NAME

       ttk::widget - Standard options and commands supported by Tk themed widgets
_________________________________________________________________

DESCRIPTION

       This manual describes common widget options and commands.

STANDARD OPTIONS

       The following options are supported by all Tk themed widgets:

       Command-Line Name:-class
       Database Name:  undefined
       Database Class: undefined

              Specifies  the  window  class.  The class is used when querying the option database
              for the window's other options, to determine the default bindtags for  the  window,
              and  to  select the widget's default layout and style.  This is a read-only option:
              it may only be specified when the window is created, and may not  be  changed  with
              the configure widget command.

       Command-Line Name:-cursor
       Database Name:  cursor
       Database Class: Cursor

              Specifies  the  mouse  cursor  to  be  used  for  the widget.  See Tk_GetCursor and
              cursors(3tk) in the Tk reference manual for the legal values.  If set to the  empty
              string (the default), the cursor is inherited from the parent widget.

       Command-Line Name:-takefocus
       Database Name:  takeFocus
       Database Class: TakeFocus

              Determines  whether the window accepts the focus during keyboard traversal.  Either
              0, 1, a command prefix (to which the widget path  is  appended,  and  which  should
              return  0  or 1), or the empty string.  See options(3tk) in the Tk reference manual
              for the full description.

       Command-Line Name:-style
       Database Name:  style
       Database Class: Style

              May be used to specify a custom widget style.

SCROLLABLE WIDGET OPTIONS

       The following options are supported by widgets that are controllable by a scrollbar.   See
       scrollbar(3tk) for more information

       Command-Line Name:-xscrollcommand
       Database Name:  xScrollCommand
       Database Class: ScrollCommand

              A command prefix, used to communicate with horizontal scrollbars.
              When  the  view  in  the  widget's  window  changes, the widget will generate a Tcl
              command by concatenating the scroll command and two numbers.  Each of  the  numbers
              is  a  fraction  between 0 and 1 indicating a position in the document; 0 indicates
              the beginning, and 1 indicates the end.  The first  fraction  indicates  the  first
              information  in  the  widget that is visible in the window, and the second fraction
              indicates the information just after the last portion that is visible.

              Typically the xScrollCommand option consists of the path name of a scrollbar widget
              followed  by  “set”, e.g.  “.x.scrollbar set”.  This will cause the scrollbar to be
              updated whenever the view in the window changes.

              If this option is set to the empty string (the default), then no  command  will  be
              executed.

       Command-Line Name:-yscrollcommand
       Database Name:  yScrollCommand
       Database Class: ScrollCommand

              A   command  prefix,  used  to  communicate  with  vertical  scrollbars.   See  the
              description of -xscrollcommand above for details.

LABEL OPTIONS

       The following options are supported by labels, buttons, and other button-like widgets:

       Command-Line Name:-text
       Database Name:  text
       Database Class: Text

              Specifies a text string to be displayed inside the  widget  (unless  overridden  by
              -textvariable).

       Command-Line Name:-textvariable
       Database Name:  textVariable
       Database Class: Variable

              Specifies  the  name  of a global variable whose value will be used in place of the
              -text resource.

       Command-Line Name:-underline
       Database Name:  underline
       Database Class: Underline

              If set, specifies the integer index (0-based) of a character to  underline  in  the
              text string.  The underlined character is used for mnemonic activation.

       Command-Line Name:-image
       Database Name:  image
       Database Class: Image

              Specifies  an  image  to display.  This is a list of 1 or more elements.  The first
              element is the default image name.  The rest of the list is a sequence of statespec
              /  value pairs as per style map, specifying different images to use when the widget
              is in a particular state or combination of states.  All images in the  list  should
              have the same size.

       Command-Line Name:-compound
       Database Name:  compound
       Database Class: Compound

              Specifies how to display the image relative to the text, in the case both -text and
              -image are present.  Valid values are:

              text   Display text only.

              image  Display image only.

              center Display text centered on top of image.

              top

              bottom

              left

              right  Display image above, below, left of, or right of the text, respectively.

              none   The default; display the image if present, otherwise the text.

