Connect to DragLeave signal.

The ::drag-leave signal is emitted on the drop site when the cursor leaves the widget. A typical reason to connect to this signal is to undo things done in #GtkWidget::drag-motion, e.g. undo highlighting with [gtk.widget.Widget.dragUnhighlight].

Likewise, the #GtkWidget::drag-leave signal is also emitted before the ::drag-drop signal, for instance to allow cleaning up of a preview item created in the #GtkWidget::drag-motion signal handler.

Parameters

`callback`	signal callback delegate or function to connect `void callback(gdk.drag_context.DragContext context, uint time, gtk.widget.Widget widget)` `context` the drag context (optional) `time` the timestamp of the motion event (optional) `widget` the instance the signal is connected to (optional)
`after`	Yes.After to execute callback after default handler, No.After to execute before (default)

Returns

Signal ID
