Hi,
I dispose a Tree in runtime and then create a new one but the new one is
not displayed.

What I am doing wrong?

my code is something like this;
tree.dispose();
tree = new Tree(parent, SWT.SINGLE);

thanks,
aiQa

Your new Tree will have size 0,0 unless you either:
- invoke layout() on the parent Composite (assuming that the parent
Composite uses a layout)
- invoke setSize() on the Tree (if the parent Composite does not use a
layout)
