\title Desktop Integration
\brief Integrating with the user's desktop environment.
\ingroup best-practices
\ingroup qt-gui-concepts

Qt applications behave well in the user's desktop environment, but certain
integrations require additional, and sometimes platform specific, techniques.
\section1 Useful Classes
Various classes in Qt are designed to help developers integrate applications into
users' desktop environments. These classes enable developers to take advantage
of native services while still using a cross-platform API.

\section1 Opening External Resources
Although Qt provides facilities to handle and display resources, such as
\l{QImageIOHandler}{common image formats} and \l{QTextDocument}{HTML},
it is sometimes necessary to open files and external resources using external
applications.
QDesktopServices provides an interface to services offered by the user's desktop
environment. In particular, the \l{QDesktopServices::}{openUrl()} function is
used to open resources using the appropriate application, which may have been
specifically configured by the user.
\section1 System Tray Icons
Many modern desktop environments feature docks or panels with \e{system trays}
in which applications can install icons. Applications often use system tray icons
to display status information, either by updating the icon itself or by showing
information in "balloon messages". Additionally, many applications provide
pop-up menus that can be accessed via their system tray icons.
The QSystemTrayIcon class exposes all of the above features via an intuitive
Qt-style API that can be used on all desktop platforms.
