wxPython – Two step creation wx.TreeCtrl

In this article we are going to learn that how can we create a Tree Control using two step creation. In order to do that we will use Create() method in wx.TreeCtrl class. Basically, we will initialize tree control using TreeCtrl() constructor with empty paranthesis and then we will use Create() method and attributes to associate with Tree Control.


wx.TreeCtrl.Create(self, parent, id=ID_ANY, pos=DefaultPosition, size=DefaultSize, style=TR_DEFAULT_STYLE, validator=DefaultValidator, name=TreeCtrlNameStr)


Parameter Type Description
parent wx.Window parent window/frame for Tree Control.
id wx.WindowID widget identifier to be associated with Tree Control
pos wx.Point position where to put Tree Control.
size wx.Size size of the Tree Control widget
style long style for Tree Control.
validator wx.Validator Validator associated withTree Control.
name string Name of Tree Control.

Code Example:






import wx
class TreePanel(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent)
        # initialize Tree Control
        self.tree = wx.TreeCtrl(self, wx.ID_ANY, wx.DefaultPosition, (100, 70),
        # create Tree Control using Create() method
        # Add root to Tree Control
        self.root = self.tree.AddRoot('Root')
        # Add item to root
        itm = self.tree.AppendItem(self.root, 'Item')
        # Add item to 'itm'
        self.tree.AppendItem(itm, "Sub Item")
        # Expand whole tree
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(self.tree, 0, wx.EXPAND)
class MainFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, parent = None, title ='TreeCtrl Demo')
        panel = TreePanel(self)
if __name__ == '__main__':
    app = wx.App(redirect = False)
    frame = MainFrame()
