PyQt QTabWidget

While using the GUI program, you can see a window with a Tab as shown above.

These tabs can be useful because the components in the program do not take up a large area and can be categorized according to categories.

In a simple example, let's create a widget with two tabs.

QTabWidget

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QTabWidget, QVBoxLayout

class MyApp(QWidget):

    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        tab1 = QWidget()
        tab2 = QWidget()

        tabs = QTabWidget()
        tabs.addTab(tab1, 'Tab1')
        tabs.addTab(tab2, 'Tab2')

        vbox = QVBoxLayout()
        vbox.addWidget(tabs)

        self.setLayout(vbox)

        self.setWindowTitle('QTabWidget')
        self.setGeometry(300, 300, 300, 200)
        self.show()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = MyApp()
    sys.exit(app.exec_())

A small widget with two tabs is created.

Description

tab1 = QWidget()
tab2 = QWidget()

You have created two widgets to be placed on each tab.

tabs = QTabWidget()
tabs.addTab(tab1, 'Tab1')
tabs.addTab(tab2, 'Tab2')

Use QTabWidget() to create tabs, and add Tab1 and Tab2 to tabs using addTab().

vbox = QVBoxLayout()
vbox.addWidget(tabs)

self.setLayout(vbox)

Create one vertical box layout and put tabs.

Then set the vertical vbox to the widget's layout.
