• GObject::Signal
• Struct

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.

Defined in:

lib/gi-crystal/src/auto/gtk-4.0/drop_target_async.cr
