Hey,

I do have a panel over Firefox's main window. The panel has a
transparent background. unfortunately you can now click through the
panel on the UI elements below it (when clicking on white-space), or
if the panel is above a text field, the cursor will change.

This is obviously by design and probably makes sense in many
situations, but doesn't make sense in others. Is there a W3C-
definition that "transparent" means like "air" and not like "glass"
concerning the focus?

Is there a way to make a transparent panel, that won't lose focus when
clicking on white-space?

Thanks a lot!
Cheers.

p.s. same goes for rgba(x,x,x,0).

There's been a proposal to expand the SVG pointer-events property
to apply to HTML. WebKit has implemented this already. I've created
a wiki page for it here, hopefully the details will wind up in a
spec reasonably soon.

In XUL there might be other ways to do this.. but I'm not familiar
with XUL at all.

You're probably thinking of the "mousethrough" attribute which roc had
to reimplement as part of his display lists so he'd know exactly how it
works.

Jonathan Watt is implementing this as we speak.
