gtk:cell-renderer-text-wrap-width (object)

object -- a gtk:cell-renderer-text object
width -- an integer for the minimum width at which text is wrapped

The accessor for the wrap-width slot of the gtk:cell-renderer-text class gets or sets the minimum width at which the text is wrapped. The wrap-mode property can be used to influence at what character positions the line breaks can be placed. Setting the width argument to -1 turns wrapping off. The gtk:cell-renderer-text implementation is deprecated since 4.10. Please do not use it in newly written code.
