Java final keyword

Wikipedia has a great article on the subject so there is no need to re-state it:

http://en.wikipedia.org/wiki/Final_(Java)

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();

   }

   @Override

   protected void onDetach()

   {

      if (saveButton != null)

     saveButton.click();

   }

 }

HTML: superScript

ChicagoMarathon<font size=-2>^Inc</font> ChicagoMarathon ^Inc

HTML: adding bullets

To add an .html bullets, insert below code to get a circle bullets: Circles: <ul><li type=circle>First element <li type=circle>Second element <li type=circle>Third element</ul>

• First element
• Second element
• Third element

If you need square shaped bullets, insert below code: <ul><li type=square>First element <li type=square>Second element <li type=square>Third element </ul>

• First element
• Second element
• Third element
