Report a bug with a simple example program, please.
AFAIK, there already is a bug report on that in the bug tracker (I once
read it but some days ago I failed to find it, though). Moreover it
would be good to do a test with qt as well, before filing another report.
Why do you think QueueAsyncCall isn't done?
In the thread "Event handling example project: results for gtk2 and
fpGUI" I already stated that it suffers from the same problem as
TThread.Synchronize.
So in fact it might be a good idea to file another bug report.
I think it would be best to put the "Event handling example project" in
the "examples" directory in the svn, so it can easily be used for
testing and I can mention same in the bug report.
As far as I can see, it just needs to wake up the main thread when a
message is queued (something I do manually for now).
Hmm. If you do the same that synchronize does (i. e. call
"WakeUpMainThread" ) I don't think it will work (with gkt).
This bug is reported in http://bugs.freepascal.org/view.php?id=13120.
Supposedly this in fact is the bug report I had been reading (and failed
to find as I searched for "synchronize). As (with gtk) the same issue
can be seen with Synchronize, I'll just add a comment to this report.
No one that knows lcl message loop internals have really commented on
how this must be solved.
But AFAIK, in the latest _binary_release_ of the LCL synchronize did
work on gtk, so someone _has_ been working on that and did not notice
that he broke it. :(
