Clutter::Units is a data structure holding a logical distance value along with its type, expressed as a value of the Clutter::UnitType enumeration.
It is possible to use Clutter::Units to store a position or a size in units different than pixels, and convert them whenever needed (for instance inside the Clutter::Actor::allocate() virtual function, or inside the Clutter::Actor::get_preferred_width() and Clutter::Actor::get_preferred_height() virtual functions).
A Clutter::Units is represented by a hash reference with two keys, type, holding the unit type; and value, holding the value for the specified type.
The type key can contain one of the following:
The value key must contain a double.
