Visualisation issue when switching read mode from 1D to image

[pvalvin]

Dear PymoDAQers

I have prepared a preset for a spectroscopy setup based on a Andor ShamrockCCDComposition.
The 3 1D-modes are working fine (FVB, singletrack, multitrack).
I can switch from 'FVB' to the 'image' mode. It is still working. I can switch back to FVB or singletrack or multitrack. Still working.
But when I switch from 'singletrack' to 'image' or from 'multitrack' to 'image' the viewer disappears and I can't get it back.

The corresponding line in the log fil is :

2024-03-27 13:23:49,288 - py.warnings - WARNING - C:\repo\PyMoDAQ\src\pymodaq\utils\plotting\data_viewers\viewer.py:313: RuntimeWarning: Cannot close dock <Dock Det 00_Viewer_1 (350, 350)> because it is not open.
dock.close()
2024-03-27 13:23:49,290 - pymodaq.pymodaq.daq_viewer.Det 00 - ERROR - pop from empty list

And then we have the Traceback. I can add it if needed.

It seems that the problem refers to a file I should not have to touch.

Thanks for your help,
Cheers,

Pierre

My bad : No bug with an updated version of PyMoDAQ (4.1.13). I was running 4.0.8.
I'm closing the issue.

False joy... Still have the bug. It is difficult to predict when it appears or not.

Hi Sebastien,

I tried again this morning. At my first trial, that was not possible to reproduce a bug.
Then I just changed the organisation of the windows. I wanted to have de spectrum viewer on the bottom instead of having it as a vertical pannel on the right.
And when I switched from spectrum to image mode, the viewer disappeared.
Here is the log again.

It seems the viewer loose the reference of the dock in the process. For the time being, don't move the panels around and I'll come with a patch later
