| * @short_description: The content of a #WebKitWebView |
| * |
| * A #WebKitWebView contains a main #WebKitWebFrame. A #WebKitWebFrame |
| * contains the content of one URI. The URI and name of the frame can |
| * be retrieved, the load status and progress can be observed using the |
| * signals and can be controlled using the methods of the #WebKitWebFrame. |
| * A #WebKitWebFrame can have any number of children and one child can |
| * be found by using #webkit_web_frame_find_frame. |
| * |
| * <informalexample><programlisting> |
| * /<!-- -->* Get the frame from the #WebKitWebView *<!-- -->/ |
| * WebKitWebFrame *frame = webkit_web_view_get_main_frame (WEBKIT_WEB_VIEW(my_view)); |
