The advance() function moves all TQCanvasItem::animated() canvas items and setAdvancePeriod() makes TQCanvas move them automatically on a periodic basis. In the context of the TQCanvas classes, to `animate' a canvas item is to set it in motion, i.e. using TQCanvasItem::setVelocity(). Animation of a canvas item itself, i.e. items which change over time, is enabled by calling TQCanvasSprite::setFrameAnimation(), or more generally by subclassing and reimplementing TQCanvasItem::advance().
