[Openmcl-devel] “Prehistoric” MCL

[Andrew Shalit]

MCL had a very nice interface to the Macintosh window system. It was all interactive, and didn’t require management of an event loop.  You created window objects and other UI objects. They all had standard methods for standard events. You could override these methods to customize behavior.  I used this early on to create one of the first interactive UI builders for the Mac.

These early versions of MCL did not support threads. I don’t recall when we added thread support, but it was a bunch later.
