        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 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 ?

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

                                  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

                                      How can i see if i have a c++ compiler ?

                                        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?
