Make widgets visible in a Scrolled Window

["Sebastian Ley" <sebastian ley mmweg rwth-aachen de>]

Hello,

I have a scrolled window, created with
gtk_scrolled_window_add_with_viewport(GTK_SCROLLED_WINDOW (scroll), targetbox);

The targetbox is a vbox, which will get only another vbox named
questionbox packed in. This questionbox gets now stuffed with
widgets. I do not know at build time how many this will be, sometimes
only one, but possibly many more. To be able to display them all I use
the scrolled window.

Here some examples how this could look like:

Now I have two problems:

1) Whenn moving the focus inside the widgets when there is a
   scrollbar, the focus disappears when widgets currently not on the
   screen get it. I want some mechanisme that the focus is always
   visible.

2) Similar to 1), it is possible, that I have a default widget, that
   should be centered (if possible) in the scrolled window.

Do you have any suggestions how to accomplish that?

Thank you in advance,
Sebastian Ley
