## Bar class

The Bar class is a graphical object representing a squared surface added to a DFrame.

### Creation

There are no constructors for this class. Bars are created with the DFrame addBar method:

var bar = dFrame.addBar(position, title, barStyle):

Some methods implicitly create the default Bar of a DFrame:

var button = dFrame.addButton(parameters)

var menu = dFrame.addMenu(parameters)
