wxPython window

To open a window with wxPython, run the code below:

#!/usr/bin/python

import wx      
app = wx.App()
frame = wx.Frame(None, -1, 'win.py')
frame.Show()
app.MainLoop()

The line wx.App() creates an application object. Each wx program needs to have one .App() object.

The method wx.Frame() returns a new window which can contain widgets.

app.Mainloop() puts the application in the main loop and listens for events.

Window size and position
You can set the position and size with the SetDimensions() function:

#!/usr/bin/python

import wx

app = wx.App()
frame = wx.Frame(None, -1, 'win.py')
frame.SetDimensions(0,0,640,480)
frame.Show()
app.MainLoop()

The parameters of the function are: x (left), y (top), width and height. The function not only sets the screen resolution but also the position on the screen.

Center a window
To put the window in the center of the screen call:

frame.Centre()
