How to duplicate a widget

["Diego A. Fons" <diegofons apexar com>]

Hi,

I have to duplicate some widgets which i've extended from the ones in GTKmm:

class GraphicalButton : public Gtk::Button

I am making copies of these widgets using the traditional "copy 
constructor way" like this:

GrahicalButton* oneButton = new GraphicalButton();
GrahicalButton* anotherButton = new GraphicalButton( *oneButton );

Is this OK? What's the correct way of making a copy of one widget?

Best regards,
Diego A. Fons.
