Gdk.Drop.read_value_async

### Method

# Gdk Dropread_value_async

#### Declaration [src]

    void
    gdk_drop_read_value_async (
      GdkDrop* self,
      GType type,
      int io_priority,
      GCancellable* cancellable,
      GAsyncReadyCallback callback,
      gpointer user_data
    )

#### Description [src]

Asynchronously request the drag operation’s contents converted to the given `type`.

For local drag-and-drop operations that are available in the given `GType`, the value will be copied directly. Otherwise, GDK will try to use `gdk_content_deserialize_async()` to convert the data.

This method completes asynchronously. Use `gdk_drop_read_value_finish()` inside the `GAsyncReadyCallback` to obtain the result of the operation.
