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. If
-variable is set to an existing variable, specifying
-value has no effect (the variable value takes
precedence).
- 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.
The class name for a ttk::scale is TScale.
Dynamic states: active.
TProgressbar styling options configurable with
ttk::style are:
-background color
-borderwidth amount
-darkcolor color
-groovewidth amount
-lightcolor color
-sliderwidth amount
-troughcolor color
-troughrelief relief
Some options are only available for specific themes.
See the ttk::style
manual page for information on how to configure ttk styles.
