Sorry for den langsome respons, men har haft travlt med alt muligt andet. Jeg er gået over til at bruge qt i stedet for MFC. Og bliver i stedet laver jeg en app til linux, egentlig bare for at lære lidt c++ og bruge QT framework. Jeg er igang med at lave en spillekort klasse, den er langt fra færdig og der mangler en masse, men prøv at se bort fra det. Jeg prøver at lave klassen sådan at jeg kan oprette et kort objekt fra min widget af, og kalde en display(posX,posY,sizeWidth,sizeHeight) funktion, som tager position og størrelsen som billedet skal være. Men synes jeg har lidt svært ved at komme igang, jeg har copy pastet noget kode som jeg har fundet og sat ind. Men det er ikke gjort rigtigt. Kan du lave den show funktion? Og er det den rigtige måde at lave det på?
