Windowsystem-specific Notes


Qt is a cross-platform GUI toolkit, so almost the entire API is the same on all platforms and windowsystems. However some development tasks may require you to write small windowsystem-specific tasks. This page documents the windowsystem-specific parts of the Qt API. Note that any use of these features renders your application non-portable to other Qt-supported windowsystems, so protect such code with appropriate "#ifdef" directives (see below), preferably with code for each platform to which you wish to retain portability.

For information about which platforms are supported by Qt, see the Platform Notes.

Qt/X11

When compiling for this platform, the macro _WS_X11_ is defined.

Not documented here. Please contact Trolltech Technical Support if you have queries.

Qt/Windows

When compiling for this platform, the macro _WS_WIN_ is defined.

Not documented here. Please contact Trolltech Technical Support if you have queries.

Qt/Embedded

When compiling for this platform, the macro _WS_QWS_ is defined (the window system is literally the Qt Window System).
