class (BoxedPtr o, TypedObject o, IsDescendantOf CClosureExpression o) => IsCClosureExpression o

Type class for types which can be safely cast to CClosureExpression, for instance with toCClosureExpression.

toCClosureExpression :: (MonadIO m, IsCClosureExpression o) => o -> m CClosureExpression

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

Arguments

:: (HasCallStack, MonadIO m)

=> GType

valueType: the type of the value that this expression evaluates to

-> Maybe ClosureMarshal

marshal: marshaller used for creating a closure

-> [Expression]

params: expressions for each parameter

-> Callback

callbackFunc: callback used for creating a closure

-> m Expression

Returns: a new Expression

This function is a variant of closureExpressionNew that creates a Closure by calling g_cclosure_new() with the given callbackFunc, userData and userDestroy.
