First wxpython program: why doesn't window persist

Simply replace your line:
app = wx.PySimpleApp()
with
app = wx.PySimpleApp(0) # (redirects the output of sys.stderr to the prompt)

You will discover, as I did, that you invoked the file “sample.txt” before you created it :slight_smile:

2008/5/15 Terry Carroll carroll@tjc.com:

wxPython beginner here. I’m trying a very simple wxPython program, to do

nothing more than open a text window displaying text from a small file.

I see the window flash up, but the program terminates. My expectation was that

the window would stay open, and then when I hit the close button, my program

would terminate. Where am I going wrong?

the program:

import wx

class TextFrame(wx.Frame):

def __init__(self, filename):

    wx.Frame.__init__(self, None, -1,

                      title=filename, style=wx.DEFAULT_FRAME_STYLE)

    panel = wx.Panel(self, -1)

    lines = file(filename).readlines()

    tc = wx.TextCtrl(panel, -1, style=wx.TE_MULTILINE)

    for line in lines:

        tc.AppendText(line)

if name == “main”:

filename = "sample.txt"

app = wx.PySimpleApp()

frame = TextFrame(filename)

frame.Show()

app.MainLoop
