PyShell Hangs

wxPython Users

I’m sure this is another newbie question, but why does my PyShell in this
example just hang and refuse

to accept input?

`import string

import wx

import wx.py as py

class MyFrame(wx.Frame):

def __init__(self, parent, ID, title):

    wx.Frame.__init__(self,

parent, ID, title,

wx.DefaultPosition, wx.Size(640, 480))

    self.CreateStatusBar()

    self.SetStatusText("This

is the statusbar")

    menu = wx.Menu()

    menu.Append(wx.ID_EXIT,

“E&xit”, “Terminate the program”)

    menuBar = wx.MenuBar()

    menuBar.Append(menu,

“&File”);

self.SetMenuBar(menuBar)

    wx.EVT_MENU(self,

wx.ID_EXIT, self.TimeToQuit)

def TimeToQuit(self, event):

    self.Close(True)

class MyPanel(wx.Panel):

def __init__(self, parent, id):

    wx.Panel.__init__(self,

parent, id)

sizer=wx.BoxSizer(wx.VERTICAL)

self.shell=py.shell.Shell(parent, -1, introText=“A
PyShell”)

sizer.Add(self.shell,1,wx.EXPAND)

self.SetSizerAndFit(sizer)

class MyApp(wx.App):

def OnInit(self):

    self.frame = MyFrame(None, -1,

“Test”)

    self.panel =

MyPanel(self.frame, -1)

    self.frame.Show(True)

self.SetTopWindow(self.frame)

    return True

app = MyApp(None)

app.MainLoop(`

Change 'parent' to 'self' in this line

  self.shell=py.shell.Shell(parent, -1, introText="A PyShell")

and that makes the program work on our system**.
