Hi,

I am trying to force a specific size on a layout item as shown (400x400), but it doesn't work. Is there a way for it?

Thanks

Qt Code: 
  1. #include <QtGui>
  2.  
  3. class LayoutItem : public QGraphicsWidget {
  4. public:
  5.   LayoutItem(QGraphicsItem *parent = 0) : QGraphicsWidget( parent ) {}
  6.   void paint(QPainter *painter, const QStyleOptionGraphicsItem *option,
  7.              QWidget *widget = 0) {
  8.  
  9.     qDebug() << "LayoutItem::paint, size = " << size();
  10.     QRectF frame(QPointF(0,0), geometry().size());
  11.     painter->drawRect( frame );
  12.   }
  13.  
  14. };
  15.  
  16. class Window : public QGraphicsWidget {
  17. public:
  18.   Window(QGraphicsWidget *parent = 0) {
  19.  
  20.     QGraphicsGridLayout *grid = new QGraphicsGridLayout( this );
  21.     LayoutItem* item = new LayoutItem;
  22.     grid->addItem(item, 0, 0, 1, 1);
  23.     item->resize( 400, 400 );
  24.   }
  25. };
  26.  
  27. int main(int argc, char **argv)
  28. {
  29.   QApplication app(argc, argv);
  30.  
  32.  
  33.   Window *window = new Window;
  34.   scene.addItem(window);
  35.   QGraphicsView view(&scene);
  36.   view.resize(500, 500);
  37.   view.show();
  38.  
  39.   return app.exec();
  40. }
