Hello,
Another thing, here i tried changing self.frame_1 to
guithread.frame_1, so that that part of the code now reads:-

import wx,gui,threading
class guithread(threading.Thread):
    def run(self):
        app = wx.PySimpleApp(0)
        wx.InitAllImageHandlers()
        guithread.frame_1 = gui.MyFrame(None, -1, "")
        app.SetTopWindow(guithread.frame_1)
        guithread.frame_1.Show()
        app.MainLoop()
gui1=guithread()
gui1.start()
class changer(threading.Thread):
    def run(self):
        gui1.frame_1.text_ctrl_1.Setvalue("hello")
chang=changer()
chang.start()

I still get guithread object has no attribute frame_1. I must be doing
something wrong
