public class MoveSelectionMode

extends ViewMode

While the mouse is being dragged the selected parts will be moved around. If the mouse gets released the operation will end and all registered views will receive an update event.

Method Detail

mouseShiftPressedLeft

public void mouseShiftPressedLeft(double x,
                                  double y)

Initiates the movement of the selected graph elements.

Overrides:

mouseShiftPressedLeft in class ViewMode

Parameters:

x - the x-coordinate of the mouse event in world coordinates.

y - the y-coordinate of the mouse event in world coordinates.

mousePressedLeft

public void mousePressedLeft(double x,
                             double y)

Initiates the movement of the selected graph elements.

Overrides:

mousePressedLeft in class ViewMode

Parameters:

x - the x-coordinate of the mouse event in world coordinates.

y - the y-coordinate of the mouse event in world coordinates.

mouseShiftReleasedLeft

public void mouseShiftReleasedLeft(double x,
                                   double y)

Terminates the movements of the selected graph elements.

Overrides:

mouseShiftReleasedLeft in class ViewMode

Parameters:

x - the x-coordinate of the mouse event in world coordinates.

y - the y-coordinate of the mouse event in world coordinates.

mouseReleasedLeft

public void mouseReleasedLeft(double x,
                              double y)

Terminates the movements of the selected graph elements.

Overrides:

mouseReleasedLeft in class ViewMode

Parameters:

x - the x-coordinate of the mouse event in world coordinates.

y - the y-coordinate of the mouse event in world coordinates.

mouseDraggedLeft

public void mouseDraggedLeft(double x,
                             double y)

Moves the selected graph elements around.

Overrides:

mouseDraggedLeft in class ViewMode

Parameters:

x - the x-coordinate of the mouse event in world coordinates.

y - the y-coordinate of the mouse event in world coordinates.

selectionOnMove

protected void selectionOnMove(double dx,
                               double dy,
                               double x,
                               double y)

Performs an action when the selection is moving. By default this method does nothing. Subclasses may want to override this.

selectionMovedAction

protected void selectionMovedAction(double dx,
                                    double dy,
                                    double x,
                                    double y)

Performs an action after the selection was moved. By default this method does nothing. Subclasses may want to override this.

getNodesToBeMoved

protected NodeList getNodesToBeMoved()

Returns the nodes that should will be moved by this view mode. By default the selected nodes of the graph will be returned.

getBendsToBeMoved

protected BendList getBendsToBeMoved()

Returns the bends that should will be moved by this view mode. By default the selected bends of the graph will be returned.
