15 A ttk::scale widget is typically used to control the numeric value of a
16 linked variable that varies uniformly over some range. A scale displays
17 a slider that can be moved along over a trough, with the relative posi‐
18 tion of the slider over the trough indicating the value of the vari‐
19 able.

28 Command-Line Name:-command
29 Database Name: command
30 Database Class: Command
31 Specifies the prefix of a Tcl command to invoke whenever the
33 scale's value is changed via a widget command. The actual com‐
34 mand consists of this option followed by a space and a real num‐
35 ber indicating the new value of the scale.
36 Command-Line Name:-from
38 Database Name: from
39 Database Class: From
40 A real value corresponding to the left or top end of the scale.
42 Command-Line Name:-length
44 Database Name: length
45 Database Class: Length
46 Specifies the desired long dimension of the scale in screen
48 units (i.e. any of the forms acceptable to Tk_GetPixels). For
49 vertical scales this is the scale's height; for horizontal
50 scales it is the scale's width.
51 Command-Line Name:-orient
53 Database Name: orient
54 Database Class: Orient
55 Specifies which orientation whether the widget should be laid
57 out horizontally or vertically. Must be either horizontal or
58 vertical or an abbreviation of one of these.
59 Command-Line Name:-to
61 Database Name: to
62 Database Class: To
63 Specifies a real value corresponding to the right or bottom end
65 of the scale. This value may be either less than or greater
66 than the -from option.
67 Command-Line Name:-value
69 Database Name: value
70 Database Class: Value
71 Specifies the current floating-point value of the variable.
73 Command-Line Name:-variable
75 Database Name: variable
76 Database Class: Variable
77 Specifies the name of a global variable to link to the scale.
79 Whenever the value of the variable changes, the scale will
80 update to reflect this value. Whenever the scale is manipulated
81 interactively, the variable will be modified to reflect the
82 scale's new value.
83
85 pathName cget option
86 Returns the current value of the specified option; see ttk::wid‐
87 get(n).
88 pathName configure ?option? ?value option value ...?
90 Modify or query widget options; see ttk::widget(n).
91 pathName get ?x y?
93 Get the current value of the -value option, or the value corre‐
94 sponding to the coordinates x,y if they are specified. X and y
95 are pixel coordinates relative to the scale widget origin.
96 pathName identify x y
98 Returns the name of the element at position x, y. See ttk::wid‐
99 get(n).
100 pathName instate statespec ?script?
102 Test the widget state; see ttk::widget(n).
103 pathName set value
105 Set the value of the widget (i.e. the -value option) to value.
106 The value will be clipped to the range given by the -from and
107 -to options. Note that setting the linked variable (i.e. the
108 variable named in the -variable option) does not cause such
109 clipping.
110 pathName state ?stateSpec?
112 Modify or query the widget state; see ttk::widget(n).
113
115 pathName coords ?value?
116 Get the coordinates corresponding to value, or the coordinates
117 corresponding to the current value of the -value option if value
118 is omitted.
