CopperSpice

Introduction

CopperSpice is a set of individual libraries which can be used to develop cross platform software applications in C++. It is a totally open source project released under the LGPL V2.1 license and was initially derived from the Qt framework. Over the last several years CopperSpice has completely diverged, with a goal of providing a first class GUI library to unite the C++ community.

Our motivation for developing CopperSpice was to change the fundamental design and turn the existing framework into a set of libraries for C++ developers. We are accomplishing this by leveraging modern C++ functionality, new technology, and modern tooling. CopperSpice currently requires C++17 or newer.

The libraries avaiable in CopperSpice include:

• CsCore
• CsGui
• CsMultimedia
• CsNetwork
• CsOpenGL
• CsScript
• CsSql
• CsSvg
• CsWebKit
• CsXml
• CsXmlPatterns

There are also several open source BSD licensed libraries which are used by CopperSpice and available as stand alone libraries for anyone developing C++ applications.

• CsPrint
• CsSignal
• CsString
• CsLibGuarded

System Requirements

To use the CopperSpice libraries a C++17 compiler and a C++17 standard library are required.

CopperSpice CMake build files are provided with the source distribution. We recommend your projects should also use CMake for the build system.

For additional information about building from source, refer to our CopperSpice Overview Documentation or the KitchenSink demo application for sample CMake project files.

Building

The CopperSpice libraries are built using the CMake build system.

Documentation

Overview

The CopperSpice Overview documentation includes information on building CopperSpice, downloading prebuilt binary files, package requirements, setting up an application which links with CopperSpice, migrating to CopperSpice, and general configuration information.

API

The API contains full class documentation and multiple tutorials for CopperSpice and is available directly on our website and from our download page.

Major Enhancements

Reflection

• No Meta-Object Compiler is required for generating meta data, all references were removed
• The functionality provided by moc was replaced with compile time templates
• CopperSpice automatically generates meta data for processing Signals/ Slots and Introspection
• A template class can now inherit from QObject with no restrictions on types
• Complex data types such as QMap<QString, int> can be used for signal or slot arguments

Enhanced Functionality

• CopperSpice makes extensive use of modern C++ features

  • constexpr, variadic templates, SFINAE, lambda expressions, tuple, move semantics, and type traits

• Redesigned all container classes to use the C++ standard library containers, iterators, and algorithms

• CopperSpice includes a majority of the Qt 5 classes

• New platform independent plugin system based on C++

• High DPI Support

• Integration of CsSignal

  • Improved thread aware Signal/Slot delivery
  • Increased efficiency while maintaining the full Signal/Slot API
  • Deadlocks in Signal/Slot processing have been eliminated

• Integration of CsString

  • Improved storage to properly represent Unicode strings
  • QString8 (UTF-8) and QString16 (UTF-16) classes
  • Added QStringView and QStringParser

• Integration of CsLibGuarded

  • Used to manage shared data

Using the Libraries

• Any C++ application using CopperSpice can be built with CMake or any build system which imports CMake files
• CopperSpice can be linked directly into any standard C++ application
