From f0a3c95cfc4a5595f930cd5dd14d6cbbf1f85312 Mon Sep 17 00:00:00 2001 From: rsk1994 Date: Sat, 31 May 2014 09:07:42 +0530 Subject: tableSectionElement Rev.2 && tableCellElement Rev.4 && tableElement Rev.1 && tableRowElement Rev.1 && DOMTSHandler(Test Suite) Revised and implemented inefficient ways to produce correct .c's && other minor bg fixes in HTMLCollection... Tests expecting 2nd attribute of dom_html_collection_get_length to be of type int32_t aren't enabled yet. Will be done in a later commit. --- src/html/html_table_element.c | 740 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 740 insertions(+) (limited to 'src/html/html_table_element.c') diff --git a/src/html/html_table_element.c b/src/html/html_table_element.c index 2e182d5..0f27fd3 100644 --- a/src/html/html_table_element.c +++ b/src/html/html_table_element.c @@ -3,5 +3,745 @@ * Licensed under the MIT License, * http://www.opensource.org/licenses/mit-license.php * Copyright 2009 Bo Yang + * Copyright 2014 Rupinder Singh Khokhar */ +#include +#include + +#include + +#include "html/html_document.h" +#include "html/html_table_element.h" +#include "html/html_tablecaption_element.h" +#include "html/html_tablesection_element.h" +#include "html/html_tablerow_element.h" +#include "html/html_collection.h" + +#include "core/node.h" +#include "core/attr.h" +#include "utils/utils.h" + +static struct dom_element_protected_vtable _protect_vtable = { + { + DOM_NODE_PROTECT_VTABLE_HTML_TABLE_ELEMENT + }, + DOM_HTML_TABLE_ELEMENT_PROTECT_VTABLE +};
