JInternalFrame and Keybinding

How do I bind a function key say(F11 etc) to a JInternalFrame, so it can activate a particular action.

I tried with the following

  this.getInputMap().put(KeyStroke.getKeyStroke("F11"), new AbstractAction() {
        public void actionPerformed(ActionEvent e) {
               System.out.println("Called");
            }
        });

but it never gets called? Or please suggest how to activate a button inside a JInternalFrame using function key.

Thanks Azlam

Solution

  • Well, focus is never on the internal frame itself, focus is on a component on the internal frame.

    So you should probably be adding the binding by using

    internalFrame.getRootPane()....

    You may also need to use 

    "WHEN_ANCESTOR_OF_FOCUSED_COMPONENT"

    input map.

    The blog entry on Key Bindings explains this in more detail.
