_________________________________________________________________

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 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 abbre-
viation 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. When-
ever 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 coor-
dinates 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.
