Description

A variant of GtkClosureExpression using a C closure.

Synopsis

toCClosureExpression :: (MonadIO m, IsCClosureExpression o) => o -> m CClosureExpression
cClosureExpressionNew :: (HasCallStack, MonadIO m) => GType -> Maybe ClosureMarshal -> [Expression] -> Callback -> m CClosureExpression

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

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 CClosureExpression	Returns: a new `GtkExpression`

Creates a GtkExpression that calls callback_func when it is evaluated.

This function is a variant of closureExpressionNew that creates a GClosure by calling g_cclosure_new() with the given callback_func, user_data and user_destroy.
