示例1: paint

{
if (m_isWaitingForDidSetFrameNotification) {
WebPageProxy* page = this->page();
if (!page->isValid())
return;
if (page->process()->isLaunching())
return;
}
adjustVisibleRect();
GraphicsContext gc(context);
gc.save();
// Assumes the backing store is painted with the scale transform applied.
// Since tile content is already scaled, first revert the scaling from the painter.
gc.scale(FloatSize(1 / m_contentsScale, 1 / m_contentsScale));
IntRect dirtyRect = mapFromContents(rect);
TiledDrawingAreaTile::Coordinate topLeft = tileCoordinateForPoint(dirtyRect.topLeft());
