Class

GdkContentProvider

Description [src]

class Gdk.ContentProvider : GObject.Object {
  parent: GObject
}

A GdkContentProvider is used to provide content for the clipboard or for drag-and-drop operations in a number of formats.

To create a GdkContentProvider, use gdk_content_provider_new_for_value() or gdk_content_provider_new_for_bytes().

GDK knows how to handle common text and image formats out-of-the-box. See GdkContentSerializer and GdkContentDeserializer if you want to add support for application-specific data formats.
