[Qt-interest] [QtS60-feedback] Qt Qbrush issue

[Ramesh]

Hi, christen,,

"it gives nothing" means, it will not give any color only..

I found solution for the problem.. too. It is.. 

QBrush::QBrush ()
Constructs a default black brush with the style Qt::NoBrush (i.e. this brush
will not fill shapes).

I have to set the style of the QBrush object by setStyle(), for example with
Qt::SolidPattern.

Fix for my problem

QGraphicsScene * scence = new QGraphicsScene();
   QBrush *brush = new QBrush();
   brush->setStyle(Qt:SolidPattern); // Fix your problem !
   brush->setColor(QColor(60,20,20));
   scence->setBackgroundBrush(*brush);

   QGraphicsView *view = new QGraphicsView();
   view->setScene(scence);
   //view->setBackgroundBrush(*brush);
   //view->setCacheMode(QGraphicsView::CacheBackground);
   view->showFullScreen();

I don't think there should be any difference. With "it gives nothing",
do you mean that you get a transparent background?
