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;
}
