JSlider key bindings

So I'm a bit nonplussed at the JSlider default key bindings for vertical sliders.

• Home: goes to the bottom (why not the top?)
• End开发者_如何学Python: goes to the top (why not the bottom?)
• PageUp/PageDown: direction good, but goes up by some amount K which I can't control
• up/down arrow keys: direction good, but goes up by 1, and I have a high-granularity slider (0 to 65535) which I would like to have a little more intuitive control over.

Is there a way to customize this behavior?

You can access the keybindings via the getInputMap and getActionMap methods. For example, to switch the home/end key bindings (make Home go to the top, and end go to the bottom):

InputMap im = yourSlider.getInputMap();
im.put(KeyStroke.getKeyStroke("HOME"), "maxScroll");
im.put(KeyStroke.getKeyStroke("END"), "minScroll");

Here's a tutorial on key bindings.

There isn't a straightforward way as for menus. But you can probably use actions for your purpose: http://java.sun.com/docs/books/tutorial/uiswing/misc/action.html
