Purpose |
Update buffered graphical statements, drawing them to the selected graphic target. |
|
Syntax |
GRAPHIC REDRAW |
|
Remarks |
This statement is only needed when GRAPHIC ATTACH with the REDRAW option have been chosen for faster, buffered draw operations. Otherwise, it performs no operation. All PowerBASIC graphical displays are persistent -- they are automatically redrawn for you after resuming from being minimized or temporarily covered by other windows. |
