Re: GdkRectangle, again

["Ross McFarland" <rwmcfa1 neces com>]

it's nice to be able to set the members without having to call a function.you
would like to be able to $update_rect->{x} = 5; granted it's just as easy to
say $update_rect->x(5); but that's not what you'd first assume would be the
case. these are c structures that in a c app you directly manipulate. when in
perl that equates to a hash. and that would probably be people's first
assumption to what a GtkRectangle would/should be.

there's nothing keeping you from making it functions that operate on a hash so
that you could choose which way. use it as hash ($rect->{x}) or as a function
($rect->x)
