◆ infoForFrame()

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.

◆ next()

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.

int QMoviePrivate::speedAdjustedDelay ( int delay ) const

Given the original delay, this function returns the actual number of milliseconds to delay according to the current speed. E.g. if the speed is 200%, the result will be half of the original delay.
