Hi,

how can I retrieve the icons [+] and [-] of a Tree?
I want to implement my own tree widget, but I wish to use the same icons.

Thanks
Enrico

Enrico,

these images reside in the org.eclipse.rap.rwt.q07 plug-in. E.g.
resources/widgets/rap/tree/plus.gif. Thus you should be able to get
a reference like this:
String name = "resources/widgets/rap/tree/plus.gif";
ClassLoader loader = RWT.class.getClassLoader();
Graphics.getImage( name, loader );

*BUT* with doing so you access implementation details that may
change without advance notice.

Thank you very much!

Hi Enrico,

I'm just curious - what are you trying to achieve? Do you want to
implement your own tree widget? If so, what are the reasons for such an
investment?

Cheers and thanks in advance
Benny

Hi Benny,

the current Tree widget implemented in RAP consumes too much memory in
IE 7. I need to load thousands of items so the Tree is unusable for me.

I've re-implemented my own tree widget using a Table widget with [+] and
[-] icons and spaces to show indentation. This implementation is fast
and memory-saver!

Bye
Enrico
