[SOLVED] In Lwuit, How to handle Keypad navigation Events?

In Lwuit, How to handle Keypad navigation Events?

In the application I'm building I have Tabs and a list in for each Tab. the behavior I want is when I press the Left/Right Nav Key the selected Tab will change. when I press the Up/Down Nav Key the List will change selection index.

I used LWUIT GUI builder to generate StateMachine/StateMachineBase class.

I've been trying to fix this all day. please help.

Solution

Pheromix's answer is correct but he didn't account for the UIBuilder. To override the Form creation in the UIBuilder override the method:

protected Component createComponentInstance(String componentType, Class cls) {
    if(cls == com.sun.lwuit.Form.class) {
        return new MyFormSubclass();
    }
    return super.createComponentInstance(componentType, cls);
}

There is an option to override the Tab selection behavior but to get the most accurate behavior this might be the best approach.
