- QmlTimeLine tl; - tl.move(v, 100., 200); - tl.start() - \endcode - - If your program needs to know when values are changed, it can either - connect to the QmlTimeLine's updated() signal, or inherit from QmlTimeLineValue - and reimplement the QmlTimeLineValue::setValue() method. - - \i Supports multiple QmlTimeLineValue, arbitrary start and end values and allows - animations to be strung together for more complex effects. - - For example, the following animation moves the x and y coordinates of - an object from wherever they are to the position (100, 100) in 50 - milliseconds and then further animates them to (100, 200) in 50 - milliseconds: - - \code - QmlTimeLineValue x(<starting value>);
