Re: CTree expander size

[Henri Torgemane <henrit yahoo-inc com>]

Talking about hacking a custom gtkctree,
it seems gtkclist/ctree are one of the few gtk widgets that are unable to use a
background bitmap given by a style.
I've taken a look at the code, but cannot find how to patch it in a way that
would enable that.

Is it something just hard to do due to the architecture of the widget, or did I
miss the right chunk of code?

Also, is there hope for this in GTK 2?

Thanks,
Henri
