hi,all:
i have a tree, a button and a textarea,when i select a treeitem of the
tree and click the button,
what i want is to remove this treeitem from its parent and then iterator
all data carried by those
treeitems left on the tree excepted the removed one.
now i used treeitem.dispose() to let the treeitem is invisible,but i
always get an error when i
immediately iterator the tree:
Unhandled event loop exception
Reason:
Widget is disposed

if i do like this after mouseClicked(MouseEvent e) is invoked,every thing
is ok.

any one can help me?

thanks a lot ahead!
