    If from table it should not be empty :)

      Are you sure you are retrieving a valid value from your map ?

        No it's sure that it's not a valid value !

        QPixmap pix( ci.ImageName );
        

        so it create a pix from a QString no ? that why it didnt work ?

          From what you wrote before, ci.ImageName is empty, correct ?

          If so, check the key that you use to retrieve the data from the map. If not part of the map, depending on the technique used, you will get a default constructed object.

            Yes it's empty.

            			foreach( QRgb key, Costs.keys() ) {
            				QColor BaseColor( key );
            				if (Costs.contains( colour.rgb() ) || IsCloseColor(BaseColor, colour) )  {
            					CostInfo& ci = Costs[colour.rgb()];
            					QLabel abc;
            //          int Cost = ci.Cost;
            					qDebug() << "check me--->" << ci.ImageName;
            					QPixmap pix( ci.ImageName );
            					if (pix.isNull()){
            					qDebug() << "yep its no good";
            					return;
            					};
            					QPixmap scaledPix = pix.scaled(   8, 8,
            																				 Qt::KeepAspectRatio,
            																				 Qt::SmoothTransformation
            																				 );
            					abc.setPixmap(scaledPix);
            					abc.show();
            

            it's what i have.

              Your logic is flawed. If Costs contains colour.rgb() then you can go on with the rest of your logic else you should go through your map and use IsCloseColor to determine which key is good. Then you can use that key to go further.

                So i have to separate the

                colour.rgb() ) || IsCloseColor(BaseColor, colour)
                

                ?

                can you tell me how can i got through my map i've already search and asked but no one answer

                  You're already doing it with your foreach loop and the documentation of QMap shows several ways of looping through its content.

                      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

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

                                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.

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

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

                                    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.
