PyQt5 - QFormLayout Class

QFormLayout is a convenient way to create two column form, where each row consists of an input field associated with a label. As a convention, the left column contains the label and the right column contains an input field. Mainly three overloads of addRow() method addLayout() are commonly used.

Example

This code adds a LineEdit field to input name in the first row. Then it adds a vertical box layout for two address fields in the second column of the next row. Next, a horizontal box layout object containing two Radio button fields is added in the second column of the third row. The fourth row shows two buttons ‘Submit’ and ‘Cancel’.

def window():
   app = QApplication(sys.argv)
   win = QWidget()

   l1 = QLabel("Name")
   nm = QLineEdit()

   l2 = QLabel("Address")
   add1 = QLineEdit()
   add2 = QLineEdit()
   fbox = QFormLayout()
   fbox.addRow(l1,nm)
   vbox = QVBoxLayout()

   vbox.addWidget(add1)
   vbox.addWidget(add2)
   fbox.addRow(l2,vbox)
   hbox = QHBoxLayout()

   r1 = QRadioButton("Male")
   r2 = QRadioButton("Female")
   hbox.addWidget(r1)
   hbox.addWidget(r2)
   hbox.addStretch()
   fbox.addRow(QLabel("sex"),hbox)
   fbox.addRow(QPushButton("Submit"),QPushButton("Cancel"))

   win.setLayout(fbox)
   
   win.setWindowTitle("PyQt")
   win.show()
   sys.exit(app.exec_())

if __name__ == '__main__':
   window()

The above code produces the following output −
