Yep, i will be hyper-interested by that feature...
So, until that day will come, i will use a Java-timer
The question here is: where did you type it?
Inside the loop in thread, after each queue()... and also just before end of
thread.
the next thing to go for, is probably be to try to get this
`CheckSynchronize;` integrated into java in a decent manner
(applicable to most use cases, that is).

*That* does not help. Queue put's the method pointer you provide into a
queue that needs to be read by the *main thread*. It

@ Ewald = thanks.
Hum, i did use checksynchronize but it did not help...
Must it be used with fptimer.ontimer too ?
And why fptimer.ontimer is not executed ?
Will i have more luck with other timer like epiktimer from Graeme (or the
new one from Michael) ?
Thanks.
PS : I will try with some more

When do you call it.

No.

If CheckSynchronize is not executed at regular intervals,
re-@ Ewald :
It *must* be called in the context of the main thread (the thread that
loaded the library)
OOps, so do you mean that CheckSynchronize must be called by Java ?
So i have to add a custom procedure in the fpc library (who will be only a
fpc CheckSynchronize()) ?

Yep, yep, yep some very good news...
1) Added a new procedure in fpc library:
=
procedure uos_checksynchro(PEnv: PJNIEnv; Obj: JObject) ; cdecl;
begin
checksynchronize();
end;
2) And, of course, in fpc library exported as:
=
exports
...
uos_checksynchro name 'Java_uos_checksynchro',
...

@ Ewald, i have try with :
While true do
Begin

CheckSynchronize;
End;
But this does not work...

If the timer event runs in the same thread as your current call to
checksynchro resides then it will work. If it's executed by a different

I use then queue() or synchronize() inside the thread to execute that

When a java class use a fpc library that call jni.CallVoidMethod inside a

If the fpc library call jni.CallVoidMethod directly (not via a thread) =
perfect, it works.
Is that a known problem ?
Not known, but
In general, libraries and threading is not an easy story.
Ok,..., but what is your advice to do a CallVoidMethod inside a thread ?
PS: Everything, inside the thread is working perfectly, only CallVoidMethod
does crash...
Do you think i could have better result with a kind of post-messages ?

That is probably the additional glue code I was talking about in my reply.
