background color for QGraphicsWidget

[QAir]

Hello all,
I'm trying the following to set background color for a QGrahpicsWidget object



QGrahpicsWidget* w = new QGrahpicsWidget();
QBrush brush;
QPalette palette;
palette = w->palette();
brush.setColor(Qt::blue);
palette.setBrush(QPalette::Active, QPalette::Background, brush);
w->setPalette(palette);


but it doesn't work :(
any one has an idea???
thx to much

I'm afraid this functionality is not supported by QGraphicsWidget. You could file a suggestion to add "autoFillBackground" property like QWidget has.
