Window System Specific Notes
Qt is a cross-platform GUI toolkit, so almost the entire API is the same on all platforms and window systems. If you wish to use platform-specific features, and still maintain a platform-independent source tree, you should protect the platform-specific code using the appropriate #ifdef
directives (see below).
Qt provides a few low-level global functions for fine-tuning applications on specific platforms. See Platform-Specific Functions for details.
For information about which platforms are supported by Qt, see the Platform and Compiler Notes. For information on distributing Qt applications, see Deploying Qt Applications.
Qt for X11
When compiling for this platform, the macro Q_WS_X11
is defined.
Not documented here. Please contact Qt's technical support team if you have queries.
See the Qt for X11 Requirements page for more information about the libraries required to build Qt with as many features as possible.
Qt for Windows
When compiling for this platform, the macro Q_WS_WIN
is defined.
Not documented here. Please contact Qt's technical support team if you have queries.
Qt for Mac OS X
When compiling for this platform, the macro Q_WS_MAC
is defined.
Qt for Embedded Linux
When compiling for this platform, the macro Q_WS_QWS
is defined (the window system is literally the Qt Window System). See the Qt for Embedded Linux documentation for more information.
Qt for Windows CE
When compiling for this platform, the macro Q_WS_WINCE
is defined. See the Qt for Windows CE documentation for more information.
Qt for the Symbian platform
When compiling for this platform, the macro Q_WS_S60
is defined. See the The Symbian platform - Introduction to Qt documentation for more information.
