GTK 3.0弹出窗口及设置背景图片的代码

代码如下：

#include <gtk/gtk.h>

int main(int argc,char *argv[])
{
    gtk_init(NULL, NULL);

    GtkWidget* window=gtk_window_new(GTK_WINDOW_TOPLEVEL);

    //设置大小，弹出位置，图标，等等
    gtk_signal_connect(G_OBJECT(window),"destroy", G_CALLBACK(gtk_main_quit),NULL);

    GtkWidget* image=gtk_image_new_from_file("your pictrue");
    gtk_container_add(GTK_CONTAINER(window), image);
    gtk_widget_show_all(window);

    gtk_main();

    return 0;
}
