id& |
Reserved for future implementation. Must be 0 for a graphic window or bitmap. |
|
REDRAW |
Optional parameter that causes all drawing statements to be buffered until a GRAPHIC REDRAW statement is executed, or the operating system chooses to update the target window. Without REDRAW, all graphical statements (Line, Box, etc.) are performed immediately. However, in certain intensive drawing operations, it may be preferable to delay the display until a number of statements have been performed. In some cases, this can improve the overall performance dramatically. |
