 /**
  * @class KIO::AskUserActionInterface askuseractioninterface.h <KIO/AskUserActionInterface>
  *
  * @brief The AskUserActionInterface class allows a KIO::Job to prompt the user
  * for a decision when e.g.\ copying directories/files and there is a conflict
  * (e.g.\ a file with the same name already exists at the destination).
  *
  * The methods in this interface are similar to their counterparts in
  * KIO::JobUiDelegateExtension, the main difference is that AskUserActionInterface
  * shows the dialogs using show() or open(), rather than exec(), the latter creates
  * a nested event loop which could lead to crashes.
  *
  * @sa KIO::JobUiDelegateExtension
