GWT: Override StackPanel onBroswerEvent()

An inner class is a customized class that is used inside a java class. The main purpose of inner class is to use a generic method that may be problematic to use in the actual class. This is a useful concept when using when using onBrowserEvent(Event event) method for instance in google web toolkit because I could not initialize an event in the original java class. Below are the step t implement this:

- Create a private inner class StackPanelNav  that extends the container/super class StackPanel:

private class StackPanelNav extends StackPanel

    {

public StackPanelNav()

{

    super();

}

@Override

public void onBrowserEvent(Event event)

{

    super.onBrowserEvent(event);

    switch (this.getSelectedIndex())

    {

    case 0:

    {

        // Handle selected

    }

break;

}
