Detailed Description

The QUrlInfo class stores information about URLs.

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

You can create your own QUrlInfo objects passing in all the relevant information in the constructor, and you can modify a QUrlInfo; for each getter mentioned above there is an equivalent setter. Note that setting values does not affect the underlying resource that the QUrlInfo provides information about; for example if you call setWritable(true) on a read-only resource the only thing changed is the QUrlInfo object, not the resource.

Enumerations

PermissionSpec

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.
