Gnome /GTK menu bar creation

[bluedalmatian]

Ive got a gnome app called mainwindow which is declared like this:

GtkWidget* mainwindow = gnome_app_new("Name","Name");

This window loads up fine and has been part of a working application for a few weeks. Im now trying to add a menubar accross the top which will contain one menu (Help) with one item (About). The code Im using is as follows:

GtkWidget* menubar;
GtkWidget* helpitem;
GtkWidget* helpmenu;
GtkWidget* aboutitem;


menubar=gtk_menu_bar_new();
helpitem=gtk_menu_item_new_with_label("Help");
aboutitem=gtk_menu_item_new_with_label("About");
helpmenu=gtk_menu_new();
gtk_menu_item_set_submenu(GTK_MENU_ITEM(helpitem), helpmenu);
gtk_menu_shell_append(GTK_MENU_SHELL(helpmenu),abo utitem);
gtk_menu_shell_append(GTK_MENU_SHELL(menubar),help item);
gnome_app_set_menus(GNOME_APP(mainwindow),GTK_MENU _BAR(menubar));
gtk_widget_show_all(menubar);

This compiles fine and the app runs but the menu bar doesnt show up.

Can anybody see what Ive done wrong as as far as I can see it matches the examples Ive looked at?

Thanks

Could you post the complete source code of the application? Also, please enclose the posted code in code tags so that it would be easier to read.

Ive fixed it.

strange thing it appears the two arguments to

mainwindow = gnome_app_new("Name","Name");

MUST be the same. In my app they werent. It was only when I copied and pasted the relevent bits of code out into a tiny dummy app that I could post here that I realised.

so thanks for the suggestion :)
