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

The AppTraits class defines various configurable aspects of a App.
Called by wxWidgets to create the default configuration object for the application.
The default version creates a registry-based RegConfig class under MSW and FileConfig under all other platforms.
The App.GetAppName and App.GetVendorName methods are used to determine the registry key or file name.
Return type: | ConfigBase |

Used by wxWidgets to create the main event loop used by App.OnRun .
The default implementation of this method in GUIAppTraits returns the usual platform-specific GUI event loop. The version in ConsoleAppTraits returns a console-specific event loop which can be used to handle timer and socket events in console programs under Unix and MSW or None under the other platforms where console event loops are not supported yet.
Return type: | EventLoopBase |
---|
Creates a Log class for the application to use for logging errors.
The default implementation returns a new LogGui class.
Return type: | Log |

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.
Return type: | string |

Returns the StandardPaths object for the application.
It’s normally the same for Base and GUI except in the case of Mac and Cocoa.
Return type: | StandardPaths |

Note
The returned reference is to a StandardPathsBase class but you can consider it to be equivalent to StandardPaths (which is documented).
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. Motif).
E.g. if your program is using wxGTK port this function will return PORT_GTK and put in given pointers the versions of the GTK library in use. See PlatformInfo for more details.

Returns True if fprintf(stderr) goes somewhere, False otherwise.

Returns True if the library was built as wxUniversal.
Always returns False for Base-only apps.
Return type: | bool |

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.
Parameters: | msg (string) – |
