Drawing Modes

Two drawing modes have been superseded in G2 5.0:

For information about drawing modes, see the G2 Superseded Practices document, available from Gensym on request.

Unscheduled Drawing

The Allow-scheduled-drawing? attribute in the Drawing Parameters system table determines whether drawing is performed immediately (attribute is no) or by a scheduled task (attribute is yes).

In G2 5.0, immediate drawing is a superseded practice. In place of immediate drawing, always use scheduled drawing by specifying Allow-scheduled-drawing? as yes.

XOR Drawing Mode

The Paint-mode? attribute in the Drawing Parameters system table specifies whether drawing is done in XOR mode (attribute is no) or Paint mode (attribute is yes).

In G2 5.0, XOR mode is a superseded practice. In place of XOR mode, always use Paint mode by specifying Paint-mode? as yes. Paint mode is the default mode when you start G2.
