在上一篇文章中，写了一个helloword来验证GTK+的开发环境是否正常。这一篇，我们一起来详细看一下这个程序的细节。代码如下：

#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 *button;

     window = gtk_application_window_new(app);
     gtk_window_set_title(GTK_WINDOW(window), "Window");
     gtk_window_set_default_size(GTK_WINDOW(window), 480, 360);
     gtk_container_set_border_width(GTK_CONTAINER(window), 28);

     button = gtk_button_new_with_label("Hello World");
     g_signal_connect(button, "clicked", G_CALLBACK(print_hello), NULL);

     gtk_container_add(GTK_CONTAINER(window), button);
     gtk_widget_show_all(window);
}

int main(int argc, char **argv)
{
   
     GtkApplication *app;
     int status;

     app = gtk_application_new("org.gtk.helloword", 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;
}
