class uwsift.queue.TaskQueue(process_pool=None)[source]

Bases: QObject

Global background task queue for loading, rendering, et cetera. Includes state updates and GUI links. Eventually will include thread pools and multiprocess pools. Two threads for interactive tasks (high priority), one thread for background tasks (low priority): 0, 1, 2

add(key, task_iterable, description, interactive=False, and_then=None, use_process_pool=False, use_thread_pool=False)[source]

Add an iterable task which will yield progress information dictionaries.

Expect behavior like this:

for task in queue:
   for status_info in task:
       update_display(status_info)
   pop_display(final_status_info)

Parameters:

key (str) – unique key for task. Queuing the same key will result in the old task being removed and the new one deferred to the end
task_iterable (iter) – callable resulting in an iterable, or an iterable itself to be run on the background
