This control is very primitive, however, so it's probably better to use compiler directives and use the wxIE or wxMozilla controls.
In order for your application to have the Windows XP look and feel, you need to create 'appname.exe.manifest' file for your application.
The simplest way is to copy "wxWidgets/bin/widgets.exe.manifest" to your app's directory and rename it to "yourappname.exe.manifest". Finally, modify lines 9 and 10 appropriately - this should work on any Win32 app that does not already have the XP look and feel.
wxWindows 2.5.x or newer
The wx.rc file includes the appropriate manifest, so XP theming will "just work".
