NAME
       ttk::scale - Create and manipulate a scale widget

SYNOPSIS
       ttk::scale pathName ?options...?
______________________________________________________________________________

DESCRIPTION
       A ttk::scale widget is typically used to control the numeric value of a
       linked variable that varies uniformly over some range. A scale displays
       a slider that can be moved along over a trough, with the relative
       position of the slider over the trough indicating the value of the
       variable.

STANDARD OPTIONS
       -class                -cursor              -style
       -takefocus

       See the ttk_widget manual entry for details on the standard options.

WIDGET-SPECIFIC OPTIONS
       Command-Line Name:-command
       Database Name:  command
       Database Class: Command

              Specifies the prefix of a Tcl command to invoke whenever the
              scale's value is changed via a widget command. The actual
              command consists of this option followed by a space and a real
              number indicating the new value of the scale.

       Command-Line Name:-from
       Database Name:  from
       Database Class: From

              A real value corresponding to the left or top end of the scale.

       Command-Line Name:-length
       Database Name:  length
       Database Class: Length

              Specifies the desired long dimension of the scale in screen
              units (i.e. any of the forms acceptable to Tk_GetPixels). For
              vertical scales this is the scale's height; for horizontal
              scales it is the scale's width.

       Command-Line Name:-orient
       Database Name:  orient
       Database Class: Orient

              Specifies which orientation whether the widget should be laid
              out horizontally or vertically. Must be either horizontal or
              vertical or an abbreviation of one of these.

       Command-Line Name:-to
       Database Name:  to
       Database Class: To

              Specifies a real value corresponding to the right or bottom end
              of the scale.  This value may be either less than or greater
              than the -from option.

       Command-Line Name:-value
       Database Name:  value
       Database Class: Value

              Specifies the current floating-point value of the variable.

       Command-Line Name:-variable
       Database Name:  variable
       Database Class: Variable

              Specifies the name of a global variable to link to the scale.
              Whenever the value of the variable changes, the scale will
              update to reflect this value.  Whenever the scale is manipulated
              interactively, the variable will be modified to reflect the
              scale's new value.

WIDGET COMMAND
       pathName cget option
              Returns the current value of the specified option; see
              ttk::widget(n).

       pathName configure ?option? ?value option value ...?
              Modify or query widget options; see ttk::widget(n).

       pathName get ?x y?
              Get the current value of the -value option, or the value
              corresponding to the coordinates x,y if they are specified. X
              and y are pixel coordinates relative to the scale widget origin.

       pathName identify x y
              Returns the name of the element at position x, y.  See
              ttk::widget(n).

       pathName instate statespec ?script?
              Test the widget state; see ttk::widget(n).

       pathName set value
              Set the value of the widget (i.e. the -value option) to value.
              The value will be clipped to the range given by the -from and
              -to options. Note that setting the linked variable (i.e. the
              variable named in the -variable option) does not cause such
              clipping.

       pathName state ?stateSpec?
              Modify or query the widget state; see ttk::widget(n).

INTERNAL COMMANDS
       pathName coords ?value?
              Get the coordinates corresponding to value, or the coordinates
              corresponding to the current value of the -value option if value
              is omitted.
