Re: Toy menu program (GtkItemFactory) *gives no errors* but menu doesn't appear!? How debug?

Thanks! I'm so glad you sent this reply!
I changed gtk_widget_show to gtk_widget_show_all
like you said and now my menus appear!!!

Do you know why the menubar would take over
the whole window? The 2 menu items "File" and "Help"
are huge.  It looks like one must specify size
of menu bar somewhere. :(

(I saw one example program that defined a vbox
and one that avoided that..... perhaps one needs
a vbox or something like that?! errrr. :)

Thanks again,

Chris

P.S. Here is code with your suggested change...

#include <gtk/gtk.h>

static void printHelloWorld(GtkWidget *w, gpointer data) {
  g_message("HelloWorld!\n");
};

static GtkItemFactoryEntry theMenu[] = {
  {"/_File",            NULL, NULL,            0, "<Branch>"},
  {"/File/_New",        NULL, printHelloWorld, 0, "<Item>"},
  {"/File/<Separator>", NULL, NULL,            0, "<Separator>"},
  {"/File/_Quit",       NULL, gtk_main_quit,   0, "<Item>"},
  {"/_Help",            NULL, NULL,            0, "<LastBranch>"},
  {"/Help/_See Docs",   NULL, NULL,            0, "<Item>"},
  {"/Help/_About",      NULL, NULL,            0, "<Item>"},
};

int main(int argc, char** argv) {
  GtkWidget*      window;
  GtkItemFactory* item_factory;
  GtkAccelGroup*  accel;
  
  gtk_init(&argc, &argv);

  /* Basic window creation stuff here. */
  window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  gtk_window_set_title(GTK_WINDOW(window), "Window Title Here");
  gtk_window_set_default_size(GTK_WINDOW(window), 200, 200);

  /* Here is menu stuff. */
  accel = gtk_accel_group_new();
  item_factory = gtk_item_factory_new(GTK_TYPE_MENU_BAR, "<main>", accel);
  gtk_item_factory_create_items(item_factory, sizeof(theMenu) / sizeof(theMenu[0]), theMenu, NULL);
  gtk_accel_group_attach(accel, GTK_OBJECT(window));
  gtk_container_add(GTK_CONTAINER(window), gtk_item_factory_get_widget(item_factory, "<main>"));
  
  /* Basic ending stuff here. */
  gtk_widget_show_all(window);
  gtk_main();
  return 0;
};
