Returns the text box currently used when adding samples to a text track. The text box is the rectangle within the track's bounds where text is drawn.
Parameter movieRef is the reference to the movie instance. The movie reference must have been previously obtained with a call to QM_NewMovieFromFile.
Parameter trackID is the ID of the track.
Parameters boxLeft, boxTop, boxRight and boxBottom receive the coordinates of the text box in the track's coordinate system. If all parameters are equal to -1, the text box is specified by the track's bounds.
QMedia sets the default text box coordinates to {-1, -1, -1, -1}.
Example
`Get the text box of track ID $trackID C_LONGINT($txLeft;$txTop;$txRight;$txBottom) $err:=QM_GetTextMediaBox ($movie;$trackID;txLeft;$txTop;$txRight;$txBottom) |
