Qt Assistant says:
"void QWidget::setPaletteBackgroundPixmap ( const QPixmap & pixmap )
Use the palette directly.
For example, if you have code like
widget->setPaletteBackgroundPixmap(pixmap);
you can rewrite it as
QPalette palette;
palette.setBrush(widget->backgroundRole(), QBrush(pixmap));
widget->setPalette(palette);"
I hope this helps.
