OK and I didn't expect you to send that private answer on a public

in the modern world you create widget subclasses when you need

kind of form, or multiple forms.

Well, if you want you can use variables of type GtkWidgetOfTypeX * and
type cast on the call of constructor. You have to type cast back to
GtkWidget *
Hi,
There is a technical difference when writing GTK+ code in C; for instance
its quite often that you will access methods on the GtkWidgetClass
(like show()/hide()/set_sensitive() etc), also many other apis take GtkWidget *
argument, namely GtkContainer apis which operate on child widgets.
I'm also using the real types in my declarations, though I'm paying
the price with casts.
And here I mean:
GtkMenuItem *dir_or_not = GTK_MENU_ITEM
(gtk_menu_item_new_with_label (Or not));
gtk_menu_shell_append (GTK_MENU_SHELL (directory_filter_menu),
GTK_WIDGET
I think that this is from times where people
used to build GUIs in the code... When they were writing all the container
embedding and all, in C, building their dialogs.
Those times are still very much here. For instance in the application
that gave GTK+ the G in its name.

Hi,
Whatever type is returned, you'll have to do lots of casts, so whatever
convention is used, there's no avoiding that. And returning GtkWidget*
is just the current convention.
I personally would prefer correct types to be used in the API, just to
show exactly what type to expect at runtime.
