Label.setJustify

Sets the alignment of the lines in the text of the label relative to each other. [gtk.types.Justification.Left] is the default value when the widget is first created with [gtk.label.Label.new_]. If you instead want to set the alignment of the label as a whole, use [gtk.widget.Widget.setHalign] instead. [gtk.label.Label.setJustify] has no effect on labels containing only a single line.
