[PyQt] help with designer plugin for custom widget.

[Josh]

I've got a Qt widget and a PyQt binding. I want to make a Designer 
plugin for it.

I have a Designer plugin as a C++ class. It works fine, I can add it to 
layouts, etc.

Am I correct in assuming that my PyQt binding will not work to load the 
C++ class when added via the C++ designer plugin?

I have been trying to make a PyQt designer plugin by subclassing 
QPyDesignerCustomWidgetPlugin but I cant get designer to load it.

I tried placing the pyqt plugin in directories specified in both 
QT_PLUGIN_PATH & PYQTDESIGNERPATH but it never shows up.

I suspect I'm not putting it in the right place, but I'm not sure. 
designer doesn't indicate any errors.

Anyone have any suggestions on what to check?

Thanks!

Josh
