    Before posting, i've tried to just

    QPixmap pix(":/img/ballebleue.png")
    ui->setPixmap .....
    

    and it works

    u said "scaledPix is not initialize as it should ?"

    EDIT : Happy New Year !

    Yes That would make the pix valid.

    To get the error " Pixmap is a null pixmap" for scaledPix means that
    it was not valid. It was empty. so if it came from a scale function, it means
    that the image u scaled to get scaledPix was empty.

    Happy new Year :)

      					QLabel abc;
      //          int Cost = ci.Cost;
      					QPixmap pix( ci.ImageName );
      					QPixmap scaledPix = pix.scaled(   8, 8,
      																				 Qt::KeepAspectRatio,
      																				 Qt::SmoothTransformation
      																				 );
      					abc.setPixmap(scaledPix);
      					abc.show();
      
      

      i have this :

      so the error come from "QPixmap pix" who is empty

      so the line "QPixmap pix( ci.ImageName );" dont create a pixmap from my QMap ?

        That would be my guess yes.

        You can check pix with isNull()

          So i add the if :

          					if (pix.isNull()){
          					QPixmap pix(":/img/ballebleue.png");
          					};
          
          

          Same error as before "QPixmap::scaled: Pixmap is a null pixmap"

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

            if (pix.isNull()){
            QPixmap pix(":/img/ballebleue.png");
            };

            Well that would not really change anything as you create a new local pix and its not related to the "pix" outside
            You should find out if its invalid and then why it is

            if (pix.isNull()){
            qDebug() << "yep its no good";
            return;
            };

                Yes this means that the pictures in the table cannot be loaded.
                Are they in a resource ?

                    Oh, they are under IMG

                    Right click one image file.
                    Find Get Path
                    should be something like

                    :/IMG/filename.xxx

                    Fix the names in the table.
                    As far as i recall they start like ":/filename.xxx" and that dont match.

                    alt text

                    Note: Here i do NOT have them in a sub folder like you have (img) so path is :/p1.png

                        oh, it seems correct. You checked they are truly correct?

                        Please qDebug() << ci.ImageName to verify the variable contains the path from
                        the table.

                        just above where you try to make pixmap

                        qDebug() << "check me--->" << ci.ImageName;
                        QPixmap pix( ci.ImageName );

                          check me---> ""
                          

                          so there is nothing

                          i declared as QString ImageName
                          so maybe it is that ?

                            Not sure. check the code that look it up.
                            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.

                                        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.
