Re: libglade warning - unknown widget class GtkComboBox

Hmmm...what is the proper way to initialize libglade?  After switching some 
of my functions around I found that when one window in particular is 
initialized (using glade_xml_new and autoconnect) libglade magically 
recognizes the GtkComboBox class.  I put that initialization first in my 
program and everything works fine now but that is totally a kludge.  I do 
exactly the same thing in initializing all the other windows:

xml = glade_xml_new("filename", NULL, NULL);
if (xml == NULL)
  //error

glade_xml_signal_autoconnect( xml);
//retrieve the window widget

.
. // repeat for several windows
.

gtk_main();

Subject: libglade warning - unknown widget class GtkComboBox


I've run into some difficulty with libglade and I'm not sure how to fix it. 
I had an old glade file (mainwin.glade) that I was using to generate gtk+1.2 
code.  I used the libglade-convert function to bring it up to the glade 
2.6.0 level. Then I edited the file some, removing option menus and other 
deprecated widgets, replacing them with combo boxes and such.  I also added 
other glade 2.6.0 generated files to my baseline for other windows I needed 
to create.  Originally, I used glade to generate the interface.[ch] files 
for mainwin.glade, but since I had to change all my calls to 
gtk_object_get_data to conform with gtk 2.4.X, I decided to chuck the glade 
generated source and use libglade instead.  However, now when I run my 
program I get the following warning for my combo boxes and the widgets don't 
appear in the window:

(dva:5177): libglade-WARNING **: unknown widget class 'GtkComboBox'

The wierd part about this is in the files I generated with glade 2.6.0 I 
don't get a warning like this for the combo boxes and they work just fine. 
I compared the two files for differences and couldn't find any of 
consequence...but I haven't inspected glade SGML before so I'm probably 
missing something.

Any ideas?

I build with

pkg-config --cflags gtk+-2.0 libglade-2.0
pkg-config --libs gtk+-2.0 libglade-2.0
