    -- A toolbar can have a combination of the following styles.

    	tbstyle_altdrag: INTEGER_32 is 1024
    			-- Allows the user to change the position of a toolbar
    			-- button by dragging it while holding down the ALT key.
    			-- If this style is not specified, the user must hold
    			-- down the SHIFT key while dragging a button. Note
    			-- that the Ccs_adjustable style must be specified to
    			-- enable toolbar buttons to be dragged.

    	tbstyle_autosize: INTEGER_32 is 16
    			-- The toolbar will not assign the standard width to
    			-- the button. Instead, the buttons width will be calculated
    			-- based on the width of the text plus the image of the
    			-- button.

    	tbstyle_button: INTEGER_32 is 0
    			-- Creates a standard push button.

    	tbstyle_check: INTEGER_32 is 2
    			-- Creates a button that toggles between the pressed
    			-- and not pressed states each time the user clicks it.
    			-- The button has a different background color when it
    			-- is in the pressed state.

    	tbstyle_checkgroup: INTEGER_32 is 6
    			-- Creates a check button that stays pressed until
    			-- another button in the group is pressed.

    	tbstyle_customerase: INTEGER_32 is 8192
    			-- Generates NM_CUSTOMDRAW notification messages when
    			-- it processes WM_ERASEBKGND.

    	tbstyle_dropdown: INTEGER_32 is 8
    			-- Creates a drop-down list button. If the toolbar has
    			-- the TBSTYLE_EX_DRAWDDARROWS extended style, an arrow
    			-- will be displayed next to the button.

    	tbstyle_flat: INTEGER_32 is 2048
    			-- Creates a transparent toolbar with flat buttons.
    			-- The apparence of the button change when the user
    			-- move the mouse on the button.

    	tbstyle_group: INTEGER_32 is 4
    			-- Creates a button that stays pressed until another
    			-- button in the group is pressed.

    	tbstyle_list: INTEGER_32 is 4096
    			-- Places button text to the right of button bitmaps.
    			-- To avoid repainting problems, this style should be
    			-- set before the toolbar control becomes visible.

    	tbstyle_sep: INTEGER_32 is 1
    			-- Creates a separator, providing a small gap between
    			-- button groups. A button that has this style does not
    			-- receive user input.

    	tbstyle_tooltips: INTEGER_32 is 256
    			-- Creates a tooltip control that an application can
    			-- use to display descriptive text for the buttons in
    			-- the toolbar.

    	tbstyle_transparent: INTEGER_32 is 32768
    			-- Version 4.71. Creates a transparent toolbar. In a transparent toolbar,
    			-- the toolbar is transparent but the buttons are not. Button text appears
    			-- under button bitmaps. To prevent repainting problems, this style should
    			-- be set before the toolbar control becomes visible.
    			-- A button in a toolbar can have a combination of the following styles.

    	tbstyle_wrapable: INTEGER_32 is 512
    			-- Creates a toolbar that can have multiple lines of
    			-- buttons. Toolbar buttons can "wrap" to the next
    			-- line when the toolbar becomes too narrow to include
    			-- all buttons on the same line. Wrapping occurs on
    			-- separation and non-group boundaries.

    feature -- Platform

    	operating_environment: OPERATING_ENVIRONMENT
    			-- Objects available from the operating system
    			-- (from ANY)

    feature -- Tool bar button styles

    	btns_autosize: INTEGER_32 is 16
    			-- Version 5.80. Specifies that the toolbar control should
    			-- not assign the standard width to the button. Instead,
    			-- the button's width will be calculated based on the width
    			-- of the text plus the image of the button.
    			-- Use the equivalent style flag, TBSTYLE_AUTOSIZE, for
    			-- version 4.72 and earlier.

