@class wxAppConsole
This class is essential for writing console-only or hybrid apps without
- having to define wxUSE_GUI=0.
+ having to define @c wxUSE_GUI=0.
+
+ It is used to:
+ @li set and get application-wide properties (see wxAppConsole::CreateTraits
+ and wxAppConsole::SetXXX functions)
+ @li implement the windowing system message or event loop: events in fact are
+ supported even in console-mode applications (see wxAppConsole::HandleEvent
+ and wxAppConsole::ProcessPendingEvents);
+ @li initiate application processing via wxApp::OnInit;
+ @li allow default processing of events not handled by other
+ objects in the application (see wxAppConsole::FilterEvent)
+ @li implement Apple-specific event handlers (see wxAppConsole::MacXXX functions)
+
+ You should use the macro wxIMPLEMENT_APP(appClass) in your application
+ implementation file to tell wxWidgets how to create an instance of your
+ application class.
- @todo MORE INFO
+ Use wxDECLARE_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.

+ Use this macro to disable all debugging code in release build when not
+ using wxIMPLEMENT_APP().
+
+ Currently this macro disables assert checking and debug and trace level
+ logging messages in release build (i.e. when @c NDEBUG is defined). It is
+ used by wxIMPLEMENT_APP() macro so you only need to use it explicitly if you
+ don't use this macro but initialize wxWidgets directly (e.g. calls
+ wxEntry() or wxEntryStart() itself).
+
+ If you do not want to disable debugging code even in release build of your
+ application, you can use wxSetDefaultAssertHandler() and
+ wxLog::SetLogLevel() with @c wxLOG_Max parameter to enable assertions and
+ debug logging respectively.
