QWebDatabase Class Reference
[QtWebKit module]

Detailed Description

The QWebDatabase class provides access to HTML 5 databases created with JavaScript.

The upcoming HTML 5 standard includes support for SQL databases that web sites can create and access on a local computer through JavaScript. QWebDatabase is the C++ interface to these databases.

To get access to all databases defined by a security origin, use QWebSecurityOrigin::databases(). Each database has an internal name(), as well as a user-friendly name, provided by displayName().

WebKit uses SQLite to create and access the local SQL databases. The location of the database file in the local file system is returned by fileName(). You can access the database directly through the QtSql database module.

For each database the web site can define an expectedSize(). The current size of the database in bytes is returned by size().

For more information refer to the HTML 5 Draft Standard.
