Constructor Summary

TMNavigateUI.AssociationSwapListener(TNode fromNode, TNode toNode, MouseEvent e)

Method Summary

void	disableListener() Disables the listener and returns the graph to normal functioning.
void	initializeDrag(MouseEvent e) Upon initialization, temporarily fixes the moused over TNode, then creates a phantom (marked provisional) TNode linked by an arrow-style GraphEdge.
void	mouseDragged(MouseEvent e) Drags the phantom TNode.
void	mouseExited(MouseEvent e)
void	mouseReleased(MouseEvent e)
void	releaseDrag(MouseEvent e) Reverts the graph back to its pre-phantom state.

Constructor Detail

TMNavigateUI.AssociationSwapListener

public TMNavigateUI.AssociationSwapListener(TNode fromNode,
                                            TNode toNode,
                                            MouseEvent e)

Method Detail

initializeDrag

public void initializeDrag(MouseEvent e)

Upon initialization, temporarily fixes the moused over TNode, then creates a phantom (marked provisional) TNode linked by an arrow-style GraphEdge. This continues via mouseDragged() until a mouse release.

releaseDrag

public void releaseDrag(MouseEvent e)

Reverts the graph back to its pre-phantom state. If a MouseEvent is provided a new Topic is created at point p. If the Control key is down, a new Association will be created between the initial drag Topic and the new Topic. Furthermore, if the Shift key is down, the previous Association template (if available) will be used as the template for the new Association.

mouseDragged

public void mouseDragged(MouseEvent e)

Drags the phantom TNode.

Specified by:

mouseDragged in interface MouseMotionListener

Overrides:

mouseDragged in class MouseInputAdapter

mouseReleased

public void mouseReleased(MouseEvent e)

Specified by:

mouseReleased in interface MouseListener

Overrides:

mouseReleased in class MouseInputAdapter

mouseExited

public void mouseExited(MouseEvent e)

Specified by:

mouseExited in interface MouseListener

Overrides:

mouseExited in class MouseInputAdapter

disableListener

public void disableListener()

Disables the listener and returns the graph to normal functioning.
