Wimp_ForceRedraw

(SWI &400D1)

This SWI has two syntax forms: mark invalid area and extended.

1. The mark invalid area form marks areas of windows as invalid so they can be redrawn later.
2. The extended form allows to update the title bar text without updating the rest of the window.

• Wimp_ForceRedraw (mark invalid area syntax)
• Wimp_ForceRedraw (extended syntax)
