Method Detail

deleteChildren

boolean deleteChildren(RadComponent parent,
                       java.util.List<RadComponent> deleted)
                throws java.lang.Exception

Called when one or more children are about to be deleted by the user.

Parameters:

parent - the parent of the deleted children (which still contains the children since this method is called before the deletion is performed)

deleted - a nonempty list of children about to be deleted

Returns:

true if the children have been fully deleted by this participant; false if normal deletion should resume. Note that even though an implementation may return false from this method, that does not mean it did not perform any work. For example, a RelativeLayout handler could remove constraints pointing to now deleted components, but leave the overall deletion of the elements to the core designer.

Throws:

java.lang.Exception
