wxPYTHON MESSAGE DIALOG

REVISED: Sunday, March 3, 2013

In this tutorial, you will learn how to create wxPython message dialog.

I.  wxPYTHON MESSAGE DIALOG

Message dialog is used to get input from the user.

II.  wxPYTHON EXAMPLE PROGRAM

Start the Python 2.7.3 interpreter shell by "double left mouse clicking" the Python icon on your desktop. When the "Python Shell" window opens  select "File", then select "New Window". In the "New Window" type the following code, which is an expansion of the class bright we worked with in the last tutorial.  Use four spaces, columns, for each indent.

import wx

class bright(wx.Frame):

        def __init__(self,parent,id):
                wx.Frame.__init__(self,parent,id,'Bright Message', size=(800,400))
                panel=wx.Panel(self)

# Creates a message dialog object named box
                box=wx.MessageDialog(panel, 'Are you happy?','HAPPY?',wx.YES_NO)

# Creates a variable named answer
# Stores user response in variable answer
                answer=box.ShowModal()

# Box is destroyed after the user response is stored in answer
                box.Destroy()

if __name__=='__main__':
        app=wx.PySimpleApp()
        frame=bright(parent=None,id=-1)
        frame.Show()
        app.MainLoop()

From the "New Window", do a "File Save As" and save the above Python program, using the file name brightMessage.py to the same path which your computer used to download Python 2.7.3. For example, I saved my brightMessage.py  file  to my Python27 folder using the following path:

C:\Python27\brightMessage.py

From the "New Window", do a "Run" and then a "Run Module F5" and a wxPython GUI toolkit frame with the title "HAPPY?" in the top left corner will open.  The comments which start with  a hash, #, sign explain how this wxPython program works. Some of the underscores are double underscores; e.g., __init__,  __name__, and __main__  all have double underscores before and after them.

In this tutorial, you have learned how to create wxPython message dialog.
