Hi Tim,
does the MSVC port library support the windowing system of Windows?
And yet, what happened to the proposal of using the Apache Portable
Runtime as an interface to the native layer?

There is a wxWindows cross platform C++ library but it has a very big
abstraction layer overhead on top of platform APIs. Also there is GTK+ which
has a win32 port and some linux native applications like gimp and xchat have
win32 native ports to windows. QT is also free for non profit usage, but
only for non-profit.
I see what you are saying: all windowing native issues are managed by

I am not a UI person as well but as far as I know you are right. Porting
layers for UI are huge and not trivial, and there is nothing about UI in the
port library.

I see what you are saying: all windowing native issues are managed by
SWT or AWT, therefore the port library dosen't include and windowing
native functions. Right?

Well we can't run apps that require AWT or Swing at the moment, but we
can run GUI apps (like Eclipse and RSSOwl) that are SWT-based.
Of course, the plan is for Harmony to have AWT and Swing code.

SWT is available under the EPL. I was only teasing though, it is not a
solution for our need to write the JSE windowing libraries.

AFAIK you generally choose a windowing manager and code to it -- I'm
unaware of any cross-manager port libraries (but I'm not a UI person so
there may well be such a thing).

I don't get exactly how and in which terms we can use the SWT
(cross-platform GUI develiped by IBM)....
Does instead, the port library for UNIX support any windows manager?

I believe it remains a proposal. Artem Aliev did some work on using APR
as a portability layer (by coding the Harmony portlib to APR) in late
February, and reported his findings to the list[1]. AFAIK nobody has
continued this work.
