hello,
I am using checkboxtreeviewer in my application. I want it to behave like
other checkbox trees in Eclipse IDE. When user checks parent checkbox, all
its child item checkboxes should get checked, if any child item is
checked, its parent item should get grayed and when all the child items
are checked then parent should get automatically checked and so on.

I thought this feature should be available ready made in
checkboxtreeviewer, but sadly, its not :(

can you help me have above mentioned functionality?

Thanks in advance,
Amay.

I think you want ContainerCheckedTreeViewer?
