ttk::scale(n)                                 Tk Themed Widget                                 ttk::scale(n)

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 num-ber number
              ber 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 vari-able variable
              able 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.
