ParamSpecExpressionProtocol
public protocol ParamSpecExpressionProtocol : ParamSpecProtocol
A GParamSpec
for properties holding a GtkExpression
.
The ParamSpecExpressionProtocol
protocol exposes the methods and properties of an underlying GtkParamSpecExpression
instance.
The default implementation of these can be found in the protocol extension below.
For a concrete class that implements these methods and properties, see ParamSpecExpression
.
Alternatively, use ParamSpecExpressionRef
as a lighweight, unowned
reference if you already have an instance you just want to use.
