Train task run in server.  
Periodically I would like to trigger a status check and update some UI button.

> <https://github.com/Project-MONAI/MONAILabel/blob/main/plugins/slicer/MONAILabel/MONAILabel.py#L184-L186>

Basically I have Train start, status\_check and stop buttons  
When I click start… we switch and enable stop button. After sometime the actual training is finished.

However server provides a method to query the status. How to do it behind the scene… I mean how to simulate the behaviour of auto click for status button for every N seconds.

You can set up a QTimer to run a method periodically. See for example in Endoscopy module:
