I don't remember if Designer informs the plugin that it wants the widgets to
be created for use in a preview, so there may not be a way of knowing that.
It may be that one of the PyQt examples can give you some ideas. The analog
clock plugin uses a timer, not a thread, but perhaps it can help you diagnose
what is going wrong.
If you have the source code for the C++ plugin, it may be possible to convert
it to Python. Ask if you need help with that.
