Top-Level Windows

A top-level window is created using the following piece of code:

 /* this variable will store a pointer to the window object. */
 GtkWidget* main_window;

 /* create a new top-level window. */
 main_window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

 /* define some of the window's attributes. */
 gtk_window_set_default_size(GTK_WINDOW(main_window), 500, 300);
 gtk_window_set_title(GTK_WINDOW (main_window),
                      "A Top Window For The Rest Of Us...");
 gtk_container_set_border_width(GTK_CONTAINER (main_window), 5);

 /* make the window visible. */
 gtk_widget_show(main_window);

Note: the actual redrawing of the window will be done only when control gets to GTK's main loop.
