I was trying to port a GTK1 app toward a GTK2 app. In my GTK1 app I
was using a CTree and I had to implement a TreeView in my GTK2 app to
show my old tree.
I have two questions:
1) There is a way to set the root of the tree?
e.g:
root
> child 1
> child 2
What I want is: in this example, I could not move the child 1 or the
child 2 to the root position! The root will always be the ROOT of the
tree.
2) There is a way to select when a node will be a leaf or a node?
Thanks,
