I have an app written in python that presents some of its data in a tree view. By default, the tree view is a floaty white affair with little floaty triangles to expand the nodes.
Is it possible to change this style to be more like a Windows explorer tree view? Specifically, I'd like to have vertical lines indicating parentage of the nodes.
If this is possible, how would it be done?
For lines linking the arrows there is a method in gtk.TreeView for that, see http://library.gnome.org/devel/pygtk/stable/class-gtktreeview.html#method-gtktreeview--set-enable-tree-lines
