watch_closure


Description:

public void watch_closure (Closure closure)

This function essentially limits the life time of the closure to the life time of the object.

That is, when the object is finalized, the closure is invalidated by calling invalidate on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, @ref and unref are added as marshal guards to the closure, to ensure that an extra reference count is held on this during invocation of the closure. Usually, this function will be called on closures that use this this as closure data.

Parameters:

this

GObject restricting lifetime of closure

closure

GClosure to watch
