◆ 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.

◆ cleanup()

void QPlatformSystemTrayIcon::cleanup ( )
pure virtual

This method is called to cleanup the platform dependent implementation.

Implemented in QDBusTrayIcon, QWindowsSystemTrayIcon, and QWidgetPlatformSystemTrayIcon.

◆ contextMenuRequested

void QPlatformSystemTrayIcon::contextMenuRequested ( QPoint globalPos,

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.
