struct Gtk::DropTarget::AcceptSignal
- Gtk::DropTarget::AcceptSignal
- GObject::Signal
- Struct
- Value
- Object
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.
