Usually, you would create the tooltip group together with the widget. 
Something similar is done in the implementation of list views and set views. 
There, not only a widget is created, but also a corresponding model, for 
example. Could you please have a look at the implementation of 
Graphics.UI.Grapefruit.GTK.Backend.Container.listViewBrick to get an idea?

The problem regarding tooltips is that the tooltips signal should probably be 
automatically available for any kind of widget, like IsEnable is. It’s 
currently not supported that such an all-widgets signal depends on some other 
object than the widget object. I’ll try to look at this problem when I find 
the time. If you have a solution for this, please tell me.

Best wishes,
