Detailed use of QTabWidget

Introduction to QTabWidget

QTabWidget is mainly used for paging display, each page has an interface, and many interfaces share a common area, which saves the interface size and displays more information for users conveniently.

1. Create four QWidgets

        self.tab1 = QWidget()
        self.tab2 = QWidget()
        self.tab3 = QWidget()
        self.tab4 = QWidget()

2. Add four QWidgets to the tab

        self.addTab(self.tab1, "Tab 1")
        self.addTab(self.tab2, "Tab 2")
        self.addTab(self.tab3, "Tab 3")
        self.addTab(self.tab4, "Tab 4")

3. Make an interface for each tab respectively

        self.tab1UI()
        self.tab2UI()
        self.tab3UI()
        self.tab4UI()

4. Complete source code
