QAbstractUriResolverclass is a callback interface for resolving Uniform Resource Identifiers. A Uniform Resource Identifier (URI) is a string that uniquely identifies a resource. URIs are versatile global identifiers. It is often useful to transform a URI that identifies something logical into a URI that locates something physical (a URL), or to simply map a URI to a different URI.
resolve()provides this functionality. More…
For example, one could write a
QAbstractUriResolversubclass that rewrites library ISBN number URIs as book title URLs, e.g., urn:isbn:0-345-33973-8 would be rewritten as file:///books/returnOfTheKing.doc . Or a
QAbstractUriResolversubclass could be written for a web browser to let the web browser protect the user’s private files by mapping incoming requests for them to null URIs.

The caller guarantees that both
baseURIare valid, and that
relativecan be relative, absolute, or empty.
QUrlcan be a default constructed
QUrl. If it is not a default constructed
QUrl, it will be absolute and valid. If a default constructed
QUrlis returned, it means the
relativeURI was not accepted to be resolved.
If the reimplemented function decides it has nothing to do about resolving the
relativeURI, it should simply return the
relativeURI resolved against the
