About Lesson

In this PyQt5 MessageBox lesson, we want to learn about Working with QMessageBox in PyQt, so the the QMessageBox class provides a modal dialog for informing the user or for asking the user a question and receiving an answer. there are different types of pyqt messagebox that you can us, for example we have about messagebox,information messagebox, warning messagebox and multichoice messagebox.

 

This is the complete code for Working with QMessageBox in PyQt

 

 

These are our window requirements like window title, window icon, width and height of the window, x and y position of the window.

 

 

We want to add our widgets in the HBoxlayout.

 

 

These are our four buttons and we have already connected the clicked signal of these buttons with the slots or methods that we want to create.

 

 

When you create layouts and widgets in your pyqt applications, you need to add all your widgets in the layout.

 

 

Also you need to set layout for the main window, if you don’t do this you will not see any widgets in the window.

 

 

You can create pyqt5 messagebox by creating the object of QMessageBox class. so you can see that we have created four types of QMessageBox.

 

 

For every pyqt application you need to create the object of QApplication, and the argument is optional.

 

 

 

Run the complete code and this is the result.
