    so in this loop

      for(int x = topLeft.x(); x < maxX; ++x) {
        for(int y = topLeft.y(); y < maxY; ++y) {
    

    i can include

    QLabel *label = new QLabel(this);
          foreach( QRgb key, Costs.keys() ) {
            QColor BaseColor( key );
            if (Costs.contains( colour.rgb() ) || IsCloseColor(BaseColor, colour) )  {
              CostInfo& ci = Costs[colour.rgb()];
    //          int Cost = ci.Cost;
              QPixmap pix( ci.ImageName );
    					QPixmap scaledPix = pix.scaled(   8, 8,
    																				 Qt::KeepAspectRatio,
    																				 Qt::SmoothTransformation
    																				 );
    
    ui->label->setPixmap(pix);
    

    ?

    yes something like that.
    if pix is the FINISHED result. seems not.

    That code would just show the original one?

    and why new the qlabel? Why not just add to UI file with designer?

      Because it will not return only one picture, if my picture is 540540 and my rectangle is 88 i cannot just add a label to display 70 picture.

      at the end it will have http://www.hostingpics.net/viewer.php?id=354728program.png

      by replacing all the rectangle by a picture, it depends the color of the rectangle

        @ambershark Lol

        I prefer learn instead of just don't understand what i'm doing, i know i'm very bad to programmation by now but maybe in few years i'il be like mrjj haha !

        for the QPoint, i use it here :

        void MainWindow::on_push2_clicked()
        {
        
        
        	for (int i=0;i<pixi.width();i+=z){
        						 for (int j=0;j<pixi.height();j+=z){
        							 k=k+0.06;
        							Remplissage(pixi,QPoint(i,j),QSize(z,z),Couleurdominante(pixi,QPoint(i,j),QSize(z,z)));
        
        		}
        	}
        
        

        but i use the QPixmap scaledPix .....
        in my function

        void Remplissage(QImage& image, const QPoint& topLeft, const QSize& rectangle, const QColor& colour) {
        

        so it tell that j and i was not declared in this scope

        so i declared i and j in my .h

        #ifndef MAINWINDOW_H
        #define MAINWINDOW_H
        
        #include <QMainWindow>
        #include <QPixmap>
        #include <QPoint>
        #include <QSize>
        #include <iostream>
        #include <QMapIterator>
        #include <QMap>
        
        namespace Ui {
        class MainWindow;
        }
        
        struct CostInfo {
          QString ImageName;
          int     Cost;
        };
        
        int j;
        int i;
        
        class MainWindow : public QMainWindow {
          Q_OBJECT
        
         public:
          explicit MainWindow(QWidget* parent = 0);
        
          ~MainWindow();
        
         private slots:
          void on_push_clicked();
          void on_push2_clicked();
          void on_verticalSlider_sliderMoved(int position);
        
         private:
          Ui::MainWindow* ui;
          QImage pixi;
          QPixmap pixa;
          float k;
          int a;
        
        
          int z = 1;
          int b;
        };
        
        #endif // MAINWINDOW_HH
        
        

        it will work?

        //

        it tell that painter was not declared too, so i search to the QPainter class,

        it's "void QPainter::drawPixmap(const QPoint & point, const QPixmap & pixmap)" that i should use ?

        Haha it's good that you are learning instead of asking for it done like a lot of people on these forums. And hey we all started out bad, don't worry you'll be good in no time if you stick with it. ;)

        I was just quite impressed with the number of posts in this topic.

              I tried something without you (sorry ahah)

              QLabel abc;
              abc.setPixmap(scaledPix);
              abc.show();
              
              

              it compiles but there is a error : QPixmap::scaled: Pixmap is a null pixmap

                scaledPix

                Sounds like scaledPix is not initialize as it should , which often
                comes from not being able to load a file.

                Make sure the image you are scaling, is indeed valid. (loaded)

                  Before posting, i've tried to just

                  QPixmap pix(":/img/ballebleue.png")
                  ui->setPixmap .....
                  

                  and it works

                  u said "scaledPix is not initialize as it should ?"

                    @Payx

                    Yes That would make the pix valid.

                    To get the error " Pixmap is a null pixmap" for scaledPix means that
                    it was not valid. It was empty. so if it came from a scale function, it means
                    that the image u scaled to get scaledPix was empty.

                    Happy new Year :)

                      i have this :

                      so the error come from "QPixmap pix" who is empty

                      so the line "QPixmap pix( ci.ImageName );" dont create a pixmap from my QMap ?

                        That would be my guess yes.

                        You can check pix with isNull()

                          Same error as before "QPixmap::scaled: Pixmap is a null pixmap"

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

                            if (pix.isNull()){

                            };

                            Well that would not really change anything as you create a new local pix and its not related to the "pix" outside
                            You should find out if its invalid and then why it is

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

                                Yes this means that the pictures in the table cannot be loaded.
                                Are they in a resource ?

                                    Oh, they are under IMG

                                    Right click one image file.
                                    Find Get Path
                                    should be something like

                                    :/IMG/filename.xxx

                                    Fix the names in the table.
                                    As far as i recall they start like ":/filename.xxx" and that dont match.

                                    alt text

                                    Note: Here i do NOT have them in a sub folder like you have (img) so path is :/p1.png

                                        oh, it seems correct. You checked they are truly correct?

                                        Please qDebug() << ci.ImageName to verify the variable contains the path from
                                        the table.

                                        just above where you try to make pixmap

                                        qDebug() << "check me--->" << ci.ImageName;
                                        QPixmap pix( ci.ImageName );

                                          I have

                                          check me---> ""
                                          

                                          so there is nothing

                                          i declared as QString ImageName
                                          so maybe it is that ?
