The final keyword is especially important when you write a lot of asynchronous code (GWT), or write complex subclassing.
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;}
GWT: Auto-saving a TextArea
You can use this inner class:
private class TextAreaAutoSave extends TextArea{public TextAreaAutoSave(){super();}@Overrideprotected void onDetach(){if (saveButton != null)saveButton.click();}}
