DropTarget.addOnAccept

Emitted on the drop site when a drop operation is about to begin.

If the drop is not accepted, %FALSE will be returned and the drop target will ignore the drop. If %TRUE is returned, the drop is accepted for now but may be rejected later via a call to [method@Gtk.DropTarget.reject] or ultimately by returning %FALSE from a [signal@Gtk.DropTarget::drop] handler.

The default handler for this signal decides whether to accept the drop based on the formats provided by the @drop.

If the decision whether the drop will be accepted or rejected depends on the data, this function should return %TRUE, the [property@Gtk.DropTarget:preload] property should be set and the value should be inspected via the ::notify:value signal, calling [method@Gtk.DropTarget.reject] if required.
