Custom widget children not shown

[Kees Kling <ckling upcmail nl>]

Hi,

2 weeks ago I wrote a mail about custom widgets, but till now nobody 
reacted on it , so I try again

I want to make a custom widget which has several  standard  widgets as 
child,  like  butoons labels, etc. First I did it on the standard way, 
deribing from a Gtk:;Frame and adding the widgets to the frame and that 
is working pretty well. But I wnat to give the user the abillity to move 
the set of widgets around and I got the Idea to give the widget its own 
Gdk::Window and I tried to change the example in the book (chapter 
26.2). instead of deriving the widget from Gtk::Widget I took a Gtk::Bin 
object and added the childwidgets to this container. In the 
on_expose_event method I create a new Gdk::window and attached it to 
Gtk::bin. It compiles and runs without warnings, but no widgets are 
shown. I only noticed a an eventbox inserted in the custom widget is 
working, because I can connect callbacks to it .

What amI doing wrong or is the way I want to do it not possible.

Please Help
