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

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
