 Hi,

 I am trying to use threads in my activity.  However, the UI locks up

 the thread is already initialized and running, waiting on a Queue for a
 work request. After I make a request, this is when the UI locks up
 (although the request completes)

 I have tried both gtk.gdk.threads_init() and gobject.threads_init() in
 my activity initialization before I call super

I think you need to do it earlier, in the module scope.

HTH,

Here is some code which runs multiple threads successfully on an xo.  Look
for ServerThread:

 Hope not being very inane...

Hi Shikar,

You might want to look at how James Simmons uses threads in his ReadEtexts
Activity to do speech synthesis using a thread too..

http://dev.laptop.org/git?p=activities/readetexts;a=blob;f=ReadEtextsActivity.py;h=c8c7086a4dd9448a2f81b96150dcb551c6d5d217;hb=HEAD

Around line 56 or so...

Hope it helps :)

Best,
Hemant

Where's the code?

The Distance activity uses threads, gtk, and dbus without any problem, so
that may be a good reference code.
