Re: Crashing with widgets as class members

[Bob Caryl <bob fis-cal com>]

My class containing widgets is created with "new" long after the start
of the program, after other classes using gtkmm have functioned
correctly (and Gtk::Main) has been called.

Am I doing something illegal when I do:

class MyClass {
   public:
   Gtk::ComboBoxText mycombo_;
}

Hey John,

As you can see above, you are NOT creating Gtk::ComboBoxText as a 
pointer.  You are instantiating it in your MyClass definition.  This 
means that instantiation is going to happen before you initialize the 
toolkit.
