JInternalFrame and Keybinding

Question

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

Answer 1

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.

Answer 2

JInternalFrame has troubles with KeyListeners and KeyBindings. To solve this problem try using JDialog instead of JInternalFrame.
