Well, in almost all GUI libraries, you can only do things with the
gui from the main thread. Your best bet would be a producer/consumer
model with a Queue: have the sub thread add commands to a Queue that
the main thread reads out and handles. See for some more discussion
my recent article on www.informit.com (no permalink, I'm afraid,
but if you login and search for my name, you'll find it).
