Member Function Documentation

◆ activated

void QPlatformSystemTrayIcon::activated ( QPlatformSystemTrayIcon::ActivationReason reason )

signal

This signal is emitted when the user activates the system tray icon.

reason specifies the reason for activation.

See also: QSystemTrayIcon::ActivationReason, contextMenuRequested()

Referenced by QQuickLabsPlatformSystemTrayIcon::QQuickLabsPlatformSystemTrayIcon(), QStatusNotifierItemAdaptor::Activate(), QStatusNotifierItemAdaptor::ContextMenu(), QStatusNotifierItemAdaptor::SecondaryActivate(), and QWindowsSystemTrayIcon::winEvent().

Here is the caller graph for this function:

◆ cleanup()

void QPlatformSystemTrayIcon::cleanup ( )

pure virtual

This method is called to cleanup the platform dependent implementation.

Implemented in QDBusTrayIcon, QWindowsSystemTrayIcon, and QWidgetPlatformSystemTrayIcon.

Referenced by QQuickLabsPlatformSystemTrayIcon::cleanup().

Here is the caller graph for this function:

◆ contextMenuRequested

void QPlatformSystemTrayIcon::contextMenuRequested	(	QPoint	globalPos,
		const QPlatformScreen *	screen
	)

signal

This signal is emitted when the context menu is requested.

In particular, on platforms where createMenu() returns nullptr, its emission will cause QSystemTrayIcon to show a QMenu-based menu.

See also: activated()

Since: 5.10

Referenced by QWindowsSystemTrayIcon::winEvent().

Here is the caller graph for this function:

◆ createMenu()

QPlatformMenu * QPlatformSystemTrayIcon::createMenu ( ) const

virtual

This method allows platforms to use a different QPlatformMenu for system tray menus than what would normally be used for e.g.

menu bars. The default implementation falls back to a platform menu created by the platform theme, which may be null on platforms without native menus.
