InputMap / ActionMap actions leave characters in TextArea

[Chris Kimball]

I've added a JPopupMenu to a JPanel with a TextArea in it. The popup menu is attached to the TextArea with the usual MouseListener.

To bring up the popup menu with a keystroke, I've gotten the InputMap and added a (key, action) pair to it. The key is an alt P, the action is a defined Action instance.

The software works fine in popping up the menu and closing the menu. Alas, if the focus is on the text area, alt p ALSO produces a "pi" symbol in the text area.

The Action class uses an ActionEvent that doesn't have a consume() method. What sort of action for the ActionMap should I be using so that I can consume the alt P?


Thanks,

Chris

Here's a snippet :

  JRootPane rp = H.SC.getRootPane() ;
  rp.setDefaultButton(done) ;  

  InputMap inputMap = rp.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW) ;
  KeyStroke[] keyStrokes = inputMap.allKeys();
  if(keyStrokes != null){
    inputMap.put(KeyStroke.getKeyStroke("alt P"), "popup") ;   	
  }
  else{
  	System.out.println("GUI: keyStrokes list is null.") ;
  }
  PAction popupaction = new PAction(H) ;
  ActionMap actionMap = rp.getActionMap() ;
  actionMap.put("popup", popupaction) ;

If you don't want the default action of the keystroke to affect the text area, remove that mapping from the appropriate input map of the text area.
