Hierarchical checked tree control with tri-state checkboxes in wxPython?

Question

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.

Answer 1

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.

# TODO List
#
# Almost All The Features Of wx.TreeCtrl Are Available, And There Is Practically
# No Limit In What Could Be Added To This Class. The First Things That Comes
# To My Mind Are:
#
# 1. Implement The Style TR_EXTENDED (I Have Never Used It, But It May Be Useful).
#
# 2. Add Support For 3-State CheckBoxes (Is That Really Useful?).
