Member Function Documentation
[signal] void QPlatformSystemTrayIcon::activated(QPlatformSystemTrayIcon::ActivationReason reason)
This signal is emitted when the user activates the system tray icon. reason specifies the reason for activation.
See also QSystemTrayIcon::ActivationReason.
[pure virtual] void QPlatformSystemTrayIcon::cleanup()
This method is called to cleanup the platform dependent implementation.
[virtual] QPlatformMenu * QPlatformSystemTrayIcon::createMenu() const
This method is called in case there is no QPlatformMenu available when updating the menu. This allows the abstraction to provide a menu for the system tray icon even if normally a non-native menu is used.
The default implementation returns a null pointer.
This function was introduced in Qt 5.3.
See also updateMenu().
[pure virtual] QRect QPlatformSystemTrayIcon::geometry() const
This method returns the geometry of the platform dependent system tray icon on the screen.
[pure virtual] void QPlatformSystemTrayIcon::init()
This method is called to initialize the platform dependent implementation.
[pure virtual] bool QPlatformSystemTrayIcon::isSystemTrayAvailable() const
Returns true if the system tray is available on the platform.
[signal] void QPlatformSystemTrayIcon::messageClicked()
This signal is emitted when the message displayed using showMessage() was clicked by the user.

See also QSystemTrayIcon::showMessage().
[pure virtual] bool QPlatformSystemTrayIcon::supportsMessages() const
Returns true if the system tray supports messages on the platform.
[pure virtual] void QPlatformSystemTrayIcon::updateIcon(const QIcon & icon)
