Toggles line wrapping within the `GtkLabel` widget.
true makes it break lines if text exceeds the widget’s size. false lets the text get cut off by the edge of the widget if it exceeds the widget size.
Note that setting line wrapping to true does not make the label wrap at its parent container’s width, because GTK widgets conceptually can’t make their requisition depend on the parent container’s size. For a label that wraps at a specific position, set the label’s width using [[email protected]_size_request].
