A module which provides a set of C++ technologies for building user interfaces The QtWidgets module provides a set of UI elements to create classic desktop-style user interfaces. Widgets ^^^^^^^ Widgets are the primary elements for creating user interfaces in Qt. They can display data and status information, receive user input, and provide a container for other widgets that should be grouped together. A widget that is not embedded in a parent widget is called a window. .. image:: images/parent-child-widgets.png The :class:`QWidget` class provides the basic capability to render to the screen, and to handle user input events. All UI elements that Qt provides are either subclasses of :class:`QWidget` , or are used in connection with a :class:`QWidget` subclass. Creating custom widgets is done by subclassing :class:`QWidget` or a suitable subclass and reimplementing the virtual event handlers. * :ref:`Window and Dialog Widgets` * :ref:`Application Main Window` * :ref:`Dialog Windows` * :ref:`Keyboard Focus in Widgets` Styles ^^^^^^ :ref:`Styles` draw on behalf of widgets and encapsulate the look and feel of a GUI. Qt's built-in widgets use the :class:`QStyle` class to perform nearly all of their drawing, ensuring that they look exactly like the equivalent native widgets. :ref:`Qt Style Sheets` are a powerful mechanism that allows you to customize the appearance of widgets, in addition to what is already possible by subclassing :class:`QStyle` . Layouts ^^^^^^^ :ref:`Layouts` are an elegant and flexible way to automatically arrange child widgets within their container. Each widget reports its size requirements to the layout through the :meth:`sizeHint` and :meth:`sizePolicy` properties, and the layout distributes the available space accordingly. :ref:`Qt Widgets Designer` is a powerful tool for interactively creating and arranging widgets in layouts. Model/View Classes ^^^^^^^^^^^^^^^^^^ The :ref:`model/view` architecture provides classes that manage the way data is presented to the user. Data-driven applications which use lists and tables are structured to separate the data and view using models, views, and delegates. .. image:: images/fusion-treeview.png Graphics View ^^^^^^^^^^^^^ The :ref:`Graphics View Framework` is for managing and interacting with a large number of custom-made 2D graphical items, and a view widget for visualizing the items, with support for zooming and rotation. .. image:: images/graphicsview-items.png Using the Module ^^^^^^^^^^^^^^^^ To include the definitions of modules classes, use the following directive: :: import PySide6.QtWidgets
