      @Payx
      I think you can output the imageName in the foreach to check if there is a file name.

      and you can try to use debug mode and execute step by step to find out which line cause the problem.

      maybe it will be more clear what's wrong with it.

        Hi
        Yes as @Flotisable says, you should check what is going on with the file name

        so

        xxxx
        QPixmap pix( ci.ImageName );
        qDebug() << "image i get from ci.ImageName : " << ci.ImageName;

        and see what it really is.

            Ok so path is good ? seems ok.
            So I guess it does load it there. ( in pix)
            But why does

            if (pix.isNull()){
            qDebug() << "yep its no good";
            return;
            };

            still trigger then ?

            or is that from
            if (IsCloseColor(BaseColor, colour) == true){
            xxx
            }
            else {
            qDebug() << "yep its no good";
            }

            ?

                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:

                    a label in my UI the picture will just be displayed in the same label no ?

                    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

                                  on top of the "red" image ? so that each cell is an image?

                                    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?

                                        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
