Дополнительные унаследованные членыПодробное описаниеThe QFileOpenEvent class provides an event that will be sent when there is a request to open a file or a URL. File open events will be sent to the QApplication::instance() when the operating system requests that a file or URL should be opened. This is a high-level event that can be caused by different user actions depending on the user's desktop environment; for example, double clicking on an file icon in the Finder on Mac OS X. This event is only used to notify the application of a request. It may be safely ignored. Note: This class is currently supported for Mac OS X and Symbian only. Описание функций-членовQString QFileOpenEvent::file () constReturns the file that is being opened. bool QFileOpenEvent::openFile ( QFile & file, QIODevice::OpenMode flags ) constOpens a QFile on the file referenced by this event in the mode specified by flags. Возвращает true в случае успеха; при неудаче возвращается false. This is necessary as some files cannot be opened by name, but require specific information stored in this event. For example, if this QFileOpenEvent contains a request to open a Symbian data caged file, the QFile could only be opened from the Symbian RFile used in the construction of this event. Эта функция была введена в Qt 4.8. QUrl QFileOpenEvent::url () constReturns the url that is being opened. Эта функция была введена в Qt 4.6. |
