Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

WM_SYSCOLORCHANGE
 
The WM_SYSCOLORCHANGE message is sent to all child windows of the desktop
when a change is made to the system colors by the WinSetSysColors function.
When the WM_SYSCOLORCHANGE message is received, applications that depend on
the system colors can query the new color values using the
WinQuerySysColors function.
 
After the WM_SYSCOLORCHANGE messages are sent, all windows in the system are
invalidated so that they will be redrawn with the new system colors.
 
The default window procedure takes no action on this message.
