Description

The GtkConstraintTarget interface is implemented by objects that can be used as source or target in GtkConstraints.

Besides GtkWidget, it is also implemented by GtkConstraintGuide.

class (GObject o, IsDescendantOf ConstraintTarget o) => IsConstraintTarget o Source #

Type class for types which can be safely cast to ConstraintTarget, for instance with toConstraintTarget.

toConstraintTarget :: (MonadIO m, IsConstraintTarget o) => o -> m ConstraintTarget Source #

Cast to ConstraintTarget, for types for which this is known to be safe. For general casts, use castTo.
