I have a problem getting a thread to update a window.
I have a main theread that opens the windows and handles the events. I
launch a thread that needs to update a progress bar. However, If I even
try to do a GrGetWindowInfo() in teh thread and I get a bunch of errors.
Now what I would normally do is use XSendevent() to let the main event
loop update the window. However, there is no XsendEvent() like in nano-X.
Now there is GrSendEventData(). But what info I can find says it is used
in response to a client data request. It needs a serial number, source
windows, etc.
Now, my question is what is the best route to follow?
Can GrSendEventData() be used with serial = 0, source window = 0? What
would I put in packet size vs. data size? All I want to do is send a
pointer to a data area. This way the event loop could handle the drawing
instead of different threads.
