C++ (Cpp) GraphicsContext::clearRect Beispiele

Beispiel #1

void LayerTreeCoordinator::paintContents(const WebCore::GraphicsLayer* graphicsLayer, WebCore::GraphicsContext& graphicsContext, WebCore::GraphicsLayerPaintingPhase, const WebCore::IntRect& clipRect)
{
    if (graphicsLayer == m_nonCompositedContentLayer) {
        m_webPage->drawRect(graphicsContext, clipRect);
        return;
    }

    if (graphicsLayer == m_pageOverlayLayer) {
        // Overlays contain transparent contents and won't clear the context as part of their rendering, so we do it here.
        graphicsContext.clearRect(clipRect);
        m_webPage->drawPageOverlay(graphicsContext, clipRect);
        return;
    }
