What is the best way to create your beautiful tray notification?

Question

Qt

I need to create a beautiful pop-up cloud from the tray. Of course, the standard QSystemTrayIcon is not suitable for this. The best option is if someone recommends a cross-platform library with such a widget.
Maybe someone had to do such a feature?

Answer 1

I had to, I did it as a window without a frame, I calculated the position of the appearance from the coordinates of QSystemTrayIcon.
And that's how everyone does it.
But everyone makes a mistake, they don’t check whether that window is active in the OS by a timer, because of this, sometimes it doesn’t hide on click on other windows and you have to “click back”.
