Auto resize columns in TreeListCtrl

I create a tree control:

self.tree_cat = wx.gizmos.TreeListCtrl(self, -1, style=some-styles)

Then I add columns:

self.tree_cat.AddColumn("blah")
self.tree_cat.AddColumn("blah")

Now how do I make the columns au开发者_如何学JAVAto-resize when I add elements?

The way you should be able do this is to use the wx.lib.mixins.listctrl.ListCtrlAutoWidthMixin as a mixin class for the wx.TreeListCtrl.

But apparently there's a bug with it currently.
