示例1: convertFromContainingWindow
FloatPoint Widget::convertFromContainingWindow(const FloatPoint& windowPoint) const
{
// Widgets / windows are required to be IntPoint aligned, but we may need to convert
// FloatPoint values within them (eg. for event co-ordinates).
IntPoint flooredPoint = flooredIntPoint(windowPoint);
FloatPoint parentPoint = this->convertFromContainingWindow(flooredPoint);
FloatSize windowFraction = windowPoint - flooredPoint;
// Use linear interpolation handle any fractional value (eg. for iframes subject to a transform
// beyond just a simple translation).
// FIXME: Add FloatPoint variants of all co-ordinate space conversion APIs.
if (!windowFraction.isEmpty()) {
const int kFactor = 1000;
IntPoint parentLineEnd = this->convertFromContainingWindow(flooredPoint + roundedIntSize(windowFraction.scaledBy(kFactor)));
FloatSize parentFraction = (parentLineEnd - parentPoint).scaledBy(1.0f / kFactor);
parentPoint.move(parentFraction);
}
return parentPoint;
