Windows taskbar deskband

[mrjigsaw]

Hello.

I want to make a binary clock in Windows taskbar. I have managed to hide the clock by changing the registry and refreshing the process explorer.exe.
Now I have to add my binary clock to taskbar. The only way that I found is by deskbands.

I found out that to modify the taskbar you can use QtWinExtras. But I can't see any deskband class here.
Is it even possible to write this binary clock using Qt? I couldn't find any code that would do that.

I'm using Windows 10 if that matters.
