      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.

                  @Payx
                  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 Costs is the QMap variable.

                          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 ?

                                        i think i fixed it i had :

                                        #ifndef MAINWINDOW_H
                                        #define MAINWINDOW_H

                                        #include <iostream>
                                        
                                        namespace Ui {
                                        	class MainWindow;
                                        }
                                        
                                        class MainWindow : public QMainWindow

                                        private slots:
                                        	void on_push_clicked();

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

                                        #endif // MAINWINDOW_H
                                        

                                        and what is this line :

                                        QMapIterator<QRgb, CostInfo> i;
                                        

                                        because it say "no matching function to call"

                                          I wonder if you dont have c++11 compiler.

                                          "no matching function to call"
                                          Make sure you have included QMapIterator
