Threading related, but not the same, as you are not using synchronize,
are you?
Vincent
Do you mean like below - which then means, I do use synchronize. I
use synchronize to draw on the main form (running in the main thread).
I don't get any lockups as that bug report says, but then I am
running under Ubuntu that uses Gnome desktop. Again, no such issues
under Windows.
TSortThread is the base class for my three different Sorting threads,
so they all use this function.
procedure TSortThread.VisualSwap(A, B, I, J: Integer);
begin
FA := A;
FB := B;
FI := I;
FJ := J;
Synchronize(@DoVisualSwap);
end;
They never attached a sample application, so I can't try it on my
system to see if I get the same issues as they do, but as I stated, I
don't get lockups, only that the threads run in sequence - one after
the other.
What platform are you running on, Windows?
All gui stuff I run on windows. Non visual test apps, I can run on linux too.
If I really want I could do GUI in linux too, but I don't know too much about gtk
and I rather spent time on improving things on the windows platform.
I thought in your initial mail your were talking about having a console test app
with threads. Synchronize is harder then, because you have to call CheckSynchronize
yourself.
Vincent.
