struct Gtk::DropTarget::AcceptSignal

Overview

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 Gtk::DropTarget#reject or ultimately by returning false from a 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 Gtk::DropTarget#preload property should be set and the value should be inspected via the ::notify:value signal, calling Gtk::DropTarget#reject if required.
