[news.eclipse.tools.gef] checkbox in GEF treeview

[Al Major <alnospammajor@xxxxxxxxxxxxxxxxxx>]

i already have an outline view using the GEF infrastructure. i'd like to 
be able to place a checkbox (just before the icon) on some of the tree 
items.

an alternative may be some kind of combination tree/table with a column 
for a checkbox.

anyone have a quick outline on how to do this? or better still, a 
pointer to code that does something similar?

regards,

al
