创建应用程序时，您需要在窗口中放置多个窗口小部件。当您要将多个窗口小部件放入窗口时，控制每个窗口小部件的位置和大小变得非常重要。
GTK +带有各种各样的布局容器，其目的是控制添加到其中的子窗口小部件的布局。

#include <gtk/gtk.h>static void print_hello (GtkWidget *widget,             gpointer   data){  g_print ("Hello World\n");}static void activate (GtkApplication *app,                      gpointer  user_data){  GtkWidget *window;  GtkWidget *grid;  GtkWidget *button;  /* 创建一个新的window，并设置他的title */  window = gtk_application_window_new (app);  gtk_window_set_title (GTK_WINDOW (window), "Window");  gtk_container_set_border_width (GTK_CONTAINER (window), 10);  /* 构建一个容器来放置我们的button */  grid = gtk_grid_new ();  /* 把容器放入窗口中 */  gtk_container_add (GTK_CONTAINER (window), grid);  button = gtk_button_new_with_label ("Button 1");  /* 链接button的clicked（点击）事件  g_signal_connect (button, "clicked", G_CALLBACK (print_hello), NULL);  /*    * gtk_grid_attach参数（GtkGrid *parent,GtkWidget child,gint left,gint top,gint width,gint heigjt）   */  gtk_grid_attach (GTK_GRID (grid), button, 0, 0, 1, 1);  button = gtk_button_new_with_label ("Button 2");  g_signal_connect (button, "clicked", G_CALLBACK (print_hello), NULL);  gtk_grid_attach (GTK_GRID (grid), button, 1, 0, 1, 1);  button = gtk_button_new_with_label ("Quit");  g_signal_connect_swapped (button, "clicked", G_CALLBACK (gtk_widget_destroy), window);  gtk_grid_attach (GTK_GRID (grid), button, 0, 1, 2, 1);//这里我们做完了所有的事 显示布局  gtk_widget_show_all (window);}int main (int    argc,          char **argv){  GtkApplication *app;  int status;  app = gtk_application_new ("org.gtk.example", G_APPLICATION_FLAGS_NONE);  g_signal_connect (app, "activate", G_CALLBACK (activate), NULL);  status = g_application_run (G_APPLICATION (app), argc, argv);  g_object_unref (app);  return status;}
