Fwd: How do I make a dynamic layout?

[Alessandro Bottoni]

I was reading the messages of the wxwindows list when I read a question that I 
would be happy to see answered by the people of GNUe-Forms project, as well.

How do I make a dynamic layout using GNUe-Forms? Is it possible to change the 
layout and/or the content of a GNUe form at run time? How?

(oh yes: I'm a newbie...:-)

Hi,

I would like to have a window that resizes when its components
are hidden or shown and I am wondering how to approach this.
Suppose I have a vertical layout of windows like this:
        A
        B
        C
        D
        E

Suppose control A is a choice control that allows the
user to choose a mode which controls which subset of windows
B, C, D, and E should appear.

For instance, if A has value 1, then I want the window to
look like this:
        A
        B
        E

whereas if A has value 2, then I want the window to look
like this:
        A
        B
        D

(There are more than two modes, but I think you get the idea.)

If the user changes the mode in A, I want the window to
change.  Using wxWindow::Show (false) on controls B, C, D,
and E of course works fine, but we see big empty gaps.  How
can I close the gap?
