A) Despite claims to the contrary, windows with alpha transparency
is not a feature of X currently; it's also not really a
feature of current versions of Win32 in any general form.
(Longhorn probably will have it.) These are our primary
platforms. The only current GDK target with alpha-transparent
windows is DirectFB, and that's not even integrated into
the GTK+ distribution.
B) Some limited hacks are possible on X, and, I believe, also
on Win32, but emphasize both "limited" and "hacks"
C) Given infinite time, I might try to dust off my fade-in menus
and tooltips hack patch and integrate it properly into GDK, but
my time is very far from infinite these days. I wouldn't be
at all suprised if X *does* have transparent windows before
it hits the top of my TODO pile.
D) Once our primary platforms have support for windows with alpha
transparency, I'm sure we'll support it into GDK.
It's not that translucency isn't considered interesting, but
addressing it in GTK+ when it's not in the windowing system isn't
particularly interesting, or, for that matter, feasible.
