无法隐藏QMenu对象QMenu :: setVisible()? [英] Not possible to hide a QMenu object QMenu::setVisible()?

问题描述

我在应用程序中的MainWindow顶部建立了QMenu MainMenu.大家都习惯了，我有以下QMenu主菜单:

I have built up a QMenu MainMenu on top of my MainWindow in my application. As everybody is used to it, I have following QMenu Main menus:

文件-编辑-SuperHeavyExpertMenus-设置-帮助

File - Edit - SuperHeavyExpertMenus - Settings - Help

我想在程序启动时最初隐藏子树SuperHeaverExpertMenus，因为它包含很多设置，这可能会使初学者感到困惑.

I would like to hide the sub tree SuperHeaverExpertMenus initially, on program start, because it conatins a lot of settings, which might confuse beginner users.

例如，当设置"中的复选框为true时，我想用SuperHeavyExpertMenu显示该子树.

I want to show that sub tree with SuperHeavyExpertMenu, when a checkbox in Settings is true, for instance.

我可以隐藏上述QMenu的子级QActions，竞争QAction:setVisible(false).但我可以针对QMenu吗?

I can hide the children QActions of the QMenu s above, vie QAction:setVisible(false) . but I can do that for the QMenu ?

是否可以隐藏QMenu?
