Is there a GNU equivalent to MS Hierachialflexgrind control

[Jonas thomas]

Hello all,
I'm sort of a recovering hard-core VB6 programmer who's slowly learning C++ (Current project is to disect Bruce Eckel's "Thinking in C++")
My personal VB6 weapon of choice has been MS Hierachialflexgrind control. Are there any open source object libraries world that remotely resemble what that thing can do??
In particular, I tend to display sql results in the flexgrid and wind up doing all kinds of bizare custom sorts within the flexgrid control using the compare() function that are not very easy to do in sql..
Thanks,
JT

you might be reffering to what the GTK calls a Treeview.

I poked around the net a little... It looks like it might do the trick...
Thanks..
