How to create a modal window in pyqt?

I looked into the documentation and I found self.setWindowModality(QtCore.Qt.WindowModal).

I added this function to my __init__ function, but however still was not able to create a modal dialog box.

Any help will be appreciated,
Thank You.

You should use the setWindowModal(2) method from your QWidget object

from PyQt5 import QtGui, QtWidgets, QtCore
from PyQt5.QtWidgets import QApplication, QWidget, QMainWindow
import sys

class MainWindow(QMainWindow):
    def __init__(self):
        super(MainWindow, self).__init__()
        self.setGeometry(400, 400, 500, 500)
        self.setWindowTitle("Multi Window Application")
        self.initUI()
    def initUI(self):
        self.child_access = QtWidgets.QPushButton(self)
        self.child_access.setText("Child 1")
        self.child_access.adjustSize()
        self.child_access.move(100, 100)
        self.child_access.clicked.connect(self.openChild1)
    def openChild1(self):
        self.child1 = Child1()
        self.child1.setWindowModality(2)
        self.child1.show()

class Child1(QWidget):
    def __init__(self):
        super().__init__()
        self.setGeometry(200, 200, 300, 300)
        self.setWindowTitle("Child 1")
        self.initUI()
    def initUI(self):
        self.label = QtWidgets.QLabel(self)
        self.label.setText("Child1")

if __name__ == "__main__":
    app = QApplication(sys.argv)
    win = MainWindow()
    win.show()
    app.exec_()
    sys.exit()

QDialog has setModal() as found here.

As the docs state:

By default, this property is False and show() pops up the dialog as modeless. Setting this property to true is equivalent to setting QWidget.windowModality to Qt.ApplicationModal.

As @sebastian noted you could use exec(). However it is better to use exec_() as the one sebastian mentioned is also a python call.

Example:

my_dialog = QDialog(self) 
my_dialog.exec_()  # blocks all other windows until this window is closed.

If this doesn't help please post your code and I will have a look.
