Hi,

the title says it all. The method is usable, but I don’t find it in the  
sources…

Who can enlighten me? Are there some kind of docs, where this magic is  
explained?

Cheers, detlef

It is automatically defined. Ruby/GLib defines acceessors  
for properties  
automatically. Gtk::MessageDialog.set\_secondary\_text is a  
getter for secondary-text property:  
[Gtk – 3.0](https://developer.gnome.org/gtk3/stable/GtkMessageDialog.html#GtkMessageDialog--secondary-text)

## Thanks,
