Re: newbie directions?

[Yiannis Gatsoulis <menig leeds ac uk>]

thank you all for your help and your advices. i was still going a bit 
mad as i had a gtkcomboboxentry and
gtk_combo_set_popdown_strings(GTK_COMBO(tableCombo),  tableNames);
was failing  with the errors:
invalid cast from gtkcomboboxentry  to gtkcombo
gtk_combo_set_popdown....: assertion GTK_IS_COMBO (combo) failed

i thought that class gtkcomboboxentry is a subclass of gtkcombobox which 
in turn is a subclass of gtkcombo and as a result it would inherit all 
its properties and methods. isnt that the case? i also tried it with 
gtkcombobox with no luck. anyway, it worked fine only when i changed 
widgets to gtkcombo in the xml file.

thanks again.
