+
+ * e-dialog-widgets.c (get_radio_value): Implemented. Amazing that
+ one has to go through so much pain to get a stupid value from
+ GTK+.
+ (hook_option_menu): Implemented. Same complaint.
+ (get_toggle_value): Implemented.
+ (get_spin_button_value): Implemented.
+ (get_entry_value): Implemented.
+ (e_dialog_widget_hook_value): Function to hook a widget to the
+ variable it will modify.
+ (e_dialog_get_values): Function to feed the variables from a
+ dialog's widgets.
+ (e_dialog_xml_widget_hook_value): Function to hook a widget from
+ a Glade file.
+

* e-util.c, e-util.h: Added e_write_file.
