# along the centerline of the trough that corresponds to value.
# If value is omitted then the scale's current value is used.

# If x and y are omitted, returns the current value of the scale.
# If x and y are specified, they give pixel coordinates within the widget;
# the command returns the scale value corresponding to the given pixel.
# Only one of x or y is used: for horizontal scales y is ignored, and for
# vertical scales x is ignored.
def get(x = None, y = None)
execute(:get, x, y)
end
# Returns a string indicating what part of the scale lies under the
# coordinates given by x and y.
# A return value of slider means that the point is over the slider; trough1
# means that the point is over the portion of the slider above or to the
# left of the slider; and trough2 means that the point is over the portion
# of the slider below or to the right of the slider.
# If the point is not over one of these elements, an empty string is
# returned.

# This command is invoked to change the current value of the scale, and
# hence the position at which the slider is displayed.
# Value gives the new value for the scale.
# The command has no effect if the scale is disabled.
# the button is held down, the action auto-repeats.
