Can someone give me an example of how to use the PtGroup widget without
PhAB?
Mostly, I’d like to know how to “add” widgets to a group. Thanks.

Honestly, I’ve never done this exactly, however I think you
would first do an ApCreateWidget() for the PtGroup, then do
a PtSetParentWidget() on the PtGroup() and then use
ApCreateWidget() on the widget you want created in
the group.

Close. Use PtCreateWidget() to create a PtGroup. Because it’s a container,
it becomes the default parent; any widgets that you create afterward become
children of the group if you pass Pt_DEFAULT_PARENT as the parent argument
to PtCreateWidget().
(The Ap* functions are for PhAB applications only.)

… or instead of relying on Pt_DEFAULT_PARENT, just pass the PtGroup’s
widget pointer. This will not only make your code more explicit and
easier to understand – it will also make it safer: if one of the
children of the PtGroup happens to be a container, it will become the
default parent, and Pt_DEFAULT_PARENT will put the next child in the
wrong place…
