Method Detail

dbgOut

public static void dbgOut(String s)

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 mouse press is modified (button 2 or 3, or pressed with shift, control, meta, or alt). (event.isPopupTrigger hasn't been reliable on some platforms)

popup

public void popup(MouseEvent event)

Creates empty PopupMenu. If myComponent is an OutlineTree, calls myComponent.addPopupMenuTitle(menu) and myComponent.addPopupMenuItems(menu) to give it a title and component-specific menu items (otherwise, title is just myComponent.toString()). Then calls Outliner.outliner.addPopupMenuItems(menu) to add system-specific menu items. Finally, pops up the menu.
