Library to manage menus in embedded device for C/C++

Question

I'm looking for a library to manage menus. I'm looking for something which is based on configuration files. It doesn't have to manage keyboard input or display, just the menu logic. What I have in mind something like:

//menu.xml
<menu>
    <Start />
    <Stop />
    <Configuration displayname="Configure System">
        <Sound type="toggle" />
        <Speed display="Speed related settings">
           <Speedy type="toggle" default="on" />
           <Optimizations type="toggle" />
        </Speed>
    </Configuration>
    <Filesystem>
         <SaveSnapshot />
         <LoadSnapshot />
    </Filesystem>
</menu>

In the code we would have:

//menu.cpp
Menu menu("menu.xml");
menu.bind("SaveSnapshot",saveSnapshotPressed);
menu.bind("LoadSnapshot",loadSnapshotPressed);
menu.bind("Sound",soundSetTo);
...
void onKeyPressed(key_t key) {
...
    switch (key) {
    case KEY_UP:
        menu.goUp();
        break;
    case KEY_DOWN:
        menu.goDown();
        break;
    case KEY_ENTER:
        menu.action();
        break;
    }
// display.cpp
void render(...) {
    for (int i=0;i<menu.items().size();++i) {
        renderText(getMenuCoord(i),menu.items()[i].c_str());
    }
    ...
}

Such a library could be very useful to display menus in embedded device.

I'll be glad to hear if such library exists, or is there a better idea for this library.

There are things like Kaleido: http://www.digitalairways.com/kaleido-engine.htm which are very nice, but pricey.

Emwin is simpler and cheaper but nothing like as rich in terms of functionality: http://www.segger.com/cms/emwin.html

You may want to look at the Android SDK. This too, may be more than you want to handle, but there may be value in replicating, or possibly using any tools google may have.
