gtk:entry-completion-popup-set-width (object)

object -- a gtk:entry-completion object
setting -- true to make the width of the popup the same as the text entry

The accessor for the popup-set-width slot of the gtk:entry-completion class gets or sets whether the completion popup window will be resized to the width of the text entry. The gtk:entry-completion implementation is deprecated since 4.10. This object will be removed in GTK 5.
