You don't, you can use the widget functions, gtk_widget_set_usize works for me.

I susepct the function mentioned above will also do it.

I cannot find that, perhaps gtk_entry_prepend_text is what you are after.

Looking in the include file, I find these functions:
guint      gtk_entry_get_type     (void);
GtkWidget* gtk_entry_new          (void);
void       gtk_entry_set_text     (GtkEntry      *entry,
                                   const gchar   *text);
void       gtk_entry_append_text  (GtkEntry      *entry,
                                   const gchar   *text);
void       gtk_entry_prepend_text (GtkEntry      *entry,
                                   const gchar   *text);
void       gtk_entry_set_position (GtkEntry      *entry,
                                   gint           position);
gchar*     gtk_entry_get_text     (GtkEntry      *entry);

I guess one of the above functions would do it.

I suspect what you would do is pick up the key press event and then
change the entry text somehow.

I have the following:
   gtk_signal_connect(GTK_OBJECT(bottext), "key_press_event",
                (GtkSignalFunc)entry_insert,NULL);

and

void entry_insert(GtkWidget *widget, GdkEventKey *key)
{
        char buf[2];
        if (key->keyval != XK_Return)
                return;

This last code fragment checks to see if the key pressed is "enter".

I suspect that the gnome messagebox may be what you are after here.

The tutorial mentions a bit on how to make a widget, see section 20.

I don't understand the word "collegate".


Note that I am still a gtk beginner so some of this might be wrong, or not 
"the right way".  I'm just telling you how I did it.
