_________________________________________________________________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 posi‐
tion of the slider over the trough indicating the value of the vari‐
able.
STANDARD OPTIONS-class-cursor-style

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 cor‐
responding to the left or top end of the scale. [-length length] Spec‐
ifies 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 vari‐
able. [-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 manipu‐
lated 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::wid‐
get(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 corre‐
sponding 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::wid‐
get(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.
