I do know this. This is why I need to port Martin's NoGUIApplication,
which has an internal message queue, to Lazarus,
I suppose with Linux, FPC (or Lazarus ? ) uses X11 as a message queue
provider.
Nope. On non windows widgetrsets, lazarus implements its own
messagequeue which is handled in application.Idle.
On some widgetsets (iirc Carbon and QT) this messagequeue is mixed with
the messagequeue if that widgetset.
But I was not yet able to find out how to post a message into
the X11 queue (with a thread or another application) and capture this
message by an FPC "procedure ... message" construct. (with FPC/Lazarus
on Windows this does work fine using Windows messages)
AFAIK, X11 has no messagequeue but is based on callbacks.
If it does work with Linux/X1, I need to think how to make it work with
NoGUIApplication, as well. If it does not work in Linux, anyway, I don't
think I'll bother.
