I just tested again here, and using postmessage with gtk2 from an
external thread (from a library) works perfectly.
As taken from some example code, I just created a user thread with
TMyThread.create(). It does run and does
while not Terminated do begin
sleep(2000);
PostMessage(Handle, LM_MY_MESSAGE, 2, 0);
end;
in TFom1 I have:
procedure MyThreadMessage(var MyMessage: TMyMessage);
message(LM_MY_MESSAGE);
and
procedure TForm1.MyThreadMessage(var MyMessage: TMyMessage);
begin
Memo1.Lines.Add('MyMessage' + InttoStr(MyI));
end;
MyThreadMessage is never called, even though the hread is verified to
call PostMessage.
What am I doing wrong ?
Have you built your project with -dusecthreads?
Not really. As I did not find where to set this, I deleted the
appropriate $ifdef in the project source code. Could this be a problem ?
(How to define the -dusecthreads in the Lazarus IDE ?)
Thanks for your answers,
-Michael
