As the title of my question may be sufficiently understandable, I'll explain anyway.
I'm working on a personal project with Electron, and I'm facing a frustrating issue which is :
I'd like to create a small window (50x50 px) which would be above every other window, even when those are fullscreen. I mean, even if I'm on Youtube with Chrome and I enter fullscreen, my window would stay on top of it.
Basically, I've succeeded in making my window above all the others, a simple setAlwaysOnTop(true) did the trick. However, the taskbar in Windows keeps showing, but if I hide my window or just close it, the taskbar disappears and everything's fine.
So my question is : How can I achieve to have a window above all the others, including fullscreen ones, which wouldn't make the taskbar visible ? (in my sense, the taskbar kills the fullscreen end-user experience).
Details : my window has transparency enabled, and both kiosk mode and fullscreen mode are not needed since I only use 50x50 px.
Thank you for your help.
