With Qt Designer, you can create a dialog's GUI using a built-in template or you can create a dialog entirely from scratch. You can use Qt Designer to create and customize the user interface of your custom dialogs. Qt Designer is a Qt tool that offers a user-friendly GUI that will allow us to quickly create and set up our dialogs and windows. While we can use the QDialog class to build dialogs in Python code, we can also use Qt Designer to create custom dialogs in the drag and drop editor.
QFileDialog for selecting files or directoriesĪdditionally, PyQt provides the QDialog class for creating entirely custom dialogs when there is no built-in available for the operation that you need to perform. QInputDialog for getting a single value from the user. QProgressDialog for providing feedback on the progress of a slow operation. QPrintDialog for specifying the printer's configuration. PyQt offers a rich collection of built-in dialog classes that you can use directly in your applications. They can also be used to ask the users their confirmation to continue with an operation or to take input from the user for a database. Some common examples of dialogs include the Open Document dialog in a word processor or a text editor, the Settings or Preferences dialogs in most GUI applications, the Search dialog in a file manager or a text editor, and so on.ĭialogs are also often used to show error messages or general information on a given operation. In GUI programming, dialogs are small-sized windows that offer auxiliary functionalities and allow you to communicate with your users. With this knowledge, we'll be able to add dialogs to our applications quickly and easily.įor a better understanding of the topics we'll cover in this tutorial, it will help to have some previous knowledge about PyQt applications, widgets, layouts and signals and slots. We'll also learn two different ways of using and launching dialogs in our GUI applications. 
In this tutorial, we'll learn how to create and customize dialogs using Qt Designer. You can use Qt Designer to create dialogs taking advantage of the variety of options that this tool offers. Dialogs are small-sized windows that allow you to communicate with your users, either by showing messages on the screen or by taking the user's input.
Most PyQt GUI applications consist of a main window and several dialogs.
