       ttk_vsapi - Define a Microsoft Visual Styles element

       ttk::style  element  create name	vsapi className	partId ?stateMap? ?op-

       The vsapi element factory creates a new element in  the	current	 theme
       whose  visual appearance	is drawn using the Microsoft Visual Styles API
       which is	responsible for	the themed styles on  Windows  XP  and	Vista.
       This  factory  permits any of the Visual	Styles parts to	be declared as
       Ttk elements that can then be included in a style layout	to modify  the
       appearance of Ttk widgets.

       className  and  partId  are  required parameters	and specify the	Visual
       Styles class and	part as	given  in  the	Microsoft  documentation.  The
       stateMap	 may be	provided to map	Ttk states to Visual Styles API	states
       (see STATE MAP).

       Valid options are:

       -padding	padding
	      Specify the element's interior padding.  padding is a list of up
	      to four integers specifying the left, top, right and bottom pad-
	      ding quantities respectively.  If	fewer than four	 elements  are
	      specified,  bottom  defaults to top, right defaults to left, and
	      top defaults to left.  In	other words, a list of	three  numbers
	      specify  the  left,  vertical,  and right	padding; a list	of two
	      numbers specify the horizontal and the vertical padding; a  sin-
	      gle  number  specifies  the  same	padding	all the	way around the
	      widget.  This option may not be mixed with any other options.

       -margins	padding
	      Specifies	the elements exterior padding.	padding	is a  list  of
	      up  to  four integers specifying the left, top, right and	bottom
	      padding quantities respectively.	This option may	not  be	 mixed
	      with any other options.

       -width width
	      Specifies	the height for the element. If this option is set then
	      the Visual Styles	API will not be	queried	 for  the  recommended
	      size or the part.	If this	option is set then -height should also
	      be set. The -width and -height options cannot be mixed with  the
	      -padding or -margins options.

       -height height
	      Specifies	 the  height  of  the  element.	 See  the comments for

       The stateMap parameter is a list	of ttk states  and  the	 corresponding
       Visual  Styles API state	value.	This permits the element appearance to
       respond to changes in the widget	state such as becoming active or being
       pressed.	The list should	be as described	for the	ttk::style map command
       but note	that the last pair in the list should be the default state and
       is  typically  an empty list and	1. Unfortunately all the Visual	Styles
       parts have different state values and these must	be looked up either in
       the  Microsoft  documentation  or  more likely in the header files. The
       original	header to use was tmschema.h, but in more recent  versions  of
       the Windows Development Kit this	is vssym32.h.

       If  no  stateMap	parameter is given there is an implicit	default	map of
       {{} 1}

       Create a	correctly themed close button by  changing  the	 layout	 of  a
       ttk::button(n).	This  uses  the	WINDOW part WP_SMALLCLOSEBUTTON	and as
       documented the states CBS_DISABLED, CBS_HOT, CBS_NORMAL and  CBS_PUSHED
       are mapped from ttk states.
	      ttk::style element create	smallclose vsapi WINDOW	19 \
		  {disabled 4 pressed 3	active 2 {} 1}
	      ttk::style layout	CloseButton {CloseButton.smallclose -sticky news}
	      pack [ttk::button	.close -style CloseButton]

       Change  the appearance of a ttk::checkbutton(n) to use the Explorer pin
       part EBP_HEADERPIN.
	      ttk::style element create	pin vsapi EXPLORERBAR 3	{
		  {pressed !selected} 3
		  {active !selected} 2
		  {pressed selected} 6
		  {active selected} 5
		  {selected} 4
		  {} 1
	      ttk::style layout	Explorer.Pin { -sticky news}
	      pack [ttk::checkbutton .pin -style Explorer.Pin]

       ttk::intro(n), ttk::widget(n), ttk::style(n), ttk_image(n)
