Groups are new to the discussion. They actually don't become anything
in the generated header files, they're just a convenience to help you
work with your class model. To create a new group you right click and
select "Create Group."
In this case I've created a Birds group to group together my bird
classes. All this really does is provide a visual box around my
classes. It doesn't restrict how classes can interact or what you can
do to individual classes. It does give you a nice way to move a bunch
of related classes around the model canvas. It also gives you a nice
place to document grouped classes.
If you double click on the group title bar you'll get a dialog box
where you can enter group documentation. You can also change the background
colour of your groups by selecting the Background Colour button.
You can add classes to your group by right clicking inside the group
and creating a new class. You can also drag classes in and out of
WARNING: Due to a frustrating bug in wxWidgets you will find
that when you drag a class into or out of your group you will loose
control of it. You'll have to grab it again to continue moving. I
apologize for the inconvenience. As soon as there's a fix to wxWidgets
I will update the KlassModeler.
