V,E>
Type Parameters:
V - the vertex type
E - the edge type
All Implemented Interfaces:
edu.uci.ics.jung.visualization.control.GraphMousePlugin, MouseListener, MouseMotionListener, EventListener
Direct Known Subclasses:
VisualGraphPickingGraphMousePlugin
public class JungPickingGraphMousePlugin<V,E> extends edu.uci.ics.jung.visualization.control.AbstractGraphMousePlugin implements MouseListener, 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.

  • Constructor Details

    • JungPickingGraphMousePlugin

      public JungPickingGraphMousePlugin()
      create an instance with default settings

    • JungPickingGraphMousePlugin

      public JungPickingGraphMousePlugin(int selectionModifiers, int addToSelectionModifiers)
      create an instance with overrides
      Parameters:
      selectionModifiers - for primary selection
      addToSelectionModifiers - for additional selection

  • Method Details

    • getLensColor

      public Color getLensColor()
      Returns:
      Returns the lensColor.

    • setLensColor

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

    • mousePressed

      public void mousePressed(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 MouseListener
      Parameters:
      e - the event

    • mouseReleased

      public void mouseReleased(MouseEvent e)
      If the mouse is dragging a rectangle, pick the Vertices contained in that rectangle clean up settings from mousePressed
      Specified by:
      mouseReleased in interface MouseListener

    • mouseDragged

      public void mouseDragged(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
      Specified by:
      mouseDragged in interface MouseMotionListener

      protected void pickContainedVertices(edu.uci.ics.jung.visualization.VisualizationViewer<V,E> vv, Point2D down, Point2D out, boolean clear)
      pick the vertices inside the rectangle created from points 'down' and 'out' (two diagonally opposed corners of the rectangle)
      Parameters:
      vv - the viewer containing the layout and picked state
      down - one corner of the rectangle
      out - the other corner of the rectangle
      clear - whether to reset existing picked state
