您如何将GLArea与gtkmm一起使用？

如何解决您如何将GLArea与gtkmm一起使用？

我不知道您应该如何在gtkmm中使用GLArea； gtkmm演示中的示例已过时，并使用了不再存在的功能。我想我需要自己提供OpenGL函数，所以我为此使用了GLFW（因为我对此有经验）。这是到目前为止的整个程序：

#include <gtkmm.h>
#include <giomm/resource.h>
#include <GLFW/glfw3.h>

class TestWindow : public Gtk::Window {
protected:
  Gtk::GLArea mGlArea;
  
  void onRealize() {
    mGlArea.make_current();
    if (!glfwInit())
      exit(EXIT_FAILURE);
    glClearColor(0.0f,0.0f,1.0f,1.0f);
  }

  void onUnrealize() {
  }

  bool onRender(const Glib::RefPtr<Gdk::GLContext>& context) {
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    return false;
  }
public:
  virtual ~TestWindow(){};
  TestWindow(){
    set_title("Window Title");
    add(mGlArea);
    mGlArea.set_auto_render();
    mGlArea.set_hexpand();
    mGlArea.set_vexpand();
    mGlArea.set_halign(Gtk::ALIGN_FILL);
    mGlArea.set_valign(Gtk::ALIGN_FILL);
    mGlArea.set_size_request(640,360);
    mGlArea.set_required_version(3,3);
    mGlArea.signal_realize().connect(sigc::mem_fun(this,&TestWindow::onRealize));
    mGlArea.signal_unrealize().connect(sigc::mem_fun(this,&TestWindow::onUnrealize),false);
    mGlArea.signal_render().connect(sigc::mem_fun(this,&TestWindow::onRender));
    mGlArea.show();
  }
};

int main(int argc,char* argv[]) {
  Glib::RefPtr<Gtk::Application> app = Gtk::Application::create(argc,argv,"org.gtkmm.examples.base");
  TestWindow mainWindow;
  return app->run(mainWindow);
}

它可以编译，但是运行时遇到分段错误，这是gdb的回溯信息：

我正在使用Linux，并且之前在此精确设置上使用过GLFW，所以我认为问题不在于缺少OpenGL支持或类似的问题。如果我省略行mGlArea.show();，我将不会再遇到细分错误，但是显然这不是很有帮助。 GTK根本不是这种事情的正确选择吗（这是我第一次使用GTK）？这是一个工程项目，最终结果需要一个3D渲染的窗口，几个实时图形，并且就此完成。
