KeyEvents for jnativehook

Question

I'm trying to use jnativehook for global keyboard listeners but it seems like the key codes are different. For example, I want to check if ALT + I is pressed:

addNativeKeyListener(new NativeKeyAdapter()
{
    @Override
    public void nativeKeyReleased(NativeKeyEvent keyEvent)
    {
        val modifiers = keyEvent.getModifiers();
        val altPressed = modifiers == ALT_L_MASK;
        LOGGER.log(INFO, "Modifiers: " + modifiers + " ALT: " + ALT_L_MASK);

        if (!altPressed)
        {
            return;
        }

        val keyCode = keyEvent.getKeyCode();
        LOGGER.log(INFO, "Key code: " + keyCode + " VK_I: " + VK_I);
        if (keyCode != VK_I)
        {
            return;
        }

        LOGGER.log(INFO, "Button combination recognized...");
    }
});

Checking for the ALT modifier to be pressed works as expected but checking for the I button does not work as expected:

INFO: Modifiers: 8 ALT: 8
Oct 06, 2018 2:38:44 PM com.myCompany.Main nativeKeyReleased
INFO: Key code: 23 VK_I: 73

Why is the key code 23 when I release the I button? How do I check for the I button without hard-coding those seemingly random integer constants? Java offers the KeyEvent class for key codes but they're not applicable here, are they?

Answer 1

Using NativeKeyEvent.getKeyText() and then comparing to the String button does the trick but buttons then have to be stored as Strings which is okay:

public boolean isPressed(NativeKeyEvent keyEvent)
{
    val modifiers = keyEvent.getModifiers();
    val isModifierPressed = modifiers == modifier;

    if (!isModifierPressed)
    {
        return false;
    }

    val keyCode = keyEvent.getKeyCode();
    val keyText = NativeKeyEvent.getKeyText(keyCode);
    return keyText.equals(this.keyText);
}

Note: val is from Lombok.
