New Revision: 54063
URL: http://svn.reactos.org/svn/reactos?rev=54063&view=rev
Log:
[WIN32K]
- Use 64 byte bitmap for keystate instead of 256 elements array (like Windows)
- Fix GetAsyncKeyState lowest bit meaning. See MSDN
- Call low level keyboard hook before setting async key state for keys which distinguish
between left and right hand. Fixes user32:GetKeyState apitest failure
- Improve IsHotKey and delete GetHotKey function to avoid code duplication
- Support WIN key in hotkeys code instead of keyboard.c
