JScrollBar, remove keyListener?

Hey you all, just a quick question of what i havent found anywhere. Im adding a scrollpane to a JPanel, with 2 JScrollBars. One vertical and one horizontal. Everything works fine just that i dont want the ScrollBars to scroll using the arrow keys. How do i achieve this?

I´ve been checking out adjustmentlisteners but really havent found anything of high value to me. Thanks for any help!

you have to tweak the keybinding in the scrollPane's inputMap and point the navigation keys into nirwana, like:

    InputMap inputMap = scrollPane.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);
    inputMap.put(KeyStroke.getKeyStroke("RIGHT"), "do-nothing");
    // same for all navigation keys you want to disable
    ...

to find which keyStrokes are registered, look into the BasicLookFeel - the section in getDefaults which relates to "ScrollPane"

Beware: that's highly unusual, you user's might be annoyed!
