Most of the wxPython toolkit is accessed through the
wx package which you
access using the
import wx statement. Every wxPython program must have
an application object—an instance of a
wx.App subclass that defines an
OnInit() method. Most wxPython programs will have one or more
frames—instances of subclasses of
wx.Frame. A frame is the large, movable,
resizeable window-like container that appears on screen, often with a menu,
status bar, tool bars, and other widgets. Control of your program passes to
wxPython when you call your application’s
MainLoop() method.
