gtk:scrolled-window-max-content-width (object)

object -- a gtk:scrolled-window widget
width -- an integer for the maximum content width

The accessor for the max-content-width slot gets or sets the maximum content width that the scrolled window should keep visible. The scrolled window will grow up to this width before it starts scrolling the content.

It is a programming error to set the maximum content width to a value smaller than the min-content-width value.
