Why doesn't my Qt Creator know QPolygon?
Frage
I have the following simple code. I just start writing my application and get stuck on this problem: Qt Creator tells me, that QPolygon file or directory doesn't exists. I checked it with QT Documentation and it says, ther is.
#include <QPolygon>
class IHledani
{
public:
virtual IHledani();
virtual ~IHledani();
virtual QPolygon najdiKonturu(IObraz image, int startx, int starty);
};
Thank you
