No, the QT TreeView is far better than the msVB one. And the way I implemented 
it is just different because I wanted to avoid creating useless objects for 
each tree node. Try to fill a treeview with thousands of nodes in Vb and in 
Gambas, and then compare.

Thsi is true. But when you use .Current, then the internal pointer is moved to 
the current node.

It works like that!

I really don't understand your point.

Gambas thinks are not exactly like VB things! :-)
