Created a custom widget in wizard, how to get it in designer

[tescrin]

So ugh. I'm trying to do an example custom widget using the custom widget wizard found in designer/creator.

(I.E. File, new project, other projects, custom widget..)

I did that, hit build, and I can't seem to figure out how to get that custom widget into the designer.
Presumably I'm missing a simple step. I'm crossing my fingers that this is enough information for you to know what step I happen to be missing.

Any help is appreciated, thanks!

EDIT: Maybe I need to include the plugin in whatever project wishes to add the custom plugin to it's form?
