Detailed Description

The 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 only.

Member Function Documentation

QString QFileOpenEvent::file() const

Returns the file that is being opened.

bool QFileOpenEvent::openFile(QFile & file, QIODevice::OpenMode flags) const

Opens a QFile on the file referenced by this event in the mode specified by flags. Returns true if successful; otherwise returns false.

This is necessary as some files cannot be opened by name, but require specific information stored in this event.

This function was introduced in Qt 4.8.

QUrl QFileOpenEvent::url() const

Returns the url that is being opened.

This function was introduced in Qt 4.6.
