Re: Control on Tree Row collapsing

["Ashwin Ramachandran" <rashwin28 gmail com>]

Thanks Torsten. That was the signal that I was looking for.

Moreover, in such a case, I also want to know, whether the collapse of a row, has happened
on the parent which holds the selected tree item. Foreg:
+ ABC
 - 123
+ DEF
 -456. < --- selected.

When 456 is selected and ABC is collapsed, I do not want to throw any confirmation dialog.
When 456 is selected and only in case DEF [or its parent] is collapsed, I want to throw the confirmation.

With the signal for tree-collapse-row, I can now get the path and iter of the row collapsed.
but how do I use that information to get information on whether that path[ie DEF] is the parent
or parent's parent for 456[Assuming I have information pertaining to the iter and path of 456].

Is there any direct API to verify that?

I checked ancestor and descendant, but both do not seem to work.
[i can always manipulate the path string to verify my requirement on whether it is a parent
or not, but I just wanted to check if there is already an API available to do that].

Thanks
Ashwin

Sounds like you want the "test-collapse-row" signal on the
Gtk2::TreeView:
