Nowhere. GTK+ 3.x does not have drawing area anymore.

To use a Pango font with Cairo, you should:
1. create a Pango_Layout on the given context (Create_Layout);
2. set Pango font there (Set_Font_Description);
3. set text to render into the layout (Set_Text);
4. draw the layout (Show_Layout_Line).
For further information see:
https://developer.gnome.org/pango/unstable/pango-Cairo-Rendering.html
Examples of use with GtkAda are here (require some adjustments for GTK
3.x).

Since Pango fonts and Toy fonts are considerably different in their use,
the library has an abstraction layer in order to be able to use both.
