C++ (Cpp) hasShadowRoot Examples

Example #1

File: ShadowTree.cpp Project: Moondee/Artemis

void ShadowTree::removeAllShadowRoots()
{
    if (!hasShadowRoot())
        return;

    // Dont protect this ref count.
    Element* shadowHost = host();

    while (RefPtr<ShadowRoot> oldRoot = m_shadowRoots.removeHead()) {
        InspectorInstrumentation::willPopShadowRoot(shadowHost, oldRoot.get());
        shadowHost->document()->removeFocusedNodeOfSubtree(oldRoot.get());

        if (oldRoot->attached())
            oldRoot->detach();

        oldRoot->setShadowHost(0);
        oldRoot->setPrev(0);
        oldRoot->setNext(0);
        shadowHost->document()->adoptIfNeeded(oldRoot.get());
        ChildNodeRemovalNotifier(shadowHost).notify(oldRoot.get());
    }

    if (shadowHost->attached())
        shadowHost->attachChildrenLazily();
}

Example #2

File: HTMLProgressElement.cpp Project: CannedFish/deepin-webkit

void HTMLProgressElement::createShadowSubtree()
{
    ASSERT(!hasShadowRoot());

    RefPtr<ProgressBarElement> bar = ProgressBarElement::create(document());
    m_value = ProgressValueElement::create(document());
    bar->appendChild(m_value, ASSERT_NO_EXCEPTION);

    RefPtr<ShadowRoot> root = ShadowRoot::create(this, ShadowRoot::CreatingUserAgentShadowRoot, ASSERT_NO_EXCEPTION);
    root->appendChild(bar, ASSERT_NO_EXCEPTION);
}

Example #3

File: SVGTRefElement.cpp Project: xiaolu31/webkit-node

void SVGTRefElement::updateReferencedText()
{
    String textContent;
    if (Element* target = SVGURIReference::targetElementFromIRIString(href(), document()))
        textContent = target->textContent();

    ASSERT(hasShadowRoot());
    ShadowRoot* root = shadowTree()->oldestShadowRoot();
    if (!root->firstChild())
        root->appendChild(SVGShadowText::create(document(), textContent), ASSERT_NO_EXCEPTION);
    else
        root->firstChild()->setTextContent(textContent, ASSERT_NO_EXCEPTION);
}

Example #4

File: SVGTRefElement.cpp Project: xiaolu31/webkit-node

    ASSERT(hasShadowRoot());
    Node* container = shadowTree()->oldestShadowRoot()->firstChild();
    if (container)
        container->setTextContent(emptyContent, ignore);

    // Mark the referenced ID as pending.
    String id;
    SVGURIReference::targetElementFromIRIString(href(), document(), &id);
    if (!hasPendingResources() && !id.isEmpty())
        document()->accessSVGExtensions()->addPendingResource(id, this);
}
