I designed a basic GUI with Menu bar and menu items in glade. I use the glade bindings in haskell to get the menu item using xmlGetWidget and castToMenuItem function. I set a *onActivateItem* handler for this menuitem. However this is not working.

You're not the only one confused, I've never really understood the profusion of actions on Gtk+ menu items, but onActivateLeaf seems to be the one to use.

I saw the glade file and it has a signal function in the xml. I tried to use the same function name, but it doesn't work either.

Ignore that, it only works for C code.

Any suggestions on what I might be doing wrong here and how to get menu item handlers working.

There are three places to look at for help, the demos, the API documentation and the gtk2hs-users mailing list. The demos: ---------- Take a look at the menu demo that comes with gtk2hs (in the gtk2hs tarball under demo/menu/MenuDemo.hs). You'll notice it uses onActivateLeaf rather than onActivateItem. The API docs: ------------- http://haskell.org/gtk2hs/docs/current/Graphics-UI-Gtk-MenuComboToolbar-Menu... (linked from http://haskell.org/gtk2hs/documentation/) say: onActivateItem :: MenuItemClass self => self -> IO () -> IO (ConnectId self) Emitted when the user chooses a menu item that has a submenu. This signal is not emitted if the menu item does not have a submenu. onActivateLeaf :: MenuItemClass self => self -> IO () -> IO (ConnectId self) The user has chosen the menu item. This is the only function applications normally connect to. It is not emitted if the item has a submenu. The mailing list: ----------------- http://haskell.org/gtk2hs/development/#mailing_lists Duncan
