set_justify
Description:
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 [ctor@Gtk.Label.new]. If you instead want to set the alignment of the label as a whole, use [method@Gtk.Widget.set_halign] instead. [method@Gtk.Label.set_justify] has no effect on labels containing only a single line.
Parameters:
| this |
a `GtkLabel` |
| jtype |
a `GtkJustification` |
