Method Details

onDrop

boolean onDrop(@Nonnull
 Drop drop,
 double x,
 double y)

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:

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