       Command-Line Name:-width
       Database Name:  width
       Database Class: Width

              If greater than zero, specifies how much space, in character  widths,  to  allocate
              for  the  text  label.   If  less than zero, specifies a minimum width.  If zero or
              unspecified, the natural width of the text label is used.

COMPATIBILITY OPTIONS

       Command-Line Name:-state
       Database Name:  state
       Database Class: State

              May be set to normal or disabled to control the disabled  state  bit.   This  is  a
              write-only  option:  setting  it  changes  the  widget  state, but the state widget
              command does not affect the -state option.

COMMANDS

       pathName cget option
              Returns the current value of the configuration option given by option.

       pathName configure ?option? ?value option value ...?
              Query or  modify  the  configuration  options  of  the  widget.   If  one  or  more
              option-value  pairs  are  specified,  then  the  command  modifies the given widget
              option(s) to have the given value(s); in this case the  command  returns  an  empty
              string.   If  option  is  specified  with no value, then the command returns a list
              describing the named option: the elements of the list are the option name, database
              name, database class, default value, and current value.  If no option is specified,
              returns a list describing all of the available options for pathName.

       pathName identify element x y
              Returns the name of the element under the point given by  x  and  y,  or  an  empty
              string if the point does not lie within any element.  x and y are pixel coordinates
              relative to the widget.  Some widgets accept other identify subcommands.

       pathName instate statespec ?script?
              Test the widget's state.  If script is not specified, returns 1 if the widget state
              matches statespec and 0 otherwise.  If script is specified, equivalent to
              if {[pathName instate stateSpec]} script

       pathName state ?stateSpec?
              Modify  or  inquire  widget state.  If stateSpec is present, sets the widget state:
              for each flag in stateSpec, sets the corresponding flag or clears it if prefixed by
              an exclamation point.
              Returns a new state spec indicating which flags were changed:
                     set changes [pathName state spec]
                     pathName state $changes
              will  restore  pathName  to  the  original  state.   If stateSpec is not specified,
              returns a list of the currently-enabled state flags.

WIDGET STATES

       The widget state is a bitmap of independent state flags.  Widget state flags include:

       active The mouse cursor is over the widget and pressing a mouse  button  will  cause  some
              action to occur. (aka “prelight” (Gnome), “hot” (Windows), “hover”).

       disabled
              Widget is disabled under program control (aka “unavailable”, “inactive”)

       focus  Widget has keyboard focus

       pressed
              Widget is being pressed (aka “armed” in Motif).

       selected
              “On”, “true”, or “current” for things like checkbuttons and radiobuttons.

       background
              Windows  and  the  Mac  have  a  notion  of  an “active” or foreground window.  The
              background state is set for widgets in a background window, and cleared  for  those
              in the foreground window.

       readonly
              Widget should not allow user modification.

       alternate
              A widget-specific alternate display format.  For example, used for checkbuttons and
              radiobuttons in the “tristate” or “mixed” state,  and  for  buttons  with  -default
              active.

       invalid
              The  widget's value is invalid.  (Potential uses: scale widget value out of bounds,
              entry widget value failed validation.)

       hover  The mouse cursor is within the widget.  This is similar to the active state; it  is
              used  in  some  themes  for  widgets  that provide distinct visual feedback for the
              active widget in addition to the active element within the widget.

       A state specification or stateSpec is a list of state names, optionally prefixed  with  an
       exclamation point (!)  indicating that the bit is off.

EXAMPLES

              set b [ttk::button .b]

              # Disable the widget:
              $b state disabled

              # Invoke the widget only if it is currently pressed and enabled:
              $b instate {pressed !disabled} { .b invoke }

              # Reenable widget:
              $b state !disabled
