Trying to learn about GtkUIManager, and running into a strange behavior. As an initial experiment, I'm trying to create a menu bar containing only one menu, which in turn contains only one menu item. This menu bar is the only element in my top-level window. The code (C+ +) is as follows: int main (int argc, char* argv[]) { gtk_init( &argc, &argv ); // Create top-level window and arrange to stop the program when it closes. GtkWidget* window = gtk_window_new( GTK_WINDOW_TOPLEVEL ); g_signal_connect( window, "delete-event", reinterpret_cast<GCallback>(closeMainWindow), NULL ); // Create the UIManager. static const gchar* const menuDef = "<ui>\ <menubar name=\"Menus\">\ <menu name=\"File\" action=\"FileMenuAct\">\ <menuitem name=\"Quit\" action=\"QuitAct\"> </ menuitem>\ </menu>\ </menubar>\ </ui>"; static const GtkActionEntry acts[] = { { "FileMenuAct", NULL, "_File" }, { "QuitAct", GTK_STOCK_QUIT, "_Quit", "<control>Q", "Exit this program", reinterpret_cast<GCallback>(menuShutdown) } }; const guint nActs = 2; GtkActionGroup* menuActions = gtk_action_group_new ( "MenuActions" ); gtk_action_group_add_actions( menuActions, acts, nActs, NULL ); GtkUIManager* menuManager = gtk_ui_manager_new(); gtk_ui_manager_insert_action_group( menuManager, menuActions, 0 ); GError* menuError = 0; const guint mergeID = gtk_ui_manager_add_ui_from_string ( menuManager, menuDef, -1, &menuError ); if ( mergeID == 0 || menuError != 0 ) { cerr << "Error: Failed to add menu definitions to menu UI manager -- " << menuError->message << endl; g_error_free( menuError ); } gtk_ui_manager_ensure_update( menuManager ); GtkWidget* menuBar = gtk_ui_manager_get_widget( menuManager, "/ Menus" ); gtk_container_add( reinterpret_cast<GtkContainer*>(window), menuBar ); // Make everything visible. gtk_widget_show_all( window ); gtk_main(); return 0; } When I run this code, no window appears at all. If I remove the "gtk_container_add" that adds the menu bar to the main window, the program displays an empty window as I would expect it to. I'm using GTk+2 2.6.10 on Mac OS X 10.4.11, running the above program under the X11 that came with the Mac (which identifies itself as X11 1.1.3 - XFree86 4.4.0). Does anyone have any thoughts about what I'm doing wrong? Thanks. _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
