35 * @see_also: #WebKitWebView::viewport-attributes-recompute-requested
36 * @see_also: #WebKitWebView::viewport-attributes-changed
38 * #WebKitViewportAttributes offers the viewport properties to user agents to
39 * control the viewport layout. It contains the viewport size, initial scale with limits,
40 * and information about whether a user is able to scale the contents in the viewport.
43 * The #WebKitWebView::viewport-attributes-changed signal will be emitted with #WebKitViewportAttributes
44 * when the viewport attributes are updated in the case of loading web pages contain
45 * the viewport properties and calling webkit_viewport_attributes_recompute.
49 * You should call #webkit_viewport_attributes_recompute to recompute the viewport properties and
50 * override those values in the handler of #WebKitWebView::viewport-attributes-recompute-requested signal.
52 * For more information on the viewport properties, refer to the Safari reference library at
