Hi,
Another question... I've noticed that Aqua animations, for example the
pulsing default button, are implemented via a separate thread, which
redraws the button repeatedly. This also causes the view (for example a
custom view that I wrote myself) that contains the button to receive a
drawRect message, of course.
The problem is that this drawRect message is sent from the separate
thread, which means that drawing in all my custom views needs to be
thread-safe. This is a huge pain.
Is there any way around this? Are you all always writing thread-safe
drawRect handlers? It seems like a huge responsibility to make sure this
will always work correctly...
Thanks in advance!
Best regards,
Frederik Slijkerman
