    Move the foreach loop in the else part. There's no sense in looping through the whole map if it contains colour.rgb(). Also note that you won't see any QLabel since it's going out of scope.

        I'd guess it doesn't compile.

        Your BaseColor variable doesn't make sense where it's declared. The if (IsCloseColor... also doesn't make sense where you put it. You are searching the map to find which of its key is close to the colour you received. But currently if BaseColor fits you are just trying to show each and every element of Costs.

        Again: your QLable objects will be destroyed before they are even shown.

          Yes but i dont want to display one picture so the label is here just for display the picture from my QMap my final picture with all the QMap's image is display in the label_3

          sorry but i loose you ^^

          the if (IsClose .. doesnt make sense ? i put it after the else because if the bool dont return true we can't continue no?

          ""BaseColor fits you are just trying to show each and every element of Costs.""
          so maybe replace "foreach( QRgb key, Costs.keys() )" by just "foreach(only the image)" can i write ImageName.key ?

            @Payx
            I think what @SGaist says is that

            if Costs contains colour.rgb() you can do what you want
            else you should go though the Costs to search if there is a BaseColor that is close to colour
            and if there is one, you can do what you want

            what you do now is
            if Costs contains colour.rgb() you do what you want
            else test if BaseColor is close to colour
            if it is then you go though the Costs and do what you want

            the difference is that
            you are not search for a BaseColor that is close to colour( which is a foreach then if )
            but test if BaseColor is close to colour and go though the Costs( which is a if then foreach )
            and the BaseColor is unknown since there is no key defined before it

              its what i did no ?

              EDIT : it tell me that key isnt declared in QColor BaseColor( key );

                No, what you are doing is that if colour is close to base colour you loop on your map.

                What you want to do is loop on the map and if any of the colour ÌsCloseColour` then use that one.

                As for the build error, look where you declared key and where you are currently using it.

                  Sorry if i don't understand well but """IsCloseColor(BaseColor, colour) == true""" dont mean that if any of the color IsCloreColour ?

                    No, that function checks the whether the colours passed as parameters are close.

                    What you want to do is check which one of the map entries is close to the reference.

                    Take a look at your code and the order in which you wrote it. You are not testing the content of the Costs map, you are just checking whether colour is close to BaseColor which currently you can't create since your key variable is inside your loop and not outside where you declared BaseColor.

                      Ok,

                      					foreach( QRgb key, Costs.keys() ) {
                      					QColor BaseColor( key );
                      					if (IsCloseColor(BaseColor, colour) == true){
                      

                      so first i loop on my map, i declare my BaseColor who is the color in my map, and i check if it's close to my color's reference, right ?

                        Looks better, yes.

                        Don't forget to break out of the loop once you found a match.

                            Because you are still trying to get the wrong entry from your map. If you enter your foreach loop, it means that colour can't be found in your map thus you can't use it to get the value from the map.

                            IsCloseColor tells you that BaseColor and colour are close, then you must use key to get the CostInfo you want.

                              Ok i understand, so it doesnt work because i still search my color in my map.

                              So i have to replace color by basecolor (when IsCloseColor(BaseColor, colour) == true) right ? and search for basecolor in my map ?

                                    yes

                                    by the way, you don't need to write if( IsCloseColor( BaseColor , colour ) == true ) explicitly. Yout can write if( IsColseColor( BaseColor , colour ) ) since the return value of IsCloseColor is already a bool and if can test it

                                        Again checkout what you get, whether what it contains is valid.

                                        And again 2, you are creating QLabels that will be destroyed before they can be shown.

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

                                          And again 2, you are creating QLabels that will be destroyed before they can be shown.

                                          So maybe write "QLabel abc;" in my .h ?

                                          Again checkout what you get, whether what it contains is valid.

                                          i have

                                          						CostInfo& ci = Costs[BaseColor.rgb()];
                                          						QPixmap pix( ci.ImageName );
                                          

                                          Maybe i don't understand well this 2 lines, i explain what i understand and tell me if i'm wrong.

                                          The first line put in my variable ci the "line" referent to my BaseColor ( it stock the Costs (who have a QString and a Int))

                                          the second line create a pixmap from the ImageName referent to my BaseColor. So something like (QPixmap pix(:/img/ballepeche.png))
