public class OutlineMouseListener

extends MouseAdapter

implements MouseListener

OutlineMouseListener listens for and reacts to mouse events on an Outline.

Note: if MouseEvent.isPopupTrigger() isn't working on your platform, set eventIsPopupTriggerIsImplemented to false; then it will popup on any button besides simple button-1 press, or any modified (shift, alt, etc.) button.

Field Summary

static int	dbgLev For debugging popup menu items: if dbgLev > 0, traces popup related events on System.err
boolean	eventIsPopupTriggerIsImplemented set this to false if MouseEvent.isPopupTrigger() isn't working

Constructor Summary

OutlineMouseListener(JTree jTree)

Method Summary

static void	dbgOut(String s)
boolean	isPopupTrigger(MouseEvent event) true if event.isPopupTrigger() is true, or if event.isPopupTrigger() has never been true, then true if mouse press is modified (button 2 or 3, or pressed with shift, control, meta, or alt).
void	mouseClicked(MouseEvent event)
void	mousePressed(MouseEvent event)
void	mouseReleased(MouseEvent event)
void	popup(MouseEvent event) If triggered over a OutlineNode display, creates empty PopupMenu, calls OutlineRenderer.addPopupMenuTitle(java.awt.PopupMenu, edu.mit.ai.psg.ui.outliner.OutlineNode, javax.swing.tree.TreePath, javax.swing.JTree) and OutlineRenderer.addPopupMenuItems(java.awt.PopupMenu, edu.mit.ai.psg.ui.outliner.OutlineNode, javax.swing.tree.TreePath, javax.swing.JTree) to give it a title and component-specific menu items (otherwise, title is just outlineNode.toString()).

public OutlineMouseListener(JTree jTree)

Method Detail

mouseClicked

public void mouseClicked(MouseEvent event)

Specified by:

mouseClicked in interface MouseListener

Overrides:

mouseClicked in class MouseAdapter

mouseReleased

public void mouseReleased(MouseEvent event)

Specified by:

mouseReleased in interface MouseListener

Overrides:

mouseReleased in class MouseAdapter

mousePressed

public void mousePressed(MouseEvent event)

Specified by:

mousePressed in interface MouseListener

Overrides:

mousePressed in class MouseAdapter

isPopupTrigger

public boolean isPopupTrigger(MouseEvent event)

true if event.isPopupTrigger() is true, or if event.isPopupTrigger() has never been true, then true if mouse press is modified (button 2 or 3, or pressed with shift, control, meta, or alt). (MouseEvent.isPopupTrigger isn't been implemented correctly on some platforms)

popup

public void popup(MouseEvent event)

If triggered over a OutlineNode display, creates empty PopupMenu, calls OutlineRenderer.addPopupMenuTitle(java.awt.PopupMenu, edu.mit.ai.psg.ui.outliner.OutlineNode, javax.swing.tree.TreePath, javax.swing.JTree) and OutlineRenderer.addPopupMenuItems(java.awt.PopupMenu, edu.mit.ai.psg.ui.outliner.OutlineNode, javax.swing.tree.TreePath, javax.swing.JTree) to give it a title and component-specific menu items (otherwise, title is just outlineNode.toString()). Then calls OutlineMaker.addPopupMenuItems(java.awt.PopupMenu, edu.mit.ai.psg.ui.outliner.OutlineNode, javax.swing.tree.TreePath, javax.swing.JTree) on renderer's OutlineMaker to add system-specific menu items. Finally, pops up the menu.
