DESCRIPTION:
|
||
|
|
This file will implement an API: FixFontsOnLanguageChange().
|
||
|
|
The USER32 or Regional Settings code should own this API. The fact that it's
|
||
|
|
in the shell is a hack and it should be moved to USER32. This font will
|
||
|
|
be called when the MUI language changes so the fonts in the system metrics
|
||
|
|
can be changed to valid values for the language.
|
||
|
|
|
||
|
|
This API should be called in three cases:
|
||
|
|
a. When the user changes the language via the Regional Settings CPL UI.
|
||
|
|
b. During a user login, USER32 should see if the language changed and
|
||
|
|
call this API. This will handle the case where admins change the
|
||
|
|
language via login screens and reboot. This is not currently implemented.
|
||
|
|
c. The language is changed via some other method (admin login scripts most likely)
|
||
|
|
and the user opens the display CPL. This method is a hack, especially
|
||
|
|
since (b) isn't implemented.

Sankar ?/??/???? - Created for Win2k or before in desk.cpl.
|
||
|
|
BryanSt 3/24/2000 - Make to be modular so it can be moved back into USER32.
|
||
|
|
Made the code more robust. Removed creating custom appearance
|
||
|
|
schemes in order to be compatible with new .theme and
|
||
|
|
.msstyles support.
