由于GTK 3.0将许多GTK 2.0的API都丢弃，转到GTK 3.0下编译后有些不适应，所以感觉能在GTK 3.0下调试成功这个Demo还是很成功的。

源码

#include 
    
        int main( int argc, char *argv[])   {               GtkWidget *window;               GtkWidget *layout;               GtkWidget *image;               GtkWidget *button;               gtk_init(&argc, &argv);               window = gtk_window_new(GTK_WINDOW_TOPLEVEL);               gtk_window_set_default_size(GTK_WINDOW(window), 290, 200);               gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);               layout = gtk_layout_new(NULL, NULL);               gtk_container_add(GTK_CONTAINER (window), layout);               gtk_widget_show(layout);               image = gtk_image_new_from_file("bg.jpg");               gtk_layout_put(GTK_LAYOUT(layout), image, 0, 0);               button = gtk_button_new_with_label("Button");               gtk_layout_put(GTK_LAYOUT(layout), button, 20, 50);               gtk_widget_set_size_request(button, 80, 35);               g_signal_connect_swapped(G_OBJECT(window), "destroy",G_CALLBACK(gtk_main_quit), NULL);               gtk_widget_show_all(window);               gtk_main();               return 0;}
