>   Add arrangement stuff to GroupWidgets.

I have a VERY odd bug here.

I REALLY don't know where it comes from and why it happens.
Someone please try it out and tell me.

Just run the simple-button example and look at the source:
The buttons are added in order 1,2,3,4.

Usually, thy should be ordered like this:

[              button 1              ]
[ button 2 ] [ button 3 ] [ button 4 ]

But instead, the two lines are revererted:

[ button 2 ] [ button 3 ] [ button 4 ]
[              button 1              ]

This is because of the list that contains the subwidgets for each
group-widget.
It adds new items with push_back(), which correctly works for the
lower part.
However, if I change that to push_front(), I get:

[              button 1              ]
[ button 4 ] [ button 3 ] [ button 2 ]

so, it's completely revereted, as expected.

What I wonder is:
class Subwidgets is used by both, ContainerWidget AND GroupWidget.
The SAME class!
So why does it order the widgets in the correct order for
ContainerWidgets (the thing that contains the three buttons in
horizontal order) and in the reverted order for GroupWidgets?

I can't find the bug here.

Help is appreciated.

Thanks in advance

Alex
