I think it's working!

The plugin UI looks mostly the same as before, and (as far as I cant tell) behaves exactly the same. The only visual differences are:

• the widgets have been grouped into different sections (using QGroupBox)
• the widgets are now centered rather than left-aligned.

plugin using magicgui:

plugin using QtPy directly:

The main internals changes are:

• we're using QtPy directly rather than magicgui
• added a BtrackWidget that inherits from QScrollArea and replaces the magicgui.widgets.Container we were using

I'm having a quick play with it and it looks great. I've noticed an error, when swapping between cell and particle tracking modalities:

        btrack_widget = <btrack.napari.widgets.create_ui.BtrackWidget object at 0x131f97f40>
        config.max_search_radius = 10.0
        btrack_widget.max_search_radius = <PyQt5.QtWidgets.QSpinBox object at 0x12612b520>
     85 # Update widgets from MotionModel values
     86 motion_model = config.motion_model

TypeError: setValue(self, val: int): argument 1 has unexpected type 'float'

I've noticed an error, when swapping between cell and particle tracking modalities:

huh, it's strange that I didn't get that error, but it should be sorted now - I've changed max_search_radius to use a QDoubleSpinBox

[quantumjot]

Looks good to me! I suspect we'll find some other things as we use it more, but I don't want to impede the changeover.

[paddyroddy]

I've had a play and seems to be all working now. As you said @quantumjot, there might be issues, but it is expected as this was a huge piece of work. I will quickly read over the changes once more and merge.

[paddyroddy]

I'm going to merge this now, but just to check. @p-j-smith relax got removed because it should have never been in this list, right?
