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.

- 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.
- 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 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(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).
- 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.
