struct Gtk::DropTarget::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 is responsible for using the given @value and performing the drop operation.

Defined in:

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