All keys to a list, for example VK_A..Z for user to select

Question

Hello All,

I am making a program that allows user to custom keyboard shortcuts, for this i need the available keys to be displayed, what is the best way to achieve this in java swing?

    KeyEvent.class.getDeclaredFields()

I am intrested in dynamic example of below,

keysLST.setModel(new javax.swing.DefaultComboBoxModel(new String[] { "CTRL", "ALT", "SHIFT" }));

one way i know is to get all from the keyevent class but i am not sure how to integrate it to the list. any help would be appreciated.

Thanks

Instead of picking from a list, add a KeyListener to any component (a JTextField works) and record the key code as the user presses the key. You can also record modifiers (ctrl,alt,shift) this way.

public void keyPressed(KeyEvent e)
{
    int keyTheUserJustPressed = e.getKeyCode();

    // then use for ctrl/alt/shift
    e.getModifiersEx();

    // or use
    e.isAltDown();
    e.isShiftDown();
}
