    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 ?

                            i think i fixed it i had :

                            #ifndef MAINWINDOW_H
                            #define MAINWINDOW_H
                            
                            #include <QMainWindow>
                            #include <QPixmap>

                            }
                            
                            class MainWindow : public QMainWindow
                            {
                            	Q_OBJECT
                            
                            public:

                            	struct CostInfo

                            	~MainWindow();

                            private:
                            	Ui::MainWindow *ui;
                            	QImage pixi;
                            	QPixmap pixa;

                            };
                            
                            #endif // MAINWINDOW_H
                            

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

                            #ifndef MAINWINDOW_H

                            	int     cost;
                            };
                            
                            
                            class MainWindow : public QMainWindow

                            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

                                  Ok. No sure what goes wrongly for you. Seems to have CostInfo
                                  in .h and Costs QMap in cpp which should be fine.

                                  • How can i see if i have a c++ compiler ?
                                    c++11 compiler. Meaning a compiler that knows the new c++11 version.
                                    I assume you do. But if you are on linux or using old Qt it might not be the case.

                                  So what platform and Qt version?

                                      It looks ok.
                                      What is the exact error you get?

                                      Also 4.1 is very old. Are you using old mingw too?

                                      Old compilers might not like the initialisation list/in place
                                      If you just do
                                      QMap<QRgb, CostInfo > Costs;

                                      Will it compile then?

                                          QMapIterator<QRgb, CostInfo> i; is wrong

                                          It should be something like

                                          QMap<QRgb, CostInfo>::const_iterator i = Costs.constBegin();
                                          while (i.hasNext()) {
                                          //etc.
                                          }
