<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>The <a href="qsystemtrayicon.html">QSystemTrayIcon</a> class provides an icon for an application in the system tray.</p>
<p>Modern operating systems usually provide a special area on the desktop, called the <i>system tray</i> or <i>notification area</i>, where long-running applications can display icons and short messages.</p>
<p class="centerAlign"><img src="images/system-tray.png" alt="The system tray on Windows XP." /></p><p>The <a href="qsystemtrayicon.html">QSystemTrayIcon</a> class can be used on the following platforms:</p>
<ul>
<li>All supported versions of Windows.</li>
<li>All window managers and independent tray implementations for X11 that implement the <a href="http://standards.freedesktop.org/systemtray-spec/systemtray-spec-0.2.html freedesktop.org">http://standards.freedesktop.org/systemtray-spec/systemtray-spec-0.2.html freedesktop.org</a> XEmbed system tray specification.</li>
<li>All X11 desktop environments that implement the D-Bus <a href="http://www.freedesktop.org/wiki/Specifications/StatusNotifierItem/StatusNotifierItem">http://www.freedesktop.org/wiki/Specifications/StatusNotifierItem/StatusNotifierItem</a> specification, including recent versions of KDE and Unity.</li>
<li>All supported versions of macOS.</li>
</ul>
<p>To check whether a system tray is present on the user's desktop, call the <a href="qsystemtrayicon.html#isSystemTrayAvailable">QSystemTrayIcon::isSystemTrayAvailable</a>() static function.</p>
<p>To add a system tray entry, create a <a href="qsystemtrayicon.html">QSystemTrayIcon</a> object, call <a href="qsystemtrayicon.html#setContextMenu">setContextMenu</a>() to provide a context menu for the icon, and call <a href="qsystemtrayicon.html#show">show</a>() to make it visible in the system tray. Status notification messages ("balloon messages") can be displayed at any time using <a href="qsystemtrayicon.html#showMessage">showMessage</a>().</p>
<p>If the system tray is unavailable when a system tray icon is constructed, but becomes available later, <a href="qsystemtrayicon.html">QSystemTrayIcon</a> will automatically add an entry for the application in the system tray if the icon is <a href="qsystemtrayicon.html#visible-prop">visible</a>.</p>
<p>The <a href="qsystemtrayicon.html#activated">activated</a>() signal is emitted when the user activates the icon.</p>
<p>Only on X11, when a tooltip is requested, the <a href="qsystemtrayicon.html">QSystemTrayIcon</a> receives a <a href="../qtgui/qhelpevent.html">QHelpEvent</a> of type <a href="../qtcore/qevent.html#Type-enum">QEvent::ToolTip</a>. Additionally, the <a href="qsystemtrayicon.html">QSystemTrayIcon</a> receives wheel events of type <a href="../qtcore/qevent.html#Type-enum">QEvent::Wheel</a>. These are not supported on any other platform.</p>
