示例1: paintContents
void SelectionOverlay::paintContents(const GraphicsLayer* layer, GraphicsContext& c, GraphicsLayerPaintingPhase, const IntRect& inClip)
{
if (!layer->platformLayer()->superlayer())
return;
Selection::iterator it = m_selection.find(layer->platformLayer()->superlayer()->owner());
if (it == m_selection.end())
return;
const Vector<WebCore::FloatQuad>& quads = it->value;
GraphicsLayer* parent = it->key;
IntRect clip(inClip);
clip.move(parent->offsetFromRenderer().width(), parent->offsetFromRenderer().height());
c.save();
c.translate(-parent->offsetFromRenderer().width(), -parent->offsetFromRenderer().height());
Color color = RenderTheme::defaultTheme()->activeSelectionBackgroundColor();
c.setFillColor(color, ColorSpaceDeviceRGB);
for (unsigned i = 0; i < quads.size(); ++i) {
FloatRect rectToPaint = quads[i].boundingBox();
// Selection on non-composited sub-frames need to be adjusted.
if (!m_page->focusedOrMainFrame()->contentRenderer()->isComposited()) {
WebCore::IntPoint framePosition = m_page->frameOffset(m_page->focusedOrMainFrame());
