/**
 * SECTION:hdy-window-handle
 * @short_description: A bin that acts like a titlebar.
 * @Title: HdyWindowHandle
 * @See_also: #HdyApplicationWindow, #HdyHeaderBar, #HdyWindow
 *
 * HdyWindowHandle is a #GtkBin subclass that can be dragged to move its
 * #GtkWindow, and handles right click, middle click and double click as
 * expected from a titlebar. This is particularly useful with #HdyWindow or
 * #HdyApplicationWindow.
 *
 * It isn't necessary to use #HdyWindowHandle if you use #HdyHeaderBar.
 *
 * It can be safely nested or used in the actual window titlebar.
 *
 * # CSS nodes
 *
 * #HdyWindowHandle has a single CSS node with name windowhandle.
 *
 * Since: 1.0
