在QToolbar上隐藏QWidget？

Question

I have directly added some QWidgets to a QToolbar but simply going widget->setVisible(false) did not work. Can someone please give me an example of how to show and hide a widget that is on a QToolbar?

Thanks!

You need to call setVisible() on the appropriate QAction instead. For example, addWidget() returns a QAction*:

QAction* widgetAction = toolBar->addWidget(someWidget);
widgetAction->setVisible(false);
