pygtk treeview selection?

[Cirdan7]

What is the best way to get the selected item in a TreeView and get the most out of it. I got it to work where something happens if you click on the item, but when you click it, the selected item doesn't get highlighted. Also, how to I get the actually text of a selected item?

The problem is that your selectCategory function

must return True as under:

def selectCategory(self, selection):
print selection
return True
