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 native windowing system main message or event loop, and to dispatch events to window instances
- etc.
Every wx application must have a single 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), however wx.App is also usable on it’s own without derivation.
__init__ | Construct a wx.App object. |
MainLoop | Execute the main GUI event loop |
OnPreInit | Things that must be done after _BootstrapApp has done its thing, but |
RedirectStdio | Redirect sys.stdout and sys.stderr to a file or a popup window. |

Note
You should override OnInit to do application initialization to ensure that the system, toolkit and wxWidgets are fully initialized.
Execute the main GUI event loop
Things that must be done after _BootstrapApp has done its thing, but would be nice if they were already done by the time that OnInit is called. This can be overridden in derived classes, but be sure to call this method from there.
Redirect sys.stdout and sys.stderr to a file or a popup window.
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.
Set the “main” top level window, which will be used for the parent of the on-demand output window as well as for dialogs that do not have an explicit parent set.
