Detailed Description#
Modern operating systems usually provide a special area on the desktop, called the system tray or notification area, where long-running applications can display icons and short messages.
The
QSystemTrayIcon
class can be used on the following platforms:All supported versions of Windows.
All Linux desktop environments that implement the D-Bus StatusNotifierItem specification , including KDE, Gnome, Xfce, LXQt, and DDE.
All window managers and independent tray implementations for X11 that implement the freedesktop.org XEmbed system tray specification .
All supported versions of macOS.
To check whether a system tray is present on the user’s desktop, call the
isSystemTrayAvailable()
static function.To add a system tray entry, create a
QSystemTrayIcon
object, callsetContextMenu()
to provide a context menu for the icon, and callshow()
to make it visible in the system tray. Status notification messages (“balloon messages”) can be displayed at any time usingshowMessage()
.If the system tray is unavailable when a system tray icon is constructed, but becomes available later,
QSystemTrayIcon
will automatically add an entry for the application in the system tray if the icon isvisible
.The
activated()
signal is emitted when the user activates the icon.Only on X11, when a tooltip is requested, the
QSystemTrayIcon
receives a QHelpEvent of type QEvent::ToolTip. Additionally, theQSystemTrayIcon
receives wheel events of type QEvent::Wheel. These are not supported on any other platform. Note: Since GNOME Shell version 3.26, not allActivationReason
are supported by the system without shell extensions installed.See also

Properties can be used directly when
from __feature__ import true_property
is used or via accessor functions otherwise.This property holds the system tray icon.
On Windows, the system tray icon size is 16x16; on X11, the preferred size is 22x22. The icon will be scaled to the appropriate size as necessary.
- property toolTipᅟ: str#
This property holds the tooltip for the system tray entry.
On some systems, the tooltip’s length is limited. The tooltip will be truncated if necessary.

Setting this property to true or calling
show()
makes the system tray icon visible; setting this property to false or callinghide()
hides it.- Access functions:
