| @class wxDataSchemeFSHandler | ||
| File system handler for "data" URI scheme (RFC 2397). | ||
| URI syntax: @c "data:[<mediatype>][;base64],<data>". | ||
| The handler makes the data, included (encoded) into URI, available for | ||
| components that use the wxFileSystem infrastructure. | ||
| To make available for usage it should be registered somewhere within an | ||
| initialization procedure: | ||
| @code | ||
| wxFileSystem::AddHandler(new wxDataSchemeFSHandler); | ||
| @endcode | ||
| @since 3.3.0 | ||
