QAbstractUriResolver Class

The QAbstractUriResolver class 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. QAbstractUriResolver::resolve() provides this functionality. More...

Detailed Description

The QAbstractUriResolver class 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. QAbstractUriResolver::resolve() provides this functionality.

For example, one could write a QAbstractUriResolver subclass 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 QAbstractUriResolver subclass 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.
