QM_Step

QM_Step(areaRef; numFrames):error
	areaRef	Longint	Movie area reference
	numFrames	Longint	Number of frames
	error	Longint	Error result

Instructs the movie controller in a movie plug-in area to step the movie currently assigned to the area, by a number of frames forward or backward.

The movie plug-in area is specified by areaRef.

Parameter numFrames specifies the number of frames to step. Positive values cause the movie to step forward and negative values step the movie backwards. A value of 0 steps the movie forward one frame; a value of 1 has the same effect.

Example

`Step the movie in plug-in area xMovieArea 3 frames backwards

$error:=QM_Step (xMovieArea;-3)
