wx Python is not properly drawing customtree items

I am currently using wx.CustomTree, to use to display a series of configuration settings. I generally fill them with wx.TextCtrl / wx.Combobox, to allow the user to edit / enter stuff. Here is my code:

class ConfigTree(CT.CustomTreeCtrl):
    """
        Holds all non gui drawing panel stuff
    """
    def __init__(self, parent):
        CT.CustomTreeCtrl.__init__(self, parent,
                                   id = common.ID_CONTROL_SETTINGS,
                                   style = wx.TR_DEFAULT_STYLE | wx.TR_HAS_BUTTONS
                                        | wx.TR_HAS_VARIABLE_ROW_HEIGHT | wx.TR_SINGLE)
        #self.HideWindows()
        #self.RefreshSubtree(self.root)
        self.population_size_ctrl = None
        self.SetSizeHints(350, common.FRAME_SIZE[1])
        self.root = self.AddRoot("Configuration Settings")
        child = self.AppendItem(self.root, "Foo", wnd=wx.TextCtrl(self, wx.ID_ANY, "Lots Of Muffins"))

The problem is, any children nodes, the data for these nodes is not filled in. When i basically expand the configuration settings tree node. I see the "Foo" node, however the textbox is empty. This is the same for both text node, Until i actually click on the child node. I've looked tried every form of update / etc. Doe开发者_如何学Cs anyone have any ideas?

Firstly sorry for not giving the rest of the code. I've gotten around this problem by simply resizing the window everytime i demo the application.

So i tried the code on my Macbook Pro running Mac OS X, with newest wx and python 2.6. I still have the same problem, however i noticed resizing the window, or even touching the scrollbar fixes the issue.

I also noticed however, there is absolutely NO problems running on Windows Vista / Windows 7.

So trying this on another macbook running an older version of wx + python. Results in the same problem :(

Is there anyway to force the panel to redraw it self? Which i am pretty sure happens when i resize the window.

If you don't have any ideas then i'll strip it down and make a demo example, im home and won't be at work until later tommorow.

You can use RefreshItems if you are using virtual controls, or you could refresh the panel, which would update the contents of all the children windows (widgets).

I tested it on window with wx version 2.8.10.1 and it works, which OS and wx version you are using?

here is self contained code, which can be copy-pasted and run

import wx
import wx.lib.customtreectrl as CT

class ConfigTree(CT.CustomTreeCtrl):
    """
        Holds all non gui drawing panel stuff
    """
    def __init__(self, parent):
        CT.CustomTreeCtrl.__init__(self, parent,
                                   id = -1,
                                   style = wx.TR_DEFAULT_STYLE | wx.TR_HAS_BUTTONS
                                        | wx.TR_HAS_VARIABLE_ROW_HEIGHT | wx.TR_SINGLE)
        self.population_size_ctrl = None
        self.SetSizeHints(350, 350)
        self.root = self.AddRoot("Configuration Settings")
        child = self.AppendItem(self.root, "Foo", wnd=wx.TextCtrl(self, wx.ID_ANY, "Lots Of Muffins"))

def main():
    app = wx.App()
    frame = wx.Frame(None, title="Test tree", size=(500,500))
    p = wx.Panel(frame, size=(500,500))
    tree = ConfigTree(p)
    tree.SetSize((500,500))
    frame.Show()
    app.MainLoop()

if __name__ == '__main__':
    main()
