• gtkmm: C++ Interfaces for GTK and GNOME

• Programming with gtkmm

2. CB20.03+Gtkmm-3.0+MSYS2

• 安装参考网址： https://wiki.gnome.org/Projects/gtkmm/MSWindows
• CB20.03配置和Gtk在CB中的配置过程一样，首先使用pkg-config查寻gtkmm编译依赖相关信息：

# pkg-config --cflags  gtkmm-3.0 |xargs -n1

# pkg-config --libs  gtkmm-3.0 |xargs -n2

然后，在CB中新建一个基于C++语言的项目，并打开项目的Build options...进行以下配置：

1. Other compiler options

2. Linker settings

3. Search directories

3. Hello,Gtkmm

#include <gtkmm.h>

int main(int argc, char** argv)
{
        auto app = Gtk::Application::create(argc, argv);

        Gtk::Window window;
        window.set_title("Hello,Gtkmm..");
        window.set_default_size(400,300);

        return app->run(window);
}

4. 一个带点击事件的简单按钮窗口

#include <gtkmm/window.h>
#include <gtkmm/button.h>
#include <gtkmm/application.h>
#include <iostream>

class Buttons : public Gtk::Window
{
public:
  Buttons();
  virtual ~Buttons();

protected:
  //Signal handlers:
  void on_button_clicked();

  //Child widgets:
  Gtk::Button m_button;
};

Buttons::Buttons()
{
  m_button.add_pixlabel("info.xpm", "cool button");

  set_title("Pixmap'd buttons!");
  set_border_width(10);
  set_default_size(280,40);
  set_position(Gtk::WIN_POS_CENTER);
  m_button.signal_clicked().connect( sigc::mem_fun(*this, &Buttons::on_button_clicked) );

  add(m_button);

  show_all_children();
}

Buttons::~Buttons(){ }

void Buttons::on_button_clicked()
{
  std::cout << "The Button is clicked" << std::endl;
}

int main(int argc, char *argv[])
{
  auto app = Gtk::Application::create(argc, argv, "org.gtkmm.example");

  Buttons buttons;

  //Shows the window and returns when it is closed.
  return app->run(buttons);
}
