Currently only "KDE" or "GNOME" are 77supported and the code uses the X11 session protocol vendor name 78to figure out, which desktop environment is running. The method 79returns an empty string otherwise and on all other platforms. 80 81\membersection{wxAppTraits::GetStandardPaths}\label{wxapptraitsgetstandardpaths} 82 83\func{virtual wxStandardPaths \&}{GetStandardPaths}{\void} 84 85Returns the wxStandardPaths object for the application. 86It's normally the same for wxBase and wxGUI except in the case of wxMac and wxCocoa. 87 88\membersection{wxAppTraits::GetToolkitVersion}\label{wxapptraitsgettoolkitversion} 89 90\func{virtual wxPortId}{GetToolkitVersion}{\param{int *}{major = NULL}, \param{int *}{minor = NULL}} 91 92Returns the wxWidgets port ID used by the running program and eventually 93fills the given pointers with the values of the major and minor digits 94of the native toolkit currently used. 95The version numbers returned are thus detected at run-time and not compile-time 96(except when this is not possible e.g. wxMotif). 97 98E.g. if your program is using wxGTK port this function will return wxPORT\_GTK and 99put in given pointers the versions of the GTK library in use. 100 101See \helpref{wxPlatformInfo}{wxplatforminfo} for more details. 102 103 104\membersection{wxAppTraits::HasStderr}\label{wxapptraitshasstderr} 105 106\func{virtual bool}{HasStderr}{\void} 107 108Returns \true if {\tt fprintf(stderr)} goes somewhere, \false otherwise. 109 110 111\membersection{wxAppTraits::IsUsingUniversalWidgets}\label{wxapptraitsisusinguniversalwidgets} 112 113\constfunc{bool}{IsUsingUniversalWidgets}{\void} 114 115Returns \true if the library was built as wxUniversal. Always returns 116\false for wxBase-only apps. 117 118 119\membersection{wxAppTraits::ShowAssertDialog}\label{wxapptraitsshowassertdialog} 120 121\func{virtual bool}{ShowAssertDialog}{\param{const wxString \&}{ msg}} 122 123Shows the assert dialog with the specified message in GUI mode or just prints 124the string to stderr in console mode. 125 126Returns \true to suppress subsequent asserts, \false to continue as before. 127 128
