QFrameInfo QMoviePrivate::infoForFrame ( int frameNumber)

Returns the QFrameInfo for the given frameNumber.

If the frame number is invalid, an invalid QFrameInfo is returned.

If the end of the animation has been reached, a special end marker QFrameInfo is returned.

bool QMoviePrivate::jumpToNextFrame ( )

◆ next() [1/2]

bool QMoviePrivate::next ( )

Attempts to advance the animation to the next frame. If successful, currentFrameNumber, currentPixmap and nextDelay are updated accordingly, and true is returned. Otherwise, false is returned. When false is returned, isDone() can be called to determine whether the animation ended gracefully or an error occurred when reading the frame.
