You need
to have the child widgets as member objects. If you create them as
local variables of the on_expose_event function, they will be destroyed
when they go out of scope.

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

My child widgets are private members of my class, so the are not out of
scope
