    create
    	default_create
    			-- Process instances of classes with no creation clause.
    			-- (Default: do nothing.)
    			-- (from ANY)

    feature -- Access

    	generating_type: STRING_8
    			-- Name of current object's generating type
    			-- (type of which it is a direct instance)
    			-- (from ANY)

    	generator: STRING_8
    			-- Name of current object's generating class
    			-- (base class of the type of which it is a direct instance)
    			-- (from ANY)

    	lvs_ex_checkboxes: INTEGER_32 is 4
    			-- Version 4.70.
    			-- Enables check boxes for items in a list view
    			-- control. Effectively, when set to this style, the control
    			-- will create and set a state image list using
    			-- DrawFrameControl. Check boxes are visible and functional
    			-- with all list view modes. You can obtain the state of the
    			-- check box for a given item with ListView_GetCheckState. To
    			-- set the check state, use ListView_SetCheckState.

    	lvs_ex_flatsb: INTEGER_32 is 256
    			-- Version 4.71.
    			-- Enables flat scroll bars in the list view.
    			-- If you need more control over the appearance of the list
    			-- view's scroll bars, you should manipulate the list view's
    			-- scroll bars directly using the Flat Scroll Bar APIs. If
    			-- the system metrics change, you are responsible for adjusting
    			-- the scrollbar metrics with FlatSB_SetScrollProp. See Flat
    			-- Scroll Bars for further details.

    	lvs_ex_fullrowselect: INTEGER_32 is 32
    			-- Version 4.70.
    			-- When an item is selected, the item and all its subitems are
    			-- highlighted. This style is available only in conjunction
    			-- with the LVS_REPORT style.

    	lvs_ex_gridlines: INTEGER_32 is 1
    			-- Version 4.70. Displays gridlines around items and subitems.
    			-- This style is available only in conjunction with the LVS_REPORT
    			-- style.

    	lvs_ex_headerdragdrop: INTEGER_32 is 16
    			-- Version 4.70. Enables drag-and-drop reordering of columns in
    			-- a list view control. This style is only available to list
    			-- view controls that use the LVS_REPORT style.

    	lvs_ex_infotip: INTEGER_32 is 1024
    			-- Version 4.71. When a list view control uses the
    			-- LVS_EX_INFOTIP style, the LVN_GETINFOTIP notification message
    			-- is sent to the parent window before displaying an item's
    			-- tooltip.

    	lvs_ex_labeltip: INTEGER_32 is 16384
    			-- Version 5.80. If a partially hidden label in any list view
    			-- mode lacks tooltip text, the list view control will unfold
    			-- the label. If this style is not set, the list view control
    			-- will unfold partly hidden labels only for the large icon mode.

    	lvs_ex_multiworkareas: INTEGER_32 is 8192
    			-- Version 4.71. If the list view control has the LVS_AUTOARRANGE
    			-- style, the control will not autoarrange its icons until one or
    			-- more work areas are defined (see LVM_SETWORKAREAS). To be
    			-- effective, this style must be set before any work areas are
    			-- defined and any items have been added to the control.

    	lvs_ex_oneclickactivate: INTEGER_32 is 64
    			-- Version 4.70. The list view control sends an LVN_ITEMACTIVATE
    			-- notification message to the parent window when the user clicks
    			-- an item. This style also enables hot tracking in the list view
    			-- control. Hot tracking means that when the cursor moves over an
    			-- item, it is highlighted but not selected. See the Remarks for a
    			-- discussion of item activation.

    	lvs_ex_regional: INTEGER_32 is 512
    			-- Version 4.71. The list view will create a region that includes
    			-- only the item icons and text and set its window region to that
    			-- using SetWindowRgn. This will exclude any area that is not part
    			-- of an item from the window region. This style is only available
    			-- to list view controls that use the LVS_ICON style.

    	lvs_ex_subitemimages: INTEGER_32 is 2
    			-- Version 4.70. Allows images to be displayed for subitems.
    			-- This style is available only in conjunction with the LVS_REPORT
    			-- style.

    	lvs_ex_trackselect: INTEGER_32 is 8
    			-- Version 4.70. Enables hot-track selection in a list view
    			-- control. Hot track selection means that an item is
    			-- automatically selected when the cursor remains over the item
    			-- for a certain period of time. The delay can be changed from
    			-- the default system setting with a LVM_SETHOVERTIME message.
    			-- This style applies to all styles of list view control. You
    			-- can check whether or not hot-track selection is enabled by
    			-- calling SystemParametersInfo.

    	lvs_ex_twoclickactivate: INTEGER_32 is 128
    			-- Version 4.70. The list view control sends an LVN_ITEMACTIVATE
    			-- notification message to the parent window when the user
    			-- double-clicks an item. This style also enables hot tracking
    			-- in the list view control. Hot tracking means that when the
    			-- cursor moves over an item, it is highlighted but not
    			-- selected. See the Remarks for a discussion of item
    			-- activation.

    	lvs_ex_underlinecold: INTEGER_32 is 4096
    			-- Version 4.71. Causes non-hot items that are activatable to be
    			-- displayed with underlined text. This style requires that
    			-- LVS_EX_TWOCLICKACTIVATE also be set. See the Remarks for a
    			-- discussion of item activation.

    	lvs_ex_underlinehot: INTEGER_32 is 2048
    			-- Version 4.71. Causes hot items that are activatable to be
    			-- displayed with underlined text. This style requires that
    			-- LVS_EX_ONECLICKACTIVATE or LVS_EX_TWOCLICKACTIVATE also be
    			-- set. See the Remarks for a discussion of item activation.
