As per the title, is this possible?
By tri-state, I mean the parent node is:
- Checked if all children are checked
- Unchecked if all children are unchecked
- Grey/Filled if some children are checked
I have used them previously in C# but cannot find an equivalent control/implementation for wxPython.
Did you look at wx.lib.agw.CustomTreeCtrl?
I’m not sure it does tri-state out of the box, but it’s written in Python, so it should be quite easy to extend it.
