Detailed Description
The wxAppTraits class defines various configurable aspects of a wxApp.
You can access it using wxApp::GetTraits() function and you can create your own wxAppTraits overriding the wxApp::CreateTraits() function.
Note that wxAppTraits is an abstract class since it contains many pure virtual functions. In fact, by default, wxWidgets creates a wxConsoleAppTraits object for console applications (i.e. those applications linked against wxBase library only - see the Library List page) and a wxGUIAppTraits object for GUI applications. Both these classes are derived by wxAppTraits and represent concrete implementation of the wxAppTraits interface.

Member Function Documentation
|
virtual |
Called by wxWidgets to create the default configuration object for the application.
The default version creates a registry-based wxRegConfig class under MSW and wxFileConfig under all other platforms.
The wxApp::GetAppName and wxApp::GetVendorName methods are used to determine the registry key or file name.
|
pure virtual |
Used by wxWidgets to create the main event loop used by wxApp::OnRun().
The default implementation of this method in wxGUIAppTraits returns the usual platform-specific GUI event loop. The version in wxConsoleAppTraits returns a console-specific event loop which can be used to handle timer and socket events in console programs under Unix and MSW or NULL under the other platforms where console event loops are not supported yet.

pure virtual |
Creates the global object used for printing out messages.
|
pure virtual |
Returns the renderer to use for drawing the generic controls (return value may be NULL in which case the default renderer for the current platform is used); this is used in GUI mode only and always returns NULL in console.
- Note
- the returned pointer needs to be deleted by the caller.
|
pure virtual |
This method returns the name of the desktop environment currently running in a Unix desktop.
Currently only "KDE" or "GNOME" are supported and the code uses the X11 session protocol vendor name to figure out, which desktop environment is running. The method returns an empty string otherwise and on all other platforms.
|
virtual |
Returns the wxStandardPaths object for the application.
It's normally the same for wxBase and wxGUI except in the case of wxMac and wxCocoa.
- Note
- The returned reference is to a
wxStandardPathsBaseclass but you can consider it to be equivalent to wxStandardPaths (which is documented).
|
pure virtual |
Returns the wxWidgets port ID used by the running program and eventually fills the given pointers with the values of the major and minor digits of the native toolkit currently used.
The version numbers returned are thus detected at run-time and not compile-time (except when this is not possible e.g. wxMotif).
E.g. if your program is using wxGTK port this function will return wxPORT_GTK and put in given pointers the versions of the GTK library in use. See wxPlatformInfo for more details.

pure virtual |
Returns true if fprintf(stderr) goes somewhere, false otherwise.
|
pure virtual |
Returns true if the library was built as wxUniversal.
Always returns false for wxBase-only apps.
|
pure virtual |
Shows the assert dialog with the specified message in GUI mode or just prints the string to stderr in console mode.
Returns true to suppress subsequent asserts, false to continue as before.
