class Gdk::ContentDeserializer

Overview

A Gdk::ContentDeserializer is used to deserialize content received via inter-application data transfers.

The Gdk::ContentDeserializer transforms serialized content that is identified by a mime type into an object identified by a GType.

GTK provides serializers and deserializers for common data types such as text, colors, images or file lists. To register your own deserialization functions, use #content_register_deserializer.

Also see Gdk::ContentSerializer.

Instance Method Detail

def ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.


def cancellable : Gio::Cancellable | Nil #

Gets the cancellable for the current operation.

This is the GCancellable that was passed to Gdk::content_deserialize_async.


[View source]
def gtype : UInt64 #

Gets the GType to create an instance of.


[View source]
def hash(hasher) #
Description copied from class Reference

See Object#hash(hasher)


def input_stream : Gio::InputStream #

Gets the input stream for the current operation.

This is the stream that was passed to Gdk::content_deserialize_async.


[View source]
def mime_type : String #

Gets the mime type to deserialize from.


[View source]
def priority : Int32 #

Gets the I/O priority for the current operation.

This is the priority that was passed to Gdk::content_deserialize_async.


[View source]
def return_error(error : GLib::Error) : Nil #

Indicate that the deserialization has ended with an error.

This function consumes error.


[View source]
def return_success : Nil #

Indicate that the deserialization has been successfully completed.


[View source]
def set_task_data(data : Pointer(Void) | Nil, notify : GLib::DestroyNotify) : Nil #

Associate data with the current deserialization operation.


[View source]
def task_data : Pointer(Void) | Nil #

Gets the data that was associated with the current operation.

See Gdk::ContentDeserializer#task_data=.


[View source]
def user_data : Pointer(Void) | Nil #

Gets the user data that was passed when the deserializer was registered.


[View source]
def value : GObject::Value #

Gets the GValue to store the deserialized object in.
