These classes enable developers to take advantage + of native services while still using a cross-platform API. + + \annotatedlist desktop + + \section1 Setting the Application Icon + + In order to change the icon of the executable application file + itself, as it is presented on the desktop (i.e., prior to + application execution), it is necessary to employ another, + platform-dependent technique. + + \tableofcontents {1 Setting the Application Icon} + + \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. + + \section1 Desktop Widgets + + On systems where the user's desktop is displayed using more than one screen, + certain types of applications may need to obtain information about the + configuration of the user's workspace to ensure that new windows and dialogs + are opened in appropriate locations. + + The QDesktopWidget class can be used to monitor the positions of widgets and + notify applications about changes to the way the desktop is split over the + available screens. This enables applications to implement policies for + positioning new windows so that, for example, they do not distract a user + who is working on a specific task. +*/ |
