Show advertising window

[jano_alex_es]

Hi, in my app I need to show sometimes an advertising window on the bottom-right corner of the screen.

It should appear becoming opaque (from transparent), and dissapear becoming transparent.

Does it have Qt something specific? so far I'm creating a QWidget (Qt::Popup), but I don't find something like the transparency I'm looking for.

Any idea how I can solve it?

thanks!
