- The wxApp class represents the application itself. It is used to:
-
- @li set and get application-wide properties;
- @li implement the windowing system message or event loop;
- @li initiate application processing via wxApp::OnInit;
- @li allow default processing of events not handled by other
- objects in the application.
+ This class is essential for writing console-only or hybrid apps without
+ having to define wxUSE_GUI=0.
- You should use the macro IMPLEMENT_APP(appClass) in your application
- implementation file to tell wxWidgets how to create an instance of your
- application class.
-
- Use DECLARE_APP(appClass) in a header file if you want the wxGetApp function
- (which returns a reference to your application object) to be visible to other
- files.
