I looked at the InstallFFI4.st and discovered
where I found 'FFI-Kernel-ar.9.mcz',
convertable to .zip files by changing the extension. Then I attempted to
Cuis accepted the Kernal and Tests but failed on the Examples due to
MacIntosh classes which Cuis doesn't support.
Unfortunately that still was insufficient to accept the example at
http://wiki.squeak.org/squeak/2422 but the error is now different:
"Return the HWND currently having the input focus"
<apicall:* return type expected ->*Win32Window 'GetFocus' (void) module:
So any advice?
I'm under the impression Cuis was never intended to use FFI but to do direct
binary input without a C.dll but unfortunately the details of how to do that
for VideoFlow are also beyond my knowledge. Where would I learn that?
