ttk::scale - Create and manipulate a scale widget








ttk::scale pathName ?options...?










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.

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








[-command 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.
    [-from from] A real value
    corresponding to the left or top end of the scale.
    [-length 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.
    [-orient 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. [-to 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. [-value value] Specifies the
    current floating-point value of the variable.
    [-variable 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.









  

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

  

  
Modify or query widget options; see ttk::widget(n).

  

  
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.

  

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

  

  
Test the widget state; see ttk::widget(n).

  

  
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.

  

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











  

  
Get the coordinates corresponding to value, or the coordinates
      corresponding to the current value of the -value option if
      value is omitted.
