Detailed Description

Scale widget which can display a numerical scale.

You can associate an InTVar or DoubleVar to its state and a callback to be called when the state of the scale changes.

Common options (see Widgets properties)

  abcolor, bcolor,  borderwidth, command, cursor, font, fcolor, hbcolor,
  hfcolor, relief, state, takefocus, tcolor, variable

Less common options

Constructor & Destructor Documentation

__init__()

def __init__	(		self,
			parent,
			x,
			y,
			w,
			h,
			pad = 0,
			limits = None,
			variable = None,
			command = None
	)

The constructor.

You can specify here the numeric limits of the scale, a Variable object which will be updated at state change and a callback to associate to status change.

Parameters

parent	the widget parent
x,y,w,h,pad	see Placing the widgets
limits	you can specify a duple of numbers (min and max) or a triple (min, max, step)
variable	the Variable object whose value is associated with the button states; here you can specify: None: a DoubleVar is automatically created an IntVar or DoubleVar object
command	see Events and callbacks

Reimplemented from Widget.

Member Function Documentation

get_value()

def get_value

(

self

)

Returns the actual value associated to the scale.

Note

for this class the get_content() method returns an empty string

set_value()

def set_value

(

self

)

Sets actual value associated to the scale and updates the widget.

Note

for this class the set_content() method does nothing.

set_variable()

def set_variable	(		self,
			variable = None,
			from_ = None,
			to_ = None,
			increment = None
	)

Sets the associated tkinter.Variable object and its values when the button is in off and on state.

Only the given values are changed. You should do this in the constructor so you need this only if you want to change them later.
