I have added another bit of SDL [Simple Direct-media Layer] code to SDL-proto in the dumping grounds. In addition to TinyTalk, I have added an example using Oops! to contrast a more CLOS-ish style and made the test build/compile process easier. Please ignore the many compiler/loader warnings.

Test 1 -- From a SDL Tutorial [ http://www.libsdl.org ]

Test 2 -- Drag a rectangle around in a window

Test 3 -- A drag test using TinyTalk object system Mouse targeting and event dispatch Bitmapped background Separate render and event threads

Test 4 -- Like Test 3, but using the Oops! object system

In each case, use the same strategy to build and run, but use the test-number you want [Linux]: [1] >> ./compile-test1 ## test2 test3 test4 [2] >> gsi [3] > (load "test1") (run-test) ;; "test2" "test3" "test4" [4] > (exit)

Note the separation: - SDL interface code is in "sdl-interface.scm" - SDL independent OO graphic definitions are in "sdl-tt.scm" and "sdl-oops.scm" - Test code which puts the two together and has run-test and stop-test functions are in files "test2.scm", "test3.scm" and "test4.scm".

Code for both object systems is included.

I have tested only under Linux. Please send fixes/suggestions.
