Display a popup when showing a container.

[joaquimduran adtelecom es]

Dear all,

I need to show a custom popup to ask some configuration parameters when a frame
is shown to the user for first time (it's shown inside a notebook).

My idea to implement the behaviour was to overload the on_show member functions of
the frame nad use if to display the popup:

on_show()
{
  Frame::on_Show();
  NewDialog dialog();
  dialog.run();
  [....]
}

Do you know if this behaviour could be a problem for Gtkmm? Is there any other way to
implement it?

Thanks in advance.
