Sets the alignment of the lines in the text of the label relative to
each other. %GTK_JUSTIFY_LEFT is the default value when the widget is
first created with gtk_label_new(). If you instead want to set the
alignment of the label as a whole, use gtk_widget_set_halign() instead.
gtk_label_set_justify() has no effect on labels containing only a
single line.
