Re: Swing on Palm OS or Win CE
Check out a company called savaJe (pronounced savage). They offer a J2SE version for various ARM platforms like the iPAQ. You can run Swing based programs then on the devices.

Re: What is the difference between paint() and paintComponent()?
Not exactly sure what you are asking for here If you want to create your own lightweight component, or customize the behavior of an existing one... in your subclass of JComponent, override paintComponent() to make sure things like the component's border are displayed. If you don't, and override paint() instead, then the methods paintComponent, paintBorder, and paintChildren won't be called, as that is what default paint() version does, ensuring each is given the appropriate drawing area. If you want to create your own heavyweight component, subclass Canvas and override paint(). If there is no UI delegate in Swing, you essentially don't have a component. It really needs one... You can also create your own UI delegate if you don't like the behavior of a component. At 04:41 AM 5/28/2001 -0400, D. Michael Nelson wrote: So far, this is what I have figured out, which is not much.(Graphic Java Mastering the JFC Vol II: Swing p.138) What is the difference between paint() and paintComponent()? The Jcomponent.paint() method actually delegates the work of painting to three protected methods: paintComponent, paintBorder, and paintChildren. They're called in the order listed to ensure that children appear on top of component itself. If the UI delegate is non-null (what if it is null?), Jcomponent.paintComponent() invokes the delegate's update() method, which clears the background for opaque components and subsequently paints the components. I think I am missing the big picture. Please, share any knowledg or resources you may have on this topic!

Re: memory leak... some one help, please!!
You don't null out tempString between calls to append() so it keeps
growing. A StringBuffer is probably your better data structure, but it too
would need to be emptied between calls.

RE: memory leak... some one help, please!!
That I don't know, but I did notice that tempString is kept set between
calls. And THAT isn't necessary. I'm not quite sure why the variable is an
instance variable. It seems only used within the method. I'd change the
variable scope, too.
