Unsolved Window arrangement RPI with fullscreen camera view

[Alexsc]

Hello!
i am just starting out with Qt and well, its been hard to really know if i can do what i want to, mostly because i usually learn by reading examples and i honestly haven't found anything i could use as a base for my app.

So i guess i have two questions:
1.- Is it true that all cameras are equal to Qt?
2.- Is it possible to run a camera view, in full screen, no borders with a button on a corner to be the settings?
and how would this be done? I just need that example/piece of code to do everything else.

Now here is my reason why, i am cross compiling an app on a RPI, i will be using a raspi cam (Not really but a sensor connected to a 22 pin adapter), a custom case and lenses to make a specialized industrial camera which will do things like pattern recognition and so on. I can code the function, i already have that one done on Python, which is probably how ill be leaving them, but i am honestly such a noob with Qt that it hurts, so any help would be appreciated.

Hi and welcome to devnet,

1. As long as they are all equal for the platform backend in case of Linux GStreamer
2. So a QVideoWidget with a floating QPushButton ?
