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 = 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 = 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 = 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 = 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 = 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 = 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. invariant -- from ANY reflexive_equality: standard_is_equal (Current) reflexive_conformance: conforms_to (Current) note copyright: "Copyright (c) 1984-2006, Eiffel Software and others" license: "Eiffel Forum License v2 (see http://www.eiffel.com/licensing/forum.txt)" source: "[ Eiffel Software 356 Storke Road, Goleta, CA 93117 USA Telephone 805-685-1006, Fax 805-685-6869 Website http://www.eiffel.com Customer support http://support.eiffel.com ]" end -- class WEL_TB_STYLE_CONSTANTS
