time out in event structure.

[labmaster]

Recently, I study the design pattern.

I used all events in one event structure.

Usually, "Go button value change event" and "Time-out" need to acquire some data for a long time via RS-232.

To have responsible UI event, therefore, I would like to put "Time-out" outside event structure using another while loop in parallel loop scheme.

My question is how to deactivate "Time-out" when some UI event is fired and activate Time-out in case of completing UI event without any confliction of RS-232 communication.

In addtion, some variable such as VISA port should be updated in outside event structure.

You are on the right track. Move the operations that will take a long time to a second parallel loop and pass the data back to the GUI event loop using a queue, functional global, or even a user event. In terms of how to implement this functionality look at the producer/consumer and master/slave design pattern templates.
