Mastering the Wimp (Part 6)
by Lee Calcraft

This program demonstrates the use of the SWI "Wimp_ForceRedraw" to force part of a window's work area to be redrawn. The program updates the time displayed in the window once per second. Whenever the time is changed, the program calls Wimp_ForceRedraw to force the time to be redrawn.

More details on Wimp_ForceRedraw can be found in the RISC OS Programmer's Reference Manual, and on page 47 of this month's magazine (RISC User Volume 3 Issue 4).
