Doubts in 40000 chips

[prosass]

Hello everyone,
I´m new to Qt and I was exploring the 40000 chips demo, trying to adapt it to the application I want to build. That app is a map where i can see the objects located in the map.

1) What is the use of x and y in the chip(color, x, y)? Are they coordinates?

2) I tried to use an image as a background image, but tiles show up? Any way to expand the image so it takes up the whole space?

That´s it for the moment, I hope someone can help me.

Regards.

Yes, they are.

Sure, scale the pixmap accordingly before applying it.

Thanks Wysota, but I have an additional question.

I was able to avoid the tiles by using a QPixmap and adding it to the scene. Now my problem is that I want to adapt the image that I use to fit the screen. For example, if the image´s size is several megapixels, I want it to fit in my screen so I don´t have to use the zoom out everytime I load an image. How do I do this?

Thanks in advance and regards.
