	Ho hum; so I read the bug, and I read the code - and I removed  bogus
class, and a superstitious mis-understanding of the visibility
annotation. Having said that - unwinding exactly what is intended to be
exposed there is really hard.

	Are there good docs ? what is this tree view control supposed to do ?
can we insert bitmap items into it ?

	Right - not ideal :-)

	Right - it does this because in

class UnoTreeListItem : public SvLBoxItem

	is not in fact an LBOXSTRING. Quite probably it should be - after all
we have some text.

	So - as/when you can compile - I would suggest switching the code to
derive from SvLBoxString, and binning 'maText' in favour of
SvLBoxString's 'aStr' - and also junking the 'IsA' impl. - which should
then make things work for you :-)

	Yep - unfortunately the code then starts casting it to a 'SvLBoxString'
- which (might) work much of the time due to similar class layout ;-)
but is not a real fix.

	Any chance you could look into that ? and/or where are you stuck with
building ?

	Thanks !
