Insert QRectF into QGraphicsRectItem
-
I have created an instance of QRectF and I want it to a parameter of a QGraphicsRectItem but whe I try to pass it as a parameter the compiler says: Program finished unexpectedly. What am I doing wrong?
QGraphicsRectItem *tempi;QList <QRectF> rectan; QList <QGraphicsRectItem*>draw_rectan;for(int i=0;i<random_numbers_.size();i++){
QRectF temp;
temp.setRect(i*25,0-random_numbers_[i],20,random_numbers_.at(i));
rectan.append(temp);
tempi->setRect(rectan.at(i));
draw_rectan.append(tempi);} for(int i=0;i<random_numbers_.size();i++){ scene->addRect(rectan.at(i),Pen,darkMagentaBrush); }Mandruk1331

most probably because rectan.size() != random_numbers_.size() ?
Since you are using rectan[i]/rectan.at(i) you need to make sure the index is within bounds.--- SUPPORT REQUESTS VIA CHAT WILL BE IGNORED ---

QGraphicsRectItem *tempi = new QGraphicsRectItem;
tempi->setRect(rectan.at(i));
draw_rectan.append(tempi);
I think it was overwriting data
