How to change a GTK tree view style in Python?

Question

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?

Answer 1

you need to create a custom CellRenderers for this. the below links might help.

Answer 2

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
