feature -- Basic operations

	extend_no_expand (container: EV_BOX; widget: EV_WIDGET)
			-- Add `widget' to `container' and make `widget' not expandable
		do
			container.extend (widget)
			container.disable_item_expand (widget)
		end

	extend_with_size (container: EV_BOX; widget: EV_WIDGET; a_width, a_height: INTEGER)
			-- Add `widget' to `container' and make `widget' not expandable
			-- Set the minimum size of `widget' to (`a_width',`a_height')
		do
			widget.set_minimum_size (a_width, a_height)
			container.extend (widget)
			container.disable_item_expand (widget)
		end

	extend_button (container: EV_BOX; button: EV_BUTTON)
			-- Add `widget' to `container' and make `widget' not expandable
			-- Set the minimum size of `widget' to the default size for buttons
		do
			Layout_constants.set_default_width_for_button (button)
			container.extend (button)
			container.disable_item_expand (button)
		end

	adjust_sensitivity (a_widget: EV_WIDGET; a_sensitive: BOOLEAN)
			-- Enable/disable sensitivity of given widget according to `a_sensitive'.
		require
			not_a_widget_destroyed: not a_widget.is_destroyed
		do
			if a_sensitive then

feature -- Useful query

	parent_window_from (w: EV_WIDGET): EV_WINDOW
			-- Top parent Window containing `w'.
		require
			w_not_void: w /= Void
		do
			Result ?= w
			if Result = Void and w.parent /= Void then
				Result := parent_window_from (w.parent)
