<p>You can access it using <a class="el" href="classwx_app_console.html#a75ed8ce022a4ca58785f14f736853e93" title="Returns a pointer to the wxAppTraits object for the application.">wxApp::GetTraits()</a> function and you can create your own <a class="el" href="classwx_app_traits.html" title="The wxAppTraits class defines various configurable aspects of a wxApp.">wxAppTraits</a> overriding the <a class="el" href="classwx_app_console.html#ab2811644bfee7a93d0564a09397c4408" title="Creates the wxAppTraits object when GetTraits() needs it for the first time.">wxApp::CreateTraits()</a> function.</p>
<p>Note that <a class="el" href="classwx_app_traits.html" title="The wxAppTraits class defines various configurable aspects of a wxApp.">wxAppTraits</a> is an abstract class since it contains many pure virtual functions. In fact, by default, wxWidgets creates a <code>wxConsoleAppTraits</code> object for console applications (i.e. those applications linked against wxBase library only - see the <a class="el" href="page_libs.html">Library List</a> page) and a <code>wxGUIAppTraits</code> object for GUI applications. Both these classes are derived by <a class="el" href="classwx_app_traits.html" title="The wxAppTraits class defines various configurable aspects of a wxApp.">wxAppTraits</a> and represent concrete implementation of the <a class="el" href="classwx_app_traits.html" title="The wxAppTraits class defines various configurable aspects of a wxApp.">wxAppTraits</a> interface.</p>
