Title
Body
I'm trying to paint some points of my image and I don't know why it doesn't work. I have defined a QImage and I want to modify some points. QImage *cou= new QImage(height,largeur,QImage::Format_Mono); cou->fill(1); QPainter *fig=new QPainter (cou); for (i=0;i<size_;i++) { fig-> drawPoint(floor(propa[i]),nbmax[i]); } When I execute the code I obtain QPainter::begin: Paint device returned engine == 0, type: 3 and in the following lines: QPainter::drawPoints: Painter not active
