Clipboard.readValueAsync

void readValueAsync(gobject.types.GType type,  int  ioPriority,  gio.cancellable.Cancellable cancellable =  null,  gio.types.AsyncReadyCallback callback =  null)

Asynchronously request the clipboard contents converted to the given type.

When the operation is finished callback will be called. You must then call [gdk.clipboard.Clipboard.readValueFinish] to get the resulting [gobject.value.Value].

For local clipboard contents that are available in the given GType, the value will be copied directly. Otherwise, GDK will try to use funccontent_deserialize_async to convert the clipboard's data.

Parameters

`type`	a `GType` to read
`ioPriority`	the I/O priority of the request
`cancellable`	optional [gio.cancellable.Cancellable] object
`callback`	callback to call when the request is satisfied
