C++ QVersitDocument::type方法代码示例

/*!
 * Converts \a document into a corresponding list of QOrganizerItems.  After calling this, the
 * converted organizer items can be retrieved by calling items().
 *
 * Returns true on success.  The document should contain at least one subdocument.  In the
 * importing process, each subdocument roughly corresponds to a QOrganizerItem.  If any of the
 * subdocuments cannot be imported as organizer items (eg. they don't conform to the iCalendar
 * format), false is returned and errorMap() will return a list describing the errors that occurred.
 * The successfully imported items will still be available via items().
 *
 * \sa items(), errorMap()
