version 6.0

DR SET DRAW MODE (area; mode)

Parameter	Type		Description
area	Longint		4D Draw area
mode	Integer		0=Edge
			1=Center

The command DR SET DRAW MODE controls whether new objects in area are drawn from their centers or from their edges.

If mode equals 0, objects are drawn from their edges.

If mode equals 1, objects are drawn from their centers.

The default setting is to draw objects from their edges.

The following example is the object method for a check box named bMode. In the Before phase, it determines the drawing mode of Area and sets the check box accordingly. It then allows the user to set the drawing mode by clicking the check box. If the check box is checked, objects in Area are drawn from their centers. If the check box is unchecked, objects are drawn from their edges.

   Case of
      :(Before)
            `If we are in the Before phase
         bMode := DR Get draw mode (Area)
            `Set bMode equal to the drawing mode   
      :(During)
            `If we are in the During phase
         DR SET DRAW MODE (Area;bMode)
            `Set the drawing mode
   End case

DR Get draw mode.
