Hey everyone, I am trying to write a MATLAB GUI where I want to display a live output of the webcam on the interface alongside with a DAQ interface with a listener that sends current to coils. I followed several similar topics and now I have something that works fine. There remains a small problem though: I am unable to close the GUI window manually. The only thing that works is
command. If I attempt to close GUI window normally, the command window outputs the warning:
Warning: Error occurred while executing the listener callback for event Custom defined for class asyncio.Channel:
Error using matlab.webcam.internal.PreviewController/closePreview
Invalid or deleted object.
> In asyncio.Channel/onCustomEvent (line 429)
In asyncio.Channel>@(source,data)obj.onCustomEvent(data.Type,data.Data) (line 361)
And the warning repeats each time I attempt to close. It appears that something is deleted before it should have been deleted but I don't understand what is happening. As a side note, the interface does not output such a warning if I remove the code related to live webcam preview.
