    label is not obligatory, it's just me with my few knowlegde that i said i can use labels.

    but the problem is that i have to replace the color by the picture (replace or add) and its here that i'm blocked

        yes each cell is an image.

        on the picture that you showed there is 16 cell so 16 picture who depend on the color

        Edit : we had before "image.setPixelColor(x, y, colour);"

        can't we have like image.'setImage' or something?

          i find a method for display my image or pix (i think) but i'm blocked with the scene ... tell me if i'm in the right direction

            @Payx
            this is what I think before
            I think we can make a method like setImage by scaling the origin image and then set the pixel according to the image that is read

            and I'll read your code
            by the way, can you modify your indentation? I find it's hard to read your code with too many tabs, I need to scroll from left to right.

              here my code.

              My original image is already scaled with

              	for (int i = 0; i < pixi.width(); i += z) {
              		for (int j = 0; j < pixi.height(); j += z) {
              

              so i just add one function to replace rectangle of color by the picture who correspond to this color

                here my code.

                My original image is already scaled with

                	for (int i = 0; i < pixi.width(); i += z) {
                		for (int j = 0; j < pixi.height(); j += z) {
                

                so i just add one function to replace rectangle of color by the picture who correspond to this color

                @Payx
                so where is the scene? I don't find any declaration.
                and I don't find a way to convert a QGraphicsScene to a QImage

                I have two directions

                1. if you want to use the QGraphicsScene, then you don't need to convert it into a image. just use the scene to show your image, and you can read Graphics View Framework to see how to use it.
                2. just copy the scaledPix pixel by pixel to the image

                  i put my .h to see where i declared my scene

                  #ifndef MAINWINDOW_H

                    you can use the debug mode to find out which line of code makes it crash.

                    and I find that you declare two scene, one in the MainWindow, one is global, and you did not use the scene in the MainWindow.
