connectDrop
Emitted on the drop site when the user drops the data onto the widget.
The signal handler must determine whether the pointer position is in a drop zone or not. If it is not in a drop zone, it returns false and no further processing is necessary.
Otherwise, the handler returns true. In this case, this handler will accept the drop. The handler must ensure that method@Gdk.Drop.finish is called to let the source know that the drop is done. The call to method@Gdk.Drop.finish must only be done when all data has been received.
To receive the data, use one of the read functions provided by class@Gdk.Drop such as method@Gdk.Drop.read_async or method@Gdk.Drop.read_value_async.
Parameters
A combination of ConnectFlags
the Callback to connect. Params: drop the GdkDrop; x the x coordinate of the current pointer position; y the y coordinate of the current pointer position. Returns whether the drop is accepted at the given pointer position
