QT how to detect the systray area for creating systary pop up windows

i need to create/design QT systray popup windows , i was thinking about creating c开发者_StackOverflowustom windows that derived from QDialog , so it could look better then the ordinary "Information,Warning,Critical styles"

my question is how can i detect the position of the desktop systray ,so how could give the popup windows

the look and feel of a systray popup

You might use the rectangle given by QSystemTrayIcon::geometry() to know precisely the position of the desktop systray. The geometry method gives the position in screen coordinate of the system tray icon.

See the documentation for more information.
