QAction自带的tooltip怎么隐藏？

Question

试过了让setToolTip里面为空字符，但是不管用，请问有什么方法让tooltip不弹出提示吗？

引用来自“精英王子”的答案

In order to show a tooltip on a QAction in a QMenuBar, one has to overload the event() method on the QMenuBar and look for an event of type QEvent::Tooltip. When it arrives, one can ask QMenuBar::activeAction() to know over which QAction the mouse pointer is, and then finally call QToolTip::showText on that QAction's tooltip.

可能需要继承QAction类，重写event方法，过滤QEvent::Tooltip事件，用来自QToolTip的底层函数来关掉tooltip

这个方法很复杂啊，也许有更简单的方法
