Hi,

Do you mean you have a two dimensional array of chars that you want to build a grid with and that each of the cell of that grid shall contain the letter at that point of the array ?

From what you posted, there's nothing added to the scene and your view seems to be a local variable so unless it's in your main function body, it will be destroyed before you can even see it.

@SGaist but before i destroying it i have to handle that i want to save my array(inside there are my chars) as a QtPiximap -> after that i can show it in GraphisScene ?

[SGaist]

Except that you are not using your array to draw anything. You are using a QBitArray which contains nothing to draw on a image that you then use as brush.

You should start by just drawing on that QImage properly and set it on a QLabel to see what it would look like. And once you have that working, come back to your QGraphicsView part.
