    yes but i can't know exactly, thats why i put 100.

    The things i want its the minimum of all the value

    like a function who calcule all diffBlue+diffRed+diffGreen
    and return me the minimum

      It said that CostInfo, Costs are not declared

        Maybe you use it above where you define it or maybe u didnt show it how CostInfo is defined.

          I defined my QMap here :

          QMap<QRgb, CostInfo > Costs = {
          	{ QColor(255 , 0 , 0 ).rgb(), { "://fraise.png", 10 }},
          	{ QColor(0 , 255 , 0 ).rgb(), { "://balleverte.png", 20 }},
          	{ QColor(0 , 0 , 255 ).rgb(), { "://ballebleue.png", 20 }},
          	{ QColor(255 , 255 , 255 ).rgb(), { "://balleblanche.png", 20 }},
          	{ QColor(255 , 128 , 0 ).rgb(), { "://ballepeche.png", 20 }},
          	{ QColor(0 , 0 , 0 ).rgb(), { "://noir.png", 20 }},
          	{ QColor(102 , 51 , 0 ).rgb(), { "://marron.png", 20 }},
          	{ QColor(255 , 102 , 78 ).rgb(), { "://rose.png", 20 }},
          	{ QColor(0 , 204 , 204 ).rgb(), { "://turquoise.png", 20 }},
          	{ QColor(255 , 178 , 102 ).rgb(), { "://beige.png", 20 }},
          	{ QColor(76 , 0 , 153 ).rgb(), { "://violet.png", 20 }},
          	{ QColor(100 , 100 , 100 ).rgb(), { "://gris.png", 20 }},
          };
          

          And this is a function call no ?

          QMapIterator<QRgb, CostInfo>i;

                the compiler only knows the fundamental types or types defined.
                so you need to define CostInfo or compiler will give you an error.

                    in your case, one of the value you give is { "://fraise.png", 10 }, which is composed of a string and a integer

                    it seems CostInfo should look like this

                    struct CostInfo
                    {
                      QString imageName;
                      int     cost;
                    };

                      Okay understood how it works now.

                      Why it say that "Costs" is not declared, it is the name of the QMap right ?

                            Yes that is how you declare an empty QMap called Costs.

                                CostInfo must be declared before you use it in QMap
                                Where is it?
                                you used to have struct CostInfo declaration.

                                        it sounds right.

                                        The CostInfo is in .h ?

                                        Can you show it ?

                                          #ifndef MAINWINDOW_H
                                          #define MAINWINDOW_H
                                          
                                          #include <QMainWindow>

                                          namespace Ui {
                                          	class MainWindow;
                                          }
                                          
                                          class MainWindow : public QMainWindow

                                          	~MainWindow();

                                          	Ui::MainWindow *ui;
                                          	QImage pixi;
                                          	QPixmap pixa;
                                          	float k;

                                          	int z=1;
                                          	int b;
                                          };
                                          
                                          #endif // MAINWINDOW_H
                                          

                                          and now i remember that i have to paste in the .h but not in public or private so i have :

                                          	int b;

                                          #endif // MAINWINDOW_H
                                          

                                          and what is this line :

                                          QMapIterator<QRgb, CostInfo> i;
                                          

                                          because it say "no matching function to call"
