DClosure

DClosure is a wrapper around the gobject library's GClosure with special handling for marshalling D delegates and function pointers as callbacks.

Closures are central to the concept of asynchronous signal delivery which is widely used throughout GTK+ and GNOME applications. A closure is an abstraction, a generic representation of a callback.

class DClosure : Closure {

GClosure* getDClosureStruct(bool transferOwnership);

this(GClosure* gClosure, bool ownedRef);

this(T callback, bool swap);

static void d_closure_marshal(GClosure* closure, GValue* return_value, uint n_param_values, GValue* param_values, void* invocation_hint, void* marshal_data);

}

Constructors

this this(GClosure* gClosure, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(T callback, bool swap): Create a new Closure that will call callback when it's invoked.

Functions

Static functions

d_closure_marshal void d_closure_marshal(GClosure* closure, GValue* return_value, uint n_param_values, GValue* param_values, void* invocation_hint, void* marshal_data): Undocumented in source. Be warned that the author may not have intended to support it.

Inherited Members

From Closure

gClosure GClosure* gClosure;: the main Gtk struct
ownedRef bool ownedRef;: Undocumented in source.
getClosureStruct GClosure* getClosureStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
~this ~this(): Undocumented in source.
getType GType getType()
addFinalizeNotifier void addFinalizeNotifier(void* notifyData, GClosureNotify notifyFunc): Registers a finalization notifier which will be called when the reference count of @closure goes down to 0.
addInvalidateNotifier void addInvalidateNotifier(void* notifyData, GClosureNotify notifyFunc): Registers an invalidation notifier which will be called when the @closure is invalidated with g_closure_invalidate().
addMarshalGuards void addMarshalGuards(void* preMarshalData, GClosureNotify preMarshalNotify, void* postMarshalData, GClosureNotify postMarshalNotify): Adds a pair of notifiers which get invoked before and after the closure callback, respectively.
invalidate void invalidate(): Sets a flag on the closure to indicate that its calling environment has become invalid, and thus causes any future invocations of g_closure_invoke() on this @closure to be ignored.
invoke void invoke(Value returnValue, Value[] paramValues, void* invocationHint): Invokes the closure, i.e. executes the callback represented by the @closure.
doref alias doref = ref_: Undocumented in source.
ref_ Closure ref_(): Increments the reference count on a closure to force it staying alive while the caller holds a pointer to it.
removeFinalizeNotifier void removeFinalizeNotifier(void* notifyData, GClosureNotify notifyFunc): Removes a finalization notifier.
removeInvalidateNotifier void removeInvalidateNotifier(void* notifyData, GClosureNotify notifyFunc): Removes an invalidation notifier.
setMarshal void setMarshal(GClosureMarshal marshal): Sets the marshaller of @closure.
setMetaMarshal void setMetaMarshal(void* marshalData, GClosureMarshal metaMarshal): Sets the meta marshaller of @closure.
sink void sink(): Takes over the initial ownership of a closure.
unref void unref(): Decrements the reference count of a closure after it was previously incremented by the same caller.
sourceSetClosure void sourceSetClosure(Source source, Closure closure): Set the callback for a source as a #GClosure.
sourceSetDummyCallback void sourceSetDummyCallback(Source source): Sets a dummy callback for @source. The callback will do nothing, and if the source expects a #gboolean return value, it will return %TRUE. (If the source expects any other type of return value, it will return a 0/%NULL value; whatever g_value_init() initializes a #GValue to for that type.)
