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



  

  
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).








INTERNAL COMMANDS



  

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