This command is not thread-safe, it cannot be used in preemptive code.
Description
The REDRAW WINDOW command provokes a graphical update of the window whose reference number you pass in window.
If you omit the window parameter, REDRAW WINDOW applies to the frontmost window for the current process.
Note: 4D handles the graphical updates of the windows each time you move a window, resize it, or bring it to the front, as well as when you change the form and/or the values displayed in the window. You will rarely use this command.
