Title: fonts in gtkmm1.2

I found a sloution for changing the font in Gtkmm 1.2 Widgets:

Gtk::Style *s = label.get_style();
Gdk_Font f = gdk_font_load("-*-helvetica-bold- …..")
s.set_font(f);

the only disatwantage of this code ist that it changes the font for all Widgets in the window. Does anybody know a solution which changes the font only in that widget which should be changed?
