Setting a default control in a windows

[Bob Caryl <bob fis-cal com>]

Hello All,

Gonna try this question again:

I am trying to set a button in my window to be the "default" widget, 
i.e. this buttons "on_clicked" connected function will be executed when 
the enter key is pressed when this window has focus. 

The code I'm using is as follows:

  default_button->set_flags(Gtk::CAN_DEFAULT);
  default_button->grab_default();
  this->activate_default();

and is in the constructor for my window.  This code is called after the 
button in question has been added to the window.

Upon execution and the enter key is pressed, nothing happens.  Any ideas 
on what I'm omitting or doing wrong here?

Thanks,
