The function
set-application-themed
controls whether a LispWorks application should be themed.
On Windows XP, LispWorks is "themed", that is it uses the current theme of the desktop. You can switch this off by calling
(win32:set-application-themed nil)
On non-XP systems, or when the application does not have Common Controls 6, this call has no effect.
set-application-themed
affects only windows that are created after it was called. Normally, it should be called before any window is created, so all LispWorks windows will appear with the same theme. However,
set-application-themed
can be called multiple times in the same run.
