GTK+3开发

GTK+3可以运行在WIN下和LINUX下。

#include 
  
   


int main( int argc, char *argv[])
{
  GtkWidget *window;
  GtkWidget *fixed;
  GtkWidget *button;

  gtk_init(&argc, &argv);

  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  gtk_window_set_title(GTK_WINDOW(window), 你好);
  gtk_window_set_default_size(GTK_WINDOW(window), 230, 150);
  gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);

  fixed = gtk_fixed_new();
  gtk_container_add(GTK_CONTAINER(window), fixed);

  button = gtk_button_new_with_label(退出);

  gtk_fixed_put(GTK_FIXED(fixed), button, 50, 50);
  gtk_widget_set_size_request(button, 80, 35);

  g_signal_connect(G_OBJECT(button), clicked,
      G_CALLBACK(gtk_main_quit), G_OBJECT(window));

  g_signal_connect_swapped(G_OBJECT(window), destroy,
      G_CALLBACK(gtk_main_quit), NULL);

  gtk_widget_show_all(window);

  gtk_main();

  return 0;
}
