Re: [PHP-GTK] GtkStyle this time....

OK, I do have a follow on question though...and maybe this is due to my
poor understanding of GTK+ at this point. Are all the widgets supposed to
share the same GtkStyle object?

The reason I ask is that in building the GUI if I change the style
structure of one of the three main widgets (a Ctree, Clist and a
GtkText) all three seem to inherit the changes. However if I get the
GtkStyle object, copy it, change it and then change the widgets style
object to the new Style then it of course only effects that one.

I only ask becuase I can't seem to find a decent answer in the GTK+
docs/mailing lists etc.

thanks,
