QPixmap videoplaylistQPixmap("/home/owen/code/video_playlist/png/background/background4.png");
videoplaylistQPixmap = videoplaylistQPixmap.scaled(QSize(900,580), Qt::IgnoreAspectRatio, Qt::SmoothTransformation );
QPalette videoplaylistPalette;
videoplaylistPalette.setBrush(QPalette::Background, QBrush(videoplaylistQPixmap));
playlistTreeWidget->setPalette(videoplaylistPalette);

这么设定背景可以吗，怎么没反应。
