Is the best general way to check IPC messages in SimpleIPC to spawn a
thread? and check
I noticed in fpgui sample apps that use simpleipc, graemeg checks the
messages in the fpgui OnIdle event, AFAICT, not a separate thread. But
what if you are running a console mode program that has no onidle event?
Obviously "avoid threads where possible" but only if there is a simpler
mechanism not reinventing a thread. So it seems to me onidle in fpgui is
a simpler way than creating a new separate thread yourself, but how to
do it in a program that has no fpgui onidle?
Check manually. What else is left ?
There is no message queue, so no loop in which to check at regular basis.
On that note what would a lazarus app generally do to check for
messages, without locking the app up? A similar OnIdle solution?
Yes. The sample programs check in Application.OnIdle.
Michael.
