Can I adapt widgets from other megawidget packages?

Yes. However, you need to be very careful about making sure the bindtags are done properly. There’s no way for Snit to take into account all the possible weird things other megawidget frameworks might do wrong. For example, some widgets in BWidgets place their own binding not on a separate bind-tag, but on the widget itself. When used as the hull of a snit::widgetadaptor this causes them to be called before Snit, removing the widget command. A previous version of Snit was tripped by this and threw errors because it tried to operate on and with an already deleted widget command. Snit is now able to deal with this, despite the fact that the ultimate cause is at least bad behaviour of Bwidget, possibly even a bug. This however does not preclude that there might be other issues lurking.
