Radio button has a circular shape and used when one choice is to be selected from multiple options. This button is in the selected state when the circle is filled and deselected when the circle is hollow. QRadioButton class is used to add a radio button in an application.
Example:
A window asking the user to select user’s gender. According to the user’s choice, it shows a message: “You are male/female” and which will change if the user changes his/her selection.
Below is the code:
Python3
import sysfrom PyQt5 import QtCore, QtGui, QtWidgetsclass Ui_MainWindow(object): def setupUi(self, MainWindow): MainWindow.setObjectName("MainWindow") MainWindow.resize(466, 299) self.centralwidget = QtWidgets.QWidget(MainWindow) # Radio button for male self.radioButton_male = QtWidgets.QRadioButton(self.centralwidget) self.radioButton_male.setGeometry(QtCore.QRect(180, 120, 95, 20)) # adding signal and slot self.radioButton_male.toggled.connect(self.maleselected) # Radio button for female self.radioButton_female = QtWidgets.QRadioButton(self.centralwidget) self.radioButton_female.setGeometry(QtCore.QRect(180, 150, 95, 20)) # adding signal and slot self.radioButton_female.toggled.connect(self.femaleselected) self.label = QtWidgets.QLabel(self.centralwidget) self.label.setGeometry(QtCore.QRect(170, 90, 211, 20)) MainWindow.setCentralWidget(self.centralwidget) self.retranslateUi(MainWindow) QtCore.QMetaObject.connectSlotsByName(MainWindow) def maleselected(self, selected): if selected: self.label.setText("You are male") def femaleselected(self, selected): if selected: self.label.setText("You are female") def retranslateUi(self, MainWindow): _translate = QtCore.QCoreApplication.translate MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow")) self.radioButton_male.setText(_translate("MainWindow", "Male")) self.label.setText(_translate("MainWindow", "Select your gender:")) self.radioButton_female.setText(_translate("MainWindow", "Female"))# Driver Codeif __name__ == "__main__": app = QtWidgets.QApplication(sys.argv) MainWindow = QtWidgets.QMainWindow() ui = Ui_MainWindow() ui.setupUi(MainWindow) MainWindow.show() sys.exit(app.exec_()) |
Output:
According to user’s choice a message will appear “You are male” or “You are female” and which will change as user changes his/her selection.
