Ordering of panels that are loaded in different threads

[swati505]

I have a multithreaded application. Each thread loads a number of panels into memory.
My startup application panel(say panel C) belongs to a thread (say X).
I'm trying to display a panel A that belongs to thread X from a panel B of thread Y through a callback on a button on panel B.
My problem is that when I do this, the panel A does become visible, but panel C also comes into the foreground and I can never get panel B to be interleaved between the two panels of the same thread.
Is there a way around this?

Thanks,
Swati

Hi Swati,

There's two ways you can do this:

1) You can post a deferred call to a thread using PostDeferredCallToThread and specify a function that does a LoadPanel and Display Panel, as well as obtain the thread ID of the main thread.

2) You can utilize a thread safe queue to pass a flag from one thread to the other. Then have the callback on the main thread, and in that tsq's callback call the loadpanel and display panel. I have attached an example of this here. Personally, I think the first suggestion would be easiest, but if you have other data you need to share between threads, then the TSQ is the way to go. Hope this helps!
