scan watcher#

../../../_images/datawatcher.png

This widget observes a folder and its subfolders for a given path, waiting for acquisitions to finish. The widget will wait indefinitely until an acquisition is completed. Once an acquisition is finished, a signal containing the folder path is emitted.

  • ‘Select folder’: Opens a dialog to select the top-level directory to observe.

  • ‘Start observation’: Starts the observation.

  • ‘Stop observation’: Stops the observation.

Environment variable#

The widget will automatically set the value of DATADIR if such an environment variable exists.

Note

Internally, the observation is run from a thread managed by ftseries.
