Thank you for the feedback. I think what you are suggesting is a way to
override the default style for a particular widget. I don't think this
achieves my primary goal, though, of avoiding the overhead incurred by
the logic in GTK that supports themes. This overhead includes acquiring
a lock and navigating/manipulating linked lists of styles. Use of a
profiler has shown this to be a significant burden to my application.
What I'm hoping to do is assign widgets a style that I can manipulate
directly and have GTK honor this. gtk_widget_set_style() looks
promising for this, but its associated comment states that "it interacts
badly with themes." GTK changes the style a widget points to under the
sheets, and I don't what events cause it to do so.
I'm not a GTK hacker (probably obvious by now) so I may be going about
this very wrong. I'm hoping someone can point me in the right
direction.
Thanks!
