Inconsistent usage patterns

SDLx::Widget::Menu has method render

SDLx::Widget::Textbox has method show

The render method draws the menu on a supplied parameter. The show method acts more like the event_handler or event_hook methods, but registers a show_handler.

It would probably make more sense to use the same design pattern in all the different widgets.

Should we make a document and describe the design pattern?

Or Maybe even make a SDLx::Widget::Stub that can easily be adopted...
