GI.Gtk.Objects.ConstraintGuide

A ConstraintGuide is an invisible layout element that can be used by widgets inside a ConstraintLayout as a source or a target of a Constraint. Guides can be used like guidelines or as flexible space.

Unlike a Widget, a ConstraintGuide will not be drawn.

constructConstraintGuideMaxHeight :: (IsConstraintGuide o, MonadIO m) => Int32 -> m (GValueConstruct o)

Get the value of the “max-height” property. When overloading is enabled, this is equivalent to

get constraintGuide #maxHeight

Set the value of the “max-height” property. When overloading is enabled, this is equivalent to

set constraintGuide [ #maxHeight := value ]
