You can poll shared object for stop flag in worker thread (in something like timer object). And besides that, you have no other options in Python. Damn, I was hoping to be able to use interruption instead of polling.

[pygtk] shutting down worker threads
Hi guys, I have been wrapping my brain around the idea of getting asynchronous gui updates with worker threads working, and I have covered all but the last step. When I want to stop my program, how do I interrupt what the worker threads are doing to tell them it is time to stop? I have attached a simple example which demonstrates what I am working on. Try hitting the thread button a bunch of times and them closing the window.

Thanks, Jason Pepas Here are some code snipits we use for shutting down threads. class CommonWorker(threading.Thread): Common threading class def __init__( self ): Initialize threading.Thread.__init__(self) # for keeping status self.count = 0 # we aren't done yet self.done = False # cancelled will be set when the thread should stop self.cancelled = False # quit even if thread is still running self.setDaemon(1) def please_die( self ): Tell the thread to die and is safe to call from other threads self.cancelled = True class UpgradableListReader(CommonWorker): Read available upgrades and store them in a tuple def __init__( self, installed, upgrade_only, view_prefs ): Initialize CommonReader.__init__(self) # [snip] def run( self ): fill upgrade tree #[snip] # in appropriate places such as loops add this line if self.cancelled: self.done = True; return from the main thread: self.up_thread = UpgradableListReader(installed_list, upgrade_only_flag, preferences) ... self.up_thread.please_die() -- Brian [EMAIL PROTECTED] ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
