Hi,
Now, I use picture slide show in my background app with transaction effect by using QLabel, paintEvent, opacity, Qtimer, QPixmap.
All are ok. Then I add a new function that add a widget and move it with QTimer when I press a key.
But movement is delay during changing the picture's transaction time.
Should I use QGraphicsView instead of QLabel's pixmap for best performance?
Thanks.
