Descripción detallada

The QUrlInfo class stores information about URLs.

This class is just a container for storing information about URLs, which is why all information must be passed in the constructor.

Unless you're reimplementing a network protocol you're unlikely to create QUrlInfo objects yourself, but you may receive QUrlInfo objects from functions, e.g. QUrlOperator::info().

The information that can be retrieved includes name(), permissions(), owner(), group(), size(), lastModified(), lastRead(), isDir(), isFile(), isSymLink(), isWritable(), isReadable() and isExecutable().

Documentación de las enumeraciones miembro de la clase

enum QUrlInfo::PermissionSpec

This enum is used by the permissions() function to report the permissions of a file.

ReadOwner The file is readable by the owner of the file. WriteOwner The file is writable by the owner of the file. ExeOwner The file is executable by the owner of the file. ReadGroup The file is readable by the group. WriteGroup The file is writable by the group. ExeGroup The file is executable by the group. ReadOther The file is readable by anyone. WriteOther The file is writable by anyone. ExeOther The file is executable by anyone.

Documentación del constructor y destructor

QUrlInfo::QUrlInfo

(

)

Constructs an invalid QUrlInfo object with default values.

Ver también:

isValid()

QUrlInfo::QUrlInfo	(	const QUrlOperator &	path,
		const QString &	file
	)

Constructs a QUrlInfo object with information about the file file in the path. It tries to find the information about the file in the QUrlOperator path.

If the information is not found, this constructor creates an invalid QUrlInfo, i.e. isValid() returns FALSE. You should always check if the URL info is valid before relying on the return values of any getter functions.

If file is empty, it defaults to the QUrlOperator path, i.e. to the directory.

QUrlInfo::QUrlInfo

		bool	isReadable,
		bool	isExecutable
	)

Constructs a QUrlInfo object by specifying all the URL's information.

The information that is passed is the name, file permissions, owner and group and the file's size. Also passed is the lastModified date/time and the lastRead date/time. Flags are also passed, specifically, isDir, isFile, isSymLink, isWritable, isReadable and isExecutable.
