Just a sketch:


BigWidget : public PG_Widget
{
    ....
    private:
        bool eventKeyDown(SDL_KeyboardEvent* key);
    ....
        PG_ListBox *listbox1, *listbox2;
}


bool BigWidget::eventKeyDown(SDL_KeyboardEvent* key)
{
    switch (key->keysym.sym)
    {
        case SDLK_DOWN:
            listbox1->SelectNextItem();
            fillListBox2();
            break;
        case SDLK_LEFT:
            listbox2->SelectPrevItem();
            break;
        case SDLK_RETURN:
            executeAction();
            break;
        ....
    }

    return true;
}


This should work. If nothing happens because the BigWidget doesn't get
the events, set a capture hook (see pgmessageobject.h). Then it gets ALL
events that are generated.

Any open questions?
