RE: What is this JComponent?

[Xiao Wei]

Thanks Greg Munt and Vikram Kumar. Because I am new to Java Swing and don't have any idea on how to design custom UI delegate to a subclass of JButton, could you give me some detailed info on this? Thanks. -----Original Message----- From: Greg Munt [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 02, 2002 1:35 AM To: Vikram Kumar Cc: Xiao Wei; [EMAIL PROTECTED] Subject: Re: What is this JComponent? It depends. If you are absolutely never going to use more than one look and feel, overriding paint() is adequate (although I would prefer to assign a custom UI delegate to a subclass of JButton).   If your application requires the ability to support multiple look and feels, you have three choices:   1. Implement a custom UI delegate for each supported look and feel. This allows the behaviour to vary with the look and feel.   2. Do as above (override paint() or provide a single custom UI delegate) - this will ensure that some behaviours of your components do not vary with the look and feel, but is less time-consuming to implement - especially if the number of look and feels you need to support is large.   3. Implement your own look and feel, which provides this new behaviour for JButtons. This new look and feel could extend another already in existence, such as Metal. ----- Original Message ----- From: Vikram Kumar To: Greg Munt Cc: Xiao Wei ; [EMAIL PROTECTED] Sent: Tuesday, October 01, 2002 11:24 AM Subject: Re: What is this JComponent? in that case what coulf be the solution Greg Munt wrote: That's the AWT way of doing things.

Yes, you are right we can have a button which has icon at top and text at bottom. But how can I implement that when I first click on it, the background color of the text is changed(only getting focus, not fire an event) and click again, then fire one event?   Thanks. -----Original Message----- From: Vikram Kumar [mailto:[EMAIL PROTECTED]] Sent: Tuesday, October 01, 2002 11:02 AM To: Xiao Wei Cc: [EMAIL PROTECTED] Subject: Re: What is this JComponent? Yeah .. They are simple JButtons.. whose icon can be set for normal , mouseOver and mousePressed mode.
