请问QLabel的linkActivated(const QString&) 和linkHover信号在什么时候发送阿?文档是这样说的:
linkActivated:This signal is emitted when the user clicks a link. The URL referred to by the anchor is passed in link.
linkHover:This signal is emitted when the user hovers over a link. The URL referred to by the anchor is passed in link.
怎样在Qlabel上面创建一个link呢?
