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.  If -variable is set to
              an existing variable, specifying -value has no effect  (the  variable  value  takes
              precedence).

       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(3tk).

       pathName configure ?option? ?value option value ...?
              Modify or query widget options; see ttk::widget(3tk).

       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(3tk).

       pathName instate statespec ?script?
              Test the widget state; see ttk::widget(3tk).

       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(3tk).

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.

STYLING OPTIONS
