let QTabWidget show the corresponding page when mouse cursor hover on the tab

I want to show the corresponding page when mouse cursor hover on the tab of a QTabWidget.

For example ,when the mouse cursor hover on tab ‘page2’ here , I hope the QTabWidget show the corresponding page automatically instead of clicking,so how to implement this feature ?

Hi,

Just a quick idea: subclass QTabBar and react to the QHoverEvent then subclass QTabWidget to use your custom QTabBar

Hope it helps

I implement in this way

    def mouseHoverOnTabBar(self):
        self.tabBar=self.tabWidget.tabBar()
        self.tabBar.setMouseTracking(True)
        self.tabBar.installEventFilter(self)

    def eventFilter(self, obj, event):
        if obj == self.tabBar:
            if event.type() == QEvent.MouseMove:
                index=self.tabBar.tabAt(event.pos())
                self.tabBar.setCurrentIndex (index)
                return True
        return super().eventFilter(obj, event)

Right, didn't thought of the eventFilter... Good one !
