gtk:drag-source-set-icon-stock (widget stock)

widget -- a gtk:widget object
stock -- a string with the ID of the stock icon to use

Sets the icon that will be used for drags from a particular source to a stock icon. The gtk:drag-source-set-icon-stock function has been deprecated since version 3.10 and should not be used in newly written code. Use the gtk:drag-source-set-icon-name function instead.
