      Well it seems you just do
      QLabel abc;
      which will not work at all as this label is then deleted as soon as function ends.

      Putting it in .h will help it not getting deleted but its still not connected to the screen in any way.
      If you have UI file. Cant u put it there?
      and get via
      ui->label
      Then its in the right place.

      To do this, you must make Remplissage member of the mainwindow so you can acces its UI

          @Payx said in How to include .txt on Qt:

          Yes. You can add more than one label if u need more pics to be shown at same time.

            my funtion is

            void Remplissage(QImage& image, const QPoint& topLeft, const QSize& rectangle, const QColor& colour) {
            
               int maxX = topLeft.x() + rectangle.width();
               int maxY = topLeft.y() + rectangle.height();
            
               for(int x = topLeft.x(); x < maxX; ++x) {
               	for(int y = topLeft.y(); y < maxY; ++y) {
            

            in

            Remplissage(pixi, QPoint(i, j), QSize(z, z), Couleurdominante(pixi, QPoint(i, j), QSize(z, z)));
            

            so it depends on my z, if i say that my z = 20; and if my picture is 540 * 540 i will need 729 labels lol.

            example :

            here my previous code : http://hpics.li/36d1f82

            my picture is 128 * 128, if my z = 28; it appears 4 colors by 4 colors.

            How can i display a picture by color without add 10000 labels, thats why i though that create a label in my loop will work

              Create a new image and put it into a secondary QLabel.

                Something like :
                QImage from pix
                And put the image into a label ?

                I know that put a label into a loop wont work u told me. But how can i do so ?

                    You lost me on what you are trying with the Labels. 729 ?!?!
                    Do you mean to have the lables like
                    alt text
                    or how would you place all these labels?

                      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

                              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?

                              @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

                                  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

                                      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.
