Qt4C

Description

This project tries to create a C wrapper library around standard QT widgets so that it can be used as a basis for the development of GUI-based applications using the C programming language.

Requirements

• Qt5 (you may also need to install the package qttools5-dev to get the Qt uitools module working on Linux)
• C++ compiler that supports C++11 features
• CMake >= 3.5

API

The Qt4C api follows the Qt api mostly, which would make it easier to refer to the Qt documentation. As an example:

// ...

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();
    return a.exec();
}

becomes:

#include <wrapper.h>

int main(int argc, char *argv[])
{
    void *a, *w;

    a = qt_application_new(&argc, argv);
    w = qt_widget_new(NULL, 1); /* Indicates that the widget is a window */
    qt_widget_show(w);
    return qt_application_exec(a);
}

Usage

To add Qt4C to your project, you can either clone the source code into your own project tree:

$ git clone https://github.com/iamkhalil/Qt4C.git

or add it as a submodule:

$ git submodule add https://github.com/iamkhalil/Qt4C.git

Then you've to build it:

$ cd Qt4C
$ mkdir build && cd build
$ cmake ..
$ cmake --build .

You can now use Qt4C as a shared library with your C applications. Here is an example CMakeLists.txt file:

cmake_minimum_required(VERSION 3.20)
project(app)

add_subdirectory(Qt4C)
add_executable(myapp main.c)

target_include_directories(myapp PRIVATE Qt4C/src)
target_link_libraries(myapp PRIVATE wrapper)
