Happy testing.
Some testing results regarding MainThreadEvents.
Done with Lazarus version 0.9.31 revision 29587, fpGUI revision as of
20110217, and FPC 2.5.1:

(1) The scheduled Events only are handled in the Main Thread when GUI
Events for the Form are handled (e.g. always, when a memo that gets the
test output has the focus, which makes it seem to work correctly)
(2) Forbidden, but eventually works like TThread.Synchronize
(3) Similar to (1), but does not even seem to work if the memo has the
focus
(4) Forbidden; Application Crashes
(5) Forbidden; works for some time, then The application closes without
error message
(6) The scheduled Events only are handled in the Main Thread when the
worker thread is terminated
(7) Very funny: In this test environment, the scheduled Events only are
handled in the Main Thread when e.g a completely unrelated worker thread
is created and then terminated
Hope this helps,
-Michael
