wxPYTHON CHOICE LIST DIALOG

REVISED: REVISED: Sunday, March 3, 2013

In this tutorial, you will learn how to create a wxPython choice list dialog box.

I. wxPYTHON CHOICE LIST DIALOG BOX

When the program starts the choice list dialog box is displayed. When the user selects a color and clicks OK the "choice list dialog box" is destroyed and the users color selection is printed on the open Python Shell window. When the user clicks Cancel, the "choice list dialog box" is destroyed and the Python Shell window remains open.

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. Use four spaces, columns, for each indent.

import wx

if __name__=='__main__':

# Creates application object named app
        app=wx.PySimpleApp()

# Python list named colorList, first color is 0, second color is 1; etc.
  colorList=['blue', 'green', 'orange', 'purple', 'red', 'violet', 'yellow']

# Creates list dialog box object named color
# Four parameters:
# 1. Parent name is None
# 2. User prompt, is "What is your lucky color?"
# 3. List dialog box title, is "LUCKY COLORS"
# 4. Python list is named colorList
  color=wx.SingleChoiceDialog(None, "What is your lucky color?", "LUCKY COLORS", colorList)

# If OK is clicked, uses string variable %s to print their lucky color on Python Shell window
  if color.ShowModal()==wx.ID_OK:
  print "Your lucky color is %s\n" % color.GetStringSelection()

# Destroys list dialog box object named color
  color.Destroy()

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

C:\Python27\brightListDialog.py

From the "New Window", do a "Run" and then a "Run Module F5" and a wxPython GUI toolkit frame with the title "PLAIN FRAME WINDOW" 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 a wxPython choice list dialog box.

wxPYTHON SIMPLE TEXT PROGRAM

REVISED: Sunday, March 3, 2013

In this tutorial, you will learn how to create a wxPython simple text program.

I. wxPYTHON SIMPLE TEXT PROGRAM

A. wxPYTHON "DIALOG BOX" FRAME

A dialog box, text box, is used to prompt the user for information. The text box title, DIALOG BOX, is shown at the top left of the panel. The question the user is to respond to, is show under the text box title. The text box, where the user enters a response, is in the center on the panel. The bottom of the panel has two buttons: OK, and Cancel. If the user clicks Cancel, the user response is not assigned to a variable and the DIALOG BOX frame is closed. If the user clicks OK, the user response is assigned to a variable, and the DIALOG BOX frame is closed.

B. wxPYTHON "FRAME WINDOW" FRAME

When the DIALOG BOX frame closes, the plain FRAME WINDOW opens with the user response displayed.

II. wxPYTHON EXAMPLE PROGRAM

import wx

class bright(wx.Frame):

        def __init__(self,parent,id):
                wx.Frame.__init__(self,parent,id,'PLAIN FRAME WINDOW', size=(600,400))
  panel=wx.Panel(self)

# Creates a dialog box object named box
# Four parameters:
# 1. Parent name is panel
# 2. User prompt, question
# 3. Dialog Box frame title
# 4. Dialog Box default text
  box=wx.TextEntryDialog(panel, 'What color is the White House?','DIALOG BOX FRAME','Enter a color.')

# Stores user response in variable answer, if user clicks OK
answer=" "
                if box.ShowModal()==wx.ID_OK:
                        answer=box.GetValue()

# Writes user input to the PLAIN FRAME WINDOW
# Four parameters:
# 1. Parent name is panel
# 2. ID is -1
# 3. Variable is answer
# 4. Position is 15 across and 20 down from top left corner of PLAIN FRAME WINDOW
  wx.StaticText(panel, -1, answer, (15,20))

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 brightSimpleText.py to the same path which your computer used to download Python 2.7.3. For example, I saved my brightSimpleText.py file to my Python27 folder using the following path:

C:\Python27\brightSimpleText.py

From the "New Window", do a "Run" and then a "Run Module F5" and a wxPython GUI toolkit frame with the title "DIALOG BOX FRAME" 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 a wxPython simple text program.
