示例1: styleProperty

QString QWebElement::styleProperty(const QString &name, StyleResolveStrategy strategy) const
{
    if (!m_element || !m_element->isStyledElement())
        return QString();

    int propID = cssPropertyID(name);

    if (!propID)
        return QString();

    CSSStyleDeclaration* style = static_cast<StyledElement*>(m_element)->style();

    if (strategy == InlineStyle)
        return style->getPropertyValue(propID);

    if (strategy == CascadedStyle) {
        if (style->getPropertyPriority(propID))
            return style->getPropertyValue(propID);

        // We are going to resolve the style property by walking through the
        // list of non-inline matched CSS rules for the element, looking for
        // the highest priority definition.

        // Get an array of matched CSS rules for the given element sorted
        // by importance and inheritance order. This include external CSS
        // declarations, as well as embedded and inline style declarations.

        DOMWindow* domWindow = m_element->document()->frame()->domWindow();
        if (RefPtr<CSSRuleList> rules = domWindow->getMatchedCSSRules(m_element, "")) {
            for (int i = rules->length(); i > 0; --i) {
                CSSStyleRule* rule = static_cast<CSSStyleRule*>(rules->item(i - 1));

                if (rule->style()->getPropertyPriority(propID))
                    return rule->style()->getPropertyValue(propID);

                if (style->getPropertyValue(propID).isEmpty())
                    style = rule->style();
            }
        }

        return style->getPropertyValue(propID);
    }

    if (strategy == ComputedStyle) {
        if (!m_element || !m_element->isStyledElement())
            return QString();

        int propID = cssPropertyID(name);
