ttk::scale pathName ?options...?
______________________________________________________________________________
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
-takefocus
See the ttk_widget manual entry for details on the standard options.
WIDGET-SPECIFIC OPTIONS
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 com-
mand consists of this option followed by a space and a real num-
ber 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.
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.
