wxPython TreeCtrl

  • Last Updated : 08 Jul, 2020

In this article we are going to learn about and TreeCtrl and how can we add TreeCtrl to our window. A tree control presents information as a hierarchy, with items that may be expanded to show further items. Items in a tree control are referenced by wx.TreeItemId handles, which may be tested for validity by calling wx.TreeItemId.IsOk .

We will use TreeCtrl() constructor to create TreeCtrl.
