+ \ingroup misc
+
+ 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.
