The wx.App class represents the application and is used to:
- bootstrap the wxPython system and initialize the underlying
gui toolkit
- set and get application-wide properties
- implement the windowing system main message or event loop,
and to dispatch events to window instances
- etc.
Every application must have a wx.App instance, and all
creation of UI objects should be delayed until after the
wx.App object has been created in order to ensure that the gui
platform and wxWidgets have been fully initialized.
Normally you would derive from this class and implement an
OnInit method that creates a frame and then calls
self.SetTopWindow(frame).
See Also: wx.PySimpleApp
for a simpler app class that can be used
directly.
Method Summary |
|
__init__ (self,

MainLoop (self)
Execute the main GUI event loop |

RedirectStdio (self,
filename)
Redirect sys.stdout and sys.stderr to a file or a popup window. |
|
RestoreStdio(self)
|
|
SetOutputWindowAttributes (self,
title,
pos,
size)
Set the title, position and/or size of the output window if
the stdio has been redirected. |
|
SetTopWindow (self,
frame)
Set the "main" top level window |
__init__(self,
redirect=False,
filename=None,
useBestVisual=False,
clearSigInt=True)
(Constructor)
Construct a wx.App object. -
- Parameters:
redirect -
Should sys.stdout and sys.stderr be
redirected? Defaults to True on Windows and Mac, False
otherwise. If filename is None then output will be
redirected to a window that pops up as needed. (You can
control what kind of window is created for the output by
resetting the class variable outputWindowClass to a
class of your choosing.)
filename -
The name of a file to redirect output to, if
redirect is True.
useBestVisual -
Should the app try to use the best
available visual provided by the system (only relevant on
systems that have more than one visual.) This parameter
must be used instead of calling SetUseBestVisual later
on because it must be set before the underlying GUI
toolkit is initialized.
clearSigInt -
Should SIGINT be cleared? This allows the
app to terminate upon a Ctrl-C in the console like other
GUI apps will.
- Overrides:
wx.PyApp.__init__
Note: You should override OnInit to do applicaition
initialization to ensure that the system, toolkit and
wxWidgets are fully initialized.

RedirectStdio(self,
filename=None)
Redirect sys.stdout and sys.stderr to a file or a popup window. -
|
SetOutputWindowAttributes(self,
title=None,
pos=None,
size=None)
Set the title, position and/or size of the output window if
the stdio has been redirected. This should be called before
any output would cause the output window to be created. -
