问题描述
我正在浏览Qt来源，并注意到此
I was browsing Qt sources, and noticed this
QUuid &operator=(const GUID &guid)
{
*this = QUuid(guid);
return *this;
}
我以前从未见过赋予this
I've never seen assignment to "this" before. What does assignment to "this" do?
推荐答案
这不是 c $ c>但指向 this 指向的对象。这将有效地调用当前对象上的 operator =（QUuid const&）。
That is not an assignment to this but to the object pointed by this. That will effectively call operator=( QUuid const & ) on the current object.
