Description
It would be useful to check to see if a QPixmap exists without having to copy the pixmap. This is a performance request. During scrolling, I speculatively read thumbnails that are not displayed. If the thumbnails have not been loaded into the pixmap cache, I will then load them.
Checking the pixmap includes the cost of copying the pixmap, which I would like to avoid.
static bool exists(const QString &key);
