[Jscroll-developer] upgrading JDesktopPane to JScrollDesktopPane

[Philippe C. <pf...@st...>]

Hello,

I have tryed to replace my JDesktopPane for a JScrollDesktopPane in an 
existing application. I found a few problems:

1. JScrollDesktopPane does not subclass JDesktopPane which makes it 
relatively painful to replace because all declaration have to be 
changed. It would be a lot easier if I could have just changed the call 
to the constructor.

2. JScrollDesktopPane does not subclass the JLayeredPane. It also does 
not support the creation of JInternalFrame on different layers. My 
Application uses the PALETTE_LAYER to show floating tool bars.

3. Some components attached to the JScrollInternalFrame do not serialize 
using XMLEncoder. RootToggleButton and RootRadioButtonMenuItem throw 
InstantiationExceptions probably because they do not have no-argument 
constructors.

4. JScrollDesktopPane does not seem to respect the type of the Internal 
Frames you feed it. If I make a subclass of JInternalFrame called 
MyInternalFrame, add it to the desktop and then I call getAllFrames(), I 
will not get a MyInternalFrame back but a JScrollInternalFrame.

For all these reason, I can't use the JDesktopScrollPane with my current 
application (even though I really want to).

Do you think these changes are difficult to make? I would like to get 
involved. How should I proceed? Checkout the cvs and send patches?
