pyqt tabs

Tabs are a prominent feature in various graphical applications. These tabbed interfaces can be seen in web browsers, text editors, and numerous other software applications. In order to craft a tabbed interface in your application, PyQt offers the QTabWidget() method. Each individual tab is represented as a QWidget(). Associating these QWidgets to the QTabWidget is achieved through the following method:

tabs.addTab(tab1,"Tab 1")

Here, the initial parameter is the tab’s object, while the second denotes the label that gets displayed to the user. In our example, we’ve embellished the first tab (QWidget) with a few buttons for demonstration.

Detailed Example:

This sample code leverages the qtabwidget to demonstrate the tab display mechanism in PyQt:

from PyQt4 import QtGui
from PyQt4 import QtCore
import sys

def main():

    app = QtGui.QApplication(sys.argv)
    tabs = QtGui.QTabWidget()
  
    # Initializing tabs
    tab1 = QtGui.QWidget()
    tab2 = QtGui.QWidget()
    tab3 = QtGui.QWidget()
    tab4 = QtGui.QWidget()
  
    # Adjusting dimensions
    tabs.resize(250, 150)

    # Designing the first tab's layout
    vBoxlayout = QtGui.QVBoxLayout()
    pushButton1 = QtGui.QPushButton("Start")
    pushButton2 = QtGui.QPushButton("Settings")
    pushButton3 = QtGui.QPushButton("Stop")
    vBoxlayout.addWidget(pushButton1)
    vBoxlayout.addWidget(pushButton2)
    vBoxlayout.addWidget(pushButton3)
    tab1.setLayout(vBoxlayout)
  
    # Integrating tabs
    tabs.addTab(tab1,"Tab 1")
    tabs.addTab(tab2,"Tab 2")
    tabs.addTab(tab3,"Tab 3")
    tabs.addTab(tab4,"Tab 4")
  
    # Assigning a title and making it visible
    tabs.setWindowTitle('PyQt QTabWidget Tutorial at pythonspot.com')
    tabs.show()
  
    sys.exit(app.exec_())

if __name__ == '__main__':
    main()
