You may create the combo box using gtk_combo_box_new_with_model.
You insert all the items that may appear in the second combo box in a
GtkListStore. Along with the text, you create a column that contains the
index of
the items in the first combo box that they belong to. Use a

Yes, that's right as the error went away when I explicitly specified the
win32 font.

Great!

The toy font backend is not a real backend. Pango doesn't recognize it
and can't use it. The available ones are FreeType, win32, and ATSUI.
You are using win32 obviously.
Thank you for your excellent reply! I modified the code per your
suggestions and it worked perfectly. Here is the full snippet of code for
anyone else who might find this useful:

I am using gtk_combo_box_new_text() to setup a combo box to display a list of
strings. However, the documentation states that in this case you can only use
the
following set of related (convenience) functions to manipulate the ComboBox:
gtk_combo_box_append_text()
gtk_combo_box_insert_text()

I'm trying to find a way to scale fonts linearly. As far as I can tell, the
way to do it is to use a freetype font and turn hinting off. Using the API,
I tried to pull some code together that would try to do that, but
unfortunately, the font is still scaling non-linearly.

I am using set_cell_data_func with a ComboBox. I noticed that when I call
the append method of the TreeStore, set_cell_data_func is called twice.
The first time, the row has not yet been written into the TreeStore, so the
set_cell_data_func can't perform its function. Is there a reason that GTK
Is there a way to control scrolling in the popup for a ComboBox? I have a
ComboBox with only 10 items. The ComboBox pops up a window with the active
item positioned near the top. If the active item is not one of the first
two items, then scrollbars appear and there is a vast empty space below th
I do check glade_xml_new() and all glade_xml_get_widget() for NULL return.
Problem is that the gtk_main() is already running as I create new windows in
events / callbacks from the existing window. All I would like to do is not
to create and not to show the new window if there are any problems.

Hi all,
the problem is when loading windows from the xml file:
glade_xml = glade_xml_new("ami.glade",NULL,NULL);
I need to know the reference to main window (GtkWindow) to be able to
destroy it, yes?
I can get it like this:
window = glade_xml_get_widget(glade_xml,"window1");
and des
