Hi List,
I got failure messages like the one I forwarded. I got these in
response to all the four posts I made on 2005-10-28. They are present
in the archives, but 1) I don't know whether the others received them
and 2) I also don't know what these errors really mean. Please anyone
explain me these two questions!
I've written a mail to the person who runs the list [mkestner at novell
dot com], but he didn't answer me.
The four letters were:
* Re: [Gtk-sharp-list] Problem with adding and removing HBox based
classes form a view port.
http://lists.ximian.com/pipermail/gtk-sharp-list/2005-October/006536.html
* Re: [Gtk-sharp-list] TreeView ButonPressEvent doesn't trigger
http://lists.ximian.com/pipermail/gtk-sharp-list/2005-October/006535.html
* Why TreeViewColumn.OnClicked is protected?
http://lists.ximian.com/pipermail/gtk-sharp-list/2005-October/006538.html
* TreeView expander column issues
http://lists.ximian.com/pipermail/gtk-sharp-list/2005-October/006537.html
Thanks in advance!

I guess you should call this.ContactView_GtkViewport.ShowAll() to
redraw your new child widget.
As a side note, you don't need to explicitly use the "this" keyword in
C#. You should only use it when you have an argument of your method
with the same name which masks the class member, so in this particular
case, "ContactView_GtkViewport.ShowAll()" is just enough ;-)
I like your UI approach by the way. Avoiding pop-ups is always a good
idea I think.
