    u said "do a list", instead of write ...<100, we can do a "for" and "return" the minimal "diffBlue+diffRed+diffGreen" or the all color no ?

    @Payx If you want to return the closest color from a list then you need to write a function similar to IsCloseColor. You iterate over the list, calculate the diff and store the color with the smallest diff and its diff in local variables, then return the color from that local variable.

        No sure what "browse a list is"

            QList<QColor> ColorList;
            ColorList << QColor(100,100,100) << QColor(200,200,200) << QColor(0,0,100) ;
            for( int c=0; c < ColorList.size();c++ ) {
            QColor CurCol=ColorList[c]; // take from list
            // ... do what u want
            }

          like compare all the color with a for

          you said it to me ^^

          @Payx
          No. use a list (of colors) and loop over it, checking each.

          i already have this (you give it to me)

          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 }},
          };
          
          bool IsCloseColor( QColor c1, QColor c2 ) {
          	int diffRed   = Math.abs(c1.red() - c2.red());
          	int diffGreen = Math.abs(c1.green() - c2.green());
          	int diffBlue  = Math.abs(c1.blue()  - c2.blue());
          
          	if (diffBlue+diffRed+diffGreen< 100){	/
          		return true;.
          		else
          				return false;
          
          
          	}
          }
          

          the function i want to create is to browse the Qmap and pick the color who got the minimum ""diffBlue+diffRed+diffGreen< 100""

            Hi
            ok. i see. we had the code higher up.

            Qcolor colour; // the one you compare too. set to something...
            QMapIterator<QRgb, CostInfo >i(Costs);
            while (i.hasNext()) {
            i.next();
            QColor BaseColor( i.key() ); // the color in table
            if (Costs.contains( colour.rgb() ) || IsCloseColor(BaseColor, colour) ) { // directly have colour or it is < 100
            //// we got a match
            }
            }// while

              Okay,

              but we keep the code ?

              because the <100 isn't good, you said we have to compare all the colors and see what colors match the best

                Yes ?
                Then change the 100.
                Its just a value. You should examine your color and see
                the value for color that you consider "The same"
                Maybe its need to be 80 or 110. Depends on how close
                the color must be for you to think its the same.

                  Yes, but correct me if i'm wrong, it could be possible that it detect many colors under 100 right ?

                    its a value. How high or low u need it to be , depends
                    on your application.

                      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 Costs is the QMap variable.
