struct Gtk::DropTargetAsync::DropSignal

Overview

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 Gdk::Drop#finish is called to let the source know that the drop is done. The call to 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 Gdk#Drop such as Gdk::Drop#read_async or Gdk::Drop#read_value_async.
