alias GObject::BindingTransformFunc
Overview
A function to be called to transform @from_value to @to_value.
If this is the @transform_to function of a binding, then @from_value is the @source_property on the @source object, and @to_value is the @target_property on the @target object. If this is the @transform_from function of a %G_BINDING_BIDIRECTIONAL binding, then those roles are reversed.
