Re: Disabling "alt-*" menu functionality




I'm confused by your response: I'm not asking about application development, I'm asking about how to work with or disable gtk's handling of those mnemonics after the fact. It appeared that setting "gtk-enable-mnemonics=0" may have worked for all gtk-2 applications (per the ticket I linked), but it doesn't work now.

If this is the wrong mailing list, please suggest where else I should bring this up. The Ubuntu launchpad ticket I linked appears to be orphaned.

Mnemonics are created, AFAIK, in the code when the menu items are constructed. There are various ways this can be done, but I suspect it cannot be undone if you all you have is a ready to run application.

In GTK2, the simplest way to do this was to put an underscore in front of the desired letter that would act the mnemonic (e.g. "_File" when defining a "File" menu item). There are other ways too, and GTK3 may have changed quite a bit here.

    I didn't write the app. I want to be able to disable the mnemonics globally, and there doesn't appear to be a way to do that in gtk-3.

        Don't create mnemonics when creating menu items. That's all. Our app (Ardour) is GTK (2) but we never define any menu mnemonics, and consequently there are no Alt-* bindings created by GTK (we need all available bindings for the app's own control and management.

            Is there any way to prevent gtk from taking over "alt-*" handling (e.g. alt-f for _File menu, alt-e for _Edit menu) from the application? I can see that some users use that, but others (like me) prefer to rebind alt to other functionality (e.g. find in Firefox).

            Looking into this launchpad ticket [1], it appears that gtk is the root cause here, which is why I'm bringing it up on this list.

            1: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1113420 <https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1113420> <https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1113420 <https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/1113420>>

            There are a handful of suggestions on that ticket, none of which seem to apply to gtk-3. Is there another way to reconfigure gtk in this regard? It seems to be a problem across a variety of window managers (I've seen it in xfce4/xfwm, unity, and lxde/openbox).

            I didn't see any tickets filed about this in the gtk bug tracker, but searching for "alt menu" resulted in a lot f hits...

            Thank you,
