-- <description>
-- The Gtk_Combo widget consists of a single-line text entry field and a
-- drop-down list. The drop-down list is displayed when the user clicks on a
-- small arrow button to the right of the entry field.
--
-- The drop-down list is a Gtk_List widget and can be accessed using the list
-- member of the Gtk_Combo. List elements can contain arbitrary widgets, but
-- if an element is not a plain label, then you must use the
-- Gtk_List.Set_Item_String function. This sets the string which will be
-- placed in the text entry field when the item is selected.
--
-- By default, the user can step through the items in the list using the
-- arrow (cursor) keys, though this behaviour can be turned off with
-- Set_Use_Arrows.
--
-- Normally the arrow keys are only active when the contents of the text
-- entry field matches one of the items in the list. If the contents of the
-- entry field do not match any of the list items, then pressing the arrow
-- keys does nothing. However, by calling Set_Use_Arrows_Always you can
-- specify that the arrow keys are always active. If the contents of the entry
-- field does not match any of the items in the list, then pressing the up or
-- down arrow key will set the entry field to the last or first item in the
-- list, respectively.

-- Methods --
-------------
procedure Disable_Activate (Combo_Box : access Gtk_Combo_Record);
-- Disable the standard handler for the return key in the entry field. The
-- default behavior is to popdown the combo box list, so that the user can
-- choose from it. However, if you want to add your own callback for the
-- return key, you need to call this subprogram, and connect a handler to
-- the "activate" signal for the entry.
procedure Set_Case_Sensitive
(Combo_Box : access Gtk_Combo_Record;
Val : Boolean := True);
-- Specify whether the text entered into the Gtk_Entry field and the text
-- in the list items are case sensitive. This may be useful, for example,
-- when you have called Set_Value_In_List to limit the values entered, but
-- you are not worried about differences in case.
procedure Set_Item_String
(Combo_Box : access Gtk_Combo_Record;
Item : access Gtk.Item.Gtk_Item_Record'Class;
Item_Value : UTF8_String);
-- Set the string to place in the Gtk_Entry field when a particular list
-- item is selected. This is needed if the list item is not a simple label.
procedure Set_Popdown_Strings
(Combo_Box : access Gtk_Combo_Record;
Strings : Gtk.Enums.String_List.Glist);
-- Set all the items in the popup list.
procedure Set_Use_Arrows
(Combo_Box : access Gtk_Combo_Record;
Val : Boolean := True);
-- Specify if the arrow (cursor) keys can be used to step through the
-- items in the list. This is on by default.
procedure Set_Use_Arrows_Always
(Combo_Box : access Gtk_Combo_Record;
Val : Boolean := True);
-- Specify if the arrow keys will still work even if the current contents
-- of the Gtk_Entry field do not match any of the list items.
procedure Set_Value_In_List
(Combo_Box : access Gtk_Combo_Record;
Val : Boolean := True;
Ok_If_Empty : Boolean := False);
-- Specify whether the value entered in the text entry field must match
-- one of the values in the list. If this is set then the user will not be
-- able to perform any other action until a valid value has been entered.
-- If an empty field is acceptable, the Ok_If_Empty parameter should be
-- True. If the value entered must match one of the values in the list, val
-- should be True.
