ShowModal() for a modal form will call it.
Ah really?
It happens in my application!
Then that is your problem.
:-)))
But is it correct behavior ? IMO it is against thread safety, which
should Synchronize guarantee!
The two issues are completely unrelated. The current behaviour is
correct.
I did test in Delphi and Delphi seems also perform synchronize upon
ShowModal
Nowhere is it stated or guaranteed that synchronisation cannot happen
in a GUI event
handler.
But cann't happen if nobody calls ProcessMessages or CheckSynchronize
explicitly.
So if user code is executed in event handler then this execution cann't
be interrupted by thread waiting for "synchronization"
Any code at any time can call the GUI message loop. A modal form is
just one instance.
ModalForm is IMO one example but may be alone in LCL ... as there are no
more controls which do same, does not ?
So in my mind it is very specific case, which should be documented.
Of course there can be any user defined control which will do same ...
Your code must be able to deal with this.
Yes, thanks
