【GTK3.0】背景设置

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 <gtk/gtk.h> 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; }
