different gtkrc 'styles' for different applications

[jos <j g a v riswick tue nl>]

HI

In a gtkrc file one can define a 'mystyle' and then
apply the style to different kinds of widgets
using someting like

widget_class "*.GtkMenuItem.*" style "mystyle"
widget_class "*.GtkCheckButton.*" style "mystyle"

then all widgets that match the given pattern  will
be drawn using the style 'mystyle'. Now I was
wondering if it is also possible somehow, use different
styles for different applications, similar to the way
it can be done in an xresources file. Or maybe it is
possible to attatch a 'style' to all windows with a
certain title or someting like that. 

best regards
