After you build the menu, you can just call show_all_children on the
window that contains it.  This will recursively call show on all
widgets contained in the window.  This saves you from needing to
remember to call show on every single widget.

bool-expression ? expression-if-true : expression-if-false

Is a conditional operator.  Basically its shorthand for:

if( bool-expression )
{
  expression-if-true ;
}
else
{
  expression-if-false ;
}

But you can inline it into function calls and what not.

Its part of C++ and also appears in at least C and Java and probably
others as well. It can be confusing at first, but comes in handy in a
few places.