    	btns_dropdown: INTEGER_32 is 8
    			-- Version 5.80. Creates a drop-down style button that
    			-- can display a list when the button is clicked. Instead
    			-- of the WM_COMMAND message used for normal buttons,
    			-- drop-down buttons send a TBN_DROPDOWN notification.
    			-- An application can then have the notification handler
    			-- display a list of options. Use the equivalent style
    			-- flag, TBSTYLE_DROPDOWN, for version 4.72 and earlier.
    			-- If the toolbar has the TBSTYLE_EX_DRAWDDARROWS extended
    			-- style, drop-down buttons will have a drop-down arrow
    			-- displayed in a separate section to their right. If the
    			-- arrow is clicked, a TBN_DROPDOWN notification will be
    			-- sent. If the associated button is clicked, a WM_COMMAND
    			-- message will be sent.

    	btns_showtext: INTEGER_32 is 64
    			-- Version 5.81. Specifies that button text should be
    			-- displayed. All buttons can have text, but only those
    			-- buttons with the BTNS_SHOWTEXT button style will
    			-- display it. This button style must be used with the
    			-- TBSTYLE_LIST style and the TBSTYLE_EX_MIXEDBUTTONS
    			-- extended style. If you set text for buttons that do
    			-- not have the BTNS_SHOWTEXT style, the toolbar control
    			-- will automatically display it as a ToolTip when the
    			-- cursor hovers over the button. This feature allows your
    			-- application to avoid handling the TBN_GETINFOTIP
    			-- notification for the toolbar.

    feature -- Tool bar extended styles

    	tbstyle_ex_doublebuffer: INTEGER_32 is 128
    			--  Version 6. This style requires the toolbar to be double
    			-- buffered. Double buffering is a mechanism that detects when
    			-- the toolbar has changed.
    			-- Note  Comctl32.dll version 6 is not redistributable but it
    			-- is included in Microsoft Windows XP or later. To use
    			-- Comctl32.dll version 6, specify it in a manifest. For more
    			-- information on manifests, see Using Windows XP Visual Styles.

    	tbstyle_ex_drawddarrows: INTEGER_32 is 1
    			-- Version 4.71. This style allows buttons to have a separate
    			-- dropdown arrow. Buttons that have the BTNS_DROPDOWN style
    			-- will be drawn with a drop-down arrow in a separate section,
    			-- to the right of the button. If the arrow is clicked, only
    			-- the arrow portion of the button will depress, and the toolbar
    			-- control will send a TBN_DROPDOWN notification to prompt the
    			-- application to display the dropdown menu. If the main part
    			-- of the button is clicked, the toolbar control sends a
    			-- WM_COMMAND message with the button's ID. The application
    			-- normally responds by launching the first command on the menu.
    			-- There are many situations where you may want to have only
    			-- some of the dropdown buttons on a toolbar with separated.
    			-- To do so, set the TBSTYLE_EX_DRAWDDARROWS extended style.
    			-- Give those buttons that will not have separated arrows the
    			-- BTNS_WHOLEDROPDOWN style. Buttons with this style will have
    			-- an arrow displayed next to the image. However, the arrow will
    			-- not be separate and when any part of the button is clicked,
    			-- the toolbar control will send a TBN_DROPDOWN notification.
    			-- To prevent repainting problems, this style should be set
    			-- before the toolbar control becomes visible.

    	tbstyle_ex_hideclippedbuttons: INTEGER_32 is 16
    			-- Version 5.81. This style hides partially clipped buttons.
    			-- The most common use of this style is for toolbars that are
    			-- part of a rebar control. If an adjacent band covers part of
    			-- a button, the button will not be displayed. However, if the
    			-- rebar band has the RBBS_USECHEVRON style, the button will be
    			-- displayed on the chevron's dropdown menu.

    	tbstyle_ex_mixedbuttons: INTEGER_32 is 8
    			-- Version 5.81. This style allows you to set text for all
    			-- buttons, but only display it for those buttons with the
    			-- BTNS_SHOWTEXT button style. The TBSTYLE_LIST style must also
    			-- be set. Normally, when a button does not display text, your
    			-- application must handle TBN_GETINFOTIP to display a ToolTip.
    			-- With the TBSTYLE_EX_MIXEDBUTTONS extended style, text that
    			-- is set but not displayed on a button will automatically be
    			-- used as the button's ToolTip text. Your application only
    			-- needs to handle TBN_GETINFOTIP if it needs more flexibility
    			-- in specifying the ToolTip text.
