[napari 0.5.4, pyqt6] Cannot create annotator

[psobolewskiPhD]

If I open an image in napari 0.5.4 and then launch the widget (from Plugins menu) and click Create, I get a traceback:

It's referring to napari_bbox.boundingbox.napari_0_4_18 so I suspect it's somehow not properly detecting napari 0.5.4?

Wow, that's an interesting one...

It's referring to napari_bbox.boundingbox.napari_0_4_18 so I suspect it's somehow not properly detecting napari 0.5.4?

When there's a bigger change in the inner logic of napari, I have to adapt my code to accomodate these into the bounding box layer. The last such was with 0.5.0, so here it imports from napari_bbox.boundingbox.napari_0_5_0.qt_bounding_box_control, but as in this part of the code there were no changes in napari, it will simply import from napari_bbox.boundingbox.napari_0_4_18.qt_bounding_box_control. At a first glance, I think that the plugin is not compatible with Qt6, only Qt5, but I'll take a look at it later.

[psobolewskiPhD]

Ah! Works perfectly with a new env with napari 0.5.4 and pyqt5.

[psobolewskiPhD]

With a little help from microsoft copilot, I think I have a fix. Will test locally and then open PR.
