C++ (Cpp) LayerChromium::parent Exemples

Exemple #1

void LayerChromium::removeAllChildren()
{
    while (m_children.size()) {
        LayerChromium* layer = m_children[0].get();
        ASSERT(layer->parent());
        layer->removeFromParent();
    }
}

Exemple #2

bool LayerChromium::hasAncestor(LayerChromium* ancestor) const
{
    for (LayerChromium* layer = parent(); layer; layer = layer->parent()) {
        if (layer == ancestor)
            return true;
    }
    return false;
}

Exemple #3

const LayerChromium* LayerChromium::rootLayer() const
{
    const LayerChromium* layer = this;
    for (LayerChromium* parent = layer->parent(); parent; layer = parent, parent = parent->parent()) { }
    return layer;
}
