+ * @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
