我如何在 gtkmm3 中动态命名小部件变量？

Question

我正在尝试创建 10 个 Gtk::Buttons 而不是

Gtk::Button *button1 = new Gtk::Button;
Gtk::Button *button2 = new Gtk::Button;
Gtk::Button *button3 = new Gtk::Button;
...
Gtk::Button *button10 = new Gtk::Button;

grid.add(*button1); grid.add(*button2); grid.add(*button3); //...

A Qt but similar question is here

我试过 Qt example，但它有文件名，我不知道它是为了什么。

对于字符串数组（有"button1","button2","button3"的列表）循环会在这里产生指针错误

grid.add(*button1)
         ^_______

我需要做的是为按钮的变量生成动态命名，然后执行

grid.add(*button1);
grid.add(*button2);
grid.add(*button3);
...
grid.add(*button4);

为了弄清楚我的问题，我最终从不同的人那里挑选了信息并将其组合成以下内容

main.cpp

#include <gtkmm.h>
#include <map>
#include <string>

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

  Gtk::Window window;Gtk::Grid grid;
  window.set_default_size(600, 600);
  std::string name = "button";
  std::map<std::string, Gtk::Button*> all_buttons;
  for (int i = 1; i <= 10; i++)
  {
    Gtk::Button *button = new Gtk::Button("Button " + std::to_string(i));
    all_buttons[name] = button;
    grid.add(*button);
  }
  window.add(grid);
  window.show_all_children();

  return app->run(window);
}
