I am trying to have a Tree in an expanbarwidget. User should be able to scroll through the tree elements using a slider.
I wrote following code for the same



Whlie debuggin I put a breakpoint inside slider-listener.
Message says- "tree" cannot be resolved.
However if I try this on a text box instead of tree everything works fine.
Any suggestions ?
Thanks for reading my question .

Hi Its working now ..just shifted some code outside the listener.

<Control[] children= tree.getChildren(); int count=children.length;
int newSel=count*slide.getSelection()/100;>
 
It is sorta covered in the JavaRanch Style Guide.
