use "procedure .... message". But In Delphi/Windows you don't need to
create a server. Just using "procedure .... message" is enough o receive
a message from another process.
No. AFAIK even in Delphi, "message procedures" for non-components are
pretty much abstract (and probably almost useless). The messaging system
you are talking about only works automagically for components belonging
to the Application component (and is therefore limited to the main thread).
If you create a thread in Delphi (even a Tthread descendant) you will
not be able to insert components to it, because it is not a component
itself. So, if you are going to make this messaging work to some degree
in non-main thread on windows, you'll probably need to take care of some
things manually. First, you'll need some window handle created within
your thread, as otherwise OS will not even create a message queue for
this thread. Delphi won't do this for you, AFAIK. Then, in the body of
your thread, you'll need to regularily fetch new messages (GetMessage or
PeekMessage etc) and actually dispatch them to some objects (maybe to
this very tthread object for instance).
If this is possible with FPC/Linux, I
should make sure that it's still possible with the NoGUIApplication package.
When I ported some threaded delphi application to linux I replaced
window handles (used for inter-thread communication) by unix pipes.
These are not exactly the same, but generally provide sufficient
functionality and are quite easy to use. No idea if it is anywhere
appropriate in your case, though.
Hope this helps:)
