其实在不同平台上的应用程序，其常用控件往往都是类似的。

比如按钮控件、布局方式等等，在Android、ios、Windows、Linux上都是相近的，方法也类似。这次的笔记涉及到GTK3中对控件的一种布局方式：Packing。

其效果如下：

该窗口使用Packing，实现了三个按钮控件的布局。代码如下：

#include <gtk/gtk.h>static void print_hello (GtkWidget *widget, gpointer   data){    g_print ("Hello World\n");}int main (int  argc, char *argv[]){    GtkWidget *window, *grid, *button;    gtk_init (&argc, &argv);    /*创造一个新窗口window，并且设置标题等*/     window = gtk_window_new (GTK_WINDOW_TOPLEVEL);    gtk_window_set_title (GTK_WINDOW (window), "Grid");    g_signal_connect (window, "destroy", G_CALLBACK (gtk_main_quit), NULL);    gtk_container_set_border_width (GTK_CONTAINER (window), 10);    /*现在我们构建一个 pack 我们按钮的 container*/    grid = gtk_grid_new ();    /* 将这个container pack 在我们的窗口window中*/    gtk_container_add (GTK_CONTAINER (window), grid);    button = gtk_button_new_with_label ("Button 1");    g_signal_connect (button, "clicked", G_CALLBACK (print_hello), NULL);    /*将button放置在距左端0,距上边0的位置,设置宽为1，高为1.*/    gtk_grid_attach (GTK_GRID (grid), button, 0, 0, 1, 1);    /* 函数声明     void  gtk_grid_attach  (GtkGrid  *grid, GtkWidget *child,                            gint left,  gint top,  gint width,  gint height);    */    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 (button, "clicked", G_CALLBACK (gtk_main_quit), NULL);    gtk_grid_attach (GTK_GRID (grid), button, 0, 1, 2, 1);    gtk_widget_show_all (window);    gtk_main ();    return 0;}

先写到这儿。
