    \ingroup buildsystem
    \ingroup deployment

    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 \c{#ifdef} directives (see below).

    Qt provides a few low-level global functions for fine-tuning
    applications on specific platforms. See \l{Special-Purpose Global
    Functions Exported by Qt} for details.

    For information about which platforms are supported by Qt, see the
    \l{Platform Notes}. For information on distributing Qt applications, see
    \l{Deploying Qt Applications}.

    \target x11
    \section1 Qt/X11

    When compiling for this platform, the macro \c{Q_WS_X11} is defined.

    \note You must compile with XRender support to get alpha transparency
    support for pixmaps and images.
