Gtkmm

Because gtkmm is the official C++ interface of the GUI library GTK, C++ programmers can use the common OOP techniques such as inheritance, and C++-specific facilities such as STL (In fact, many of the gtkmm interfaces, especially those for widget containers, are designed to be similar to the Standard Template Library (STL)).

Main features of gtkmm are listed as follows:

• Use inheritance to derive custom widgets.
• Type-safe signal handlers, in standard C++.
• Polymorphism.
• Use of Standard C++ Library, including strings, containers, and iterators.
• Full internationalization with UTF-8.
• Complete C++ memory management.
• Object composition.
• Automatic de-allocation of dynamically allocated widgets.
• Full use of C++ namespaces.
• No macros.
• Cross-platform: Linux (gcc, LLVM), FreeBSD (gcc, LLVM), NetBSD (gcc), Solaris (gcc, Forte), Win32 (gcc, MSVC++), macOS (gcc), others.

//HelloWorldWindow.h

1. ifndef HELLOWORLDWINDOW_H
2. define HELLOWORLDWINDOW_H

1. include
2. include

// Derive a new window widget from an existing one.

// This window will only contain a button labelled "Hello World"

class HelloWorldWindow : public Gtk::Window

{

public:

HelloWorldWindow();

protected:

Gtk::Button hello_world;

};

1. endif

//HelloWorldWindow.cc

1. include
2. include "HelloWorldWindow.h"

HelloWorldWindow::HelloWorldWindow() : hello_world("Hello World")

{

// Set the title of the window.

set_title("Hello World");

// Add the member button to the window.

set_child(hello_world);

// Handle the 'clicked' signal.

hello_world.signal_clicked().connect([] () {

std::cout << "Hello world" << std::endl;

});

}

//main.cc

1. include
2. include "HelloWorldWindow.h"

int main(int argc, char *argv[])

{

// Create an application object.

auto app = Gtk::Application::create("org.gtkmm.example");

// Create a hello world window object and return when it is closed.

return app->make_window_and_run(argc, argv);

}

The above program will create a window with a button labeled "Hello World". The button sends "Hello world" to standard output when clicked.

The program is run using the following commands:

$ g++ -std=c++17 *.cc -o example `pkg-config gtkmm-4.0 --cflags --libs`

$ ./example

This is usually done using a simple makefile.
