Called when a drag has finished.

Parameters
eEvent describing the finish.
mtrue if some movement occurred, otherwise false.

Implements Drag.

◆ motion()

void VideoTimeLineDrag::motion ( GdkEvent e,
bool  f 
)
virtual

Called when a drag motion has occurred.

Parameters
eEvent describing the motion.
ftrue if this is the first movement, otherwise false.

Implements Drag.
