Question

此代码不会返回编译错误...通过启动应用程序，打开窗口但不显示菜单栏...我在哪里错了？有人可以告诉我为什么？我没有找到解决方案的问题！：（

#include "header.h"

int main(int argc, char **argv)
{
  GtkWidget *window;
  GtkWidget *vbox;

  GtkWidget *menubar;
  GtkWidget *fileMenu;
  GtkWidget *fileMi;
  GtkWidget *quitMi;

  gtk_init(&argc, &argv);

  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
  gtk_window_set_default_size(GTK_WINDOW(window), 300, 200);
  gtk_window_set_title(GTK_WINDOW(window), "Simple menu");

  vbox = gtk_box_new(GTK_ORIENTATION_VERTICAL, 0);
  gtk_container_add(GTK_CONTAINER(window), vbox);

  menubar = gtk_menu_bar_new();
  fileMenu = gtk_menu_new();

  fileMi = gtk_menu_item_new_with_label("File");
  quitMi = gtk_menu_item_new_with_label("Quit");

  gtk_menu_item_set_submenu(GTK_MENU_ITEM(fileMi), fileMenu);
  gtk_menu_shell_append(GTK_MENU_SHELL(fileMenu), quitMi);
  gtk_menu_shell_append(GTK_MENU_SHELL(menubar), fileMi);
  gtk_box_pack_start(GTK_BOX(vbox), menubar, FALSE, FALSE, 0);

  //gtk_widget_show(fileMi);

  g_signal_connect(G_OBJECT(window), "destroy",
                   G_CALLBACK(gtk_main_quit), NULL);

  g_signal_connect(G_OBJECT(quitMi), "activate",
                   G_CALLBACK(gtk_main_quit), NULL);

  gtk_widget_show_all(window);

  gtk_main();

  return 0;
}

我正在使用：GTK + 3

Gtk没有显示窗口中的菜单栏
