### Using a Thread and a Queue To Accomplish Long Tasks
Queues are a great way for threads to communicate. In this demo program we have a single long-operation that needs to be run. You'll find a function named `long_function_wrapper` where is where you will place your code that takes a long time to execute.
When this function completes running, it sends a message to a Queue which is monitored by the main GUI thread.
The GUI enables you to run more than 1 of these long-running tasks if you want. It keeps track of how many have been requested and tracks when each completes executing.
