ttk_vsapi(n) Tk Themed Widget ttk_vsapi(n)
NAME
ttk_vsapi - Define a Microsoft Visual Styles element
SYNOPSIS
ttk::style element create name vsapi className partId ?stateMap?
?options?
DESCRIPTION
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).
OPTIONS
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. 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
-width.
STATE MAP
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 and 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}
EXAMPLE
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 {Explorer.Pin.pin -sticky
news} pack [ttk::checkbutton .pin -style Explorer.Pin]
