The Qt Core module is part of Qt's essential modules.
The Qt Core module adds these features to C++:
* a very powerful mechanism for seamless object communication called signals and slots
* queryable and designable object properties
* hierarchical and queryable object trees
The following pages provide more information about Qt's core features:
* :ref:`The Meta-Object System<The-Meta-Object-System>`
* :ref:`The Property System<The-Property-System>`
* :ref:`Object Model<Object-Model>`
* :ref:`Object Trees & Ownership<Object-Trees---Ownership>`
* :ref:`Signals & Slots<Signals---Slots>`
Using the Module
^^^^^^^^^^^^^^^^
To include the definitions of modules classes, use the following
directive:
::
import PySide6.QtCore
Threading and Concurrent Programming
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Qt provides thread support in the form of platform-independent
threading classes, a thread-safe way of posting events, and
signal-slot connections across threads. Multithreaded programming is
also a useful paradigm for performing time-consuming operations
without freezing the user interface of an application.
The Thread Support in Qt page contains information on implementing
threads in applications. Additional concurrent classes are provided by
the :ref:`Qt Concurrent<Qt-Concurrent>` module.
Input/Output and Resources
^^^^^^^^^^^^^^^^^^^^^^^^^^
Qt provides a resource system for organizing application files and
assets, a set of containers, and classes for receiving input and
printing output.
* :ref:`Serializing Qt Data Types<Serializing-Qt-Data-Types>`
In addition, Qt Core provides a platform-independent mechanism for
storing binary files in the application's executable.
* :ref:`The Qt Resource System<tutorial_qrcfiles>`
Additional Frameworks
^^^^^^^^^^^^^^^^^^^^^
Qt Core also provides some of Qt's key frameworks.
* :ref:`The Animation Framework<The-Animation-Framework>`
* :ref:`CBOR-Support-in-Qt`
* :ref:`JSON-Support-in-Qt`
* :ref:`Inter-Process-Communication`
* :ref:`The Event System<The-Event-System>`
* :ref:`Application-Permissions`
