Subject: [freeqt] New harmony snapshot (1999.09.01)


	There is a new harmony snapshot available from
ftp://ftp.yggdrasil.com/pub/dist/GUI/harmony/devel/snapshots/harmony-1999.09.01.tar.gz.

	It has the following changes:

		o Harmony now compiles with the 1999.08.24 snapshot
		  of egcs/gcc.  This may be important because egcs-1.1.2
		  would print rather disconcerting apparently incorrect
		  warnings that "statement has no effect" when pixmaps
	          were being copied in some of the painting related
		  code (qpainter.h, I think), and this would suggest
		  serious misconceptions going on inside of the
		  compiler.  gcc 2.95 and 2.95.1 get internal compiler
		  errors from one of the header files (qwidget.h, I think).
		  As it stands, this latest egcs/gcc snapshot also
		  fails to build if it is given both "-O" and "-g"
		  compiler options, but Mark Mitchell emailed me
		  to tell me that he has a handle on this problem
		  and expects to check the fix into the egcs/gcc
		  development tree in the next few days.

		o Bug fixes: One of the pixmap constructor functions
		  attempted to call another one as a subroutine to do
		  some of the initialization when, in fact, it was just
		  creating and destroying a whole new pixmap.  I
		  have fixed this, although in a rather duplicative
		  way, which ought to get cleaned up at some
		  point.  Elsewhere, a test for a subroutine variable
		  being null was inverted, causing segmentation faults.
		  That is fixed now.

		o There is an initial implementation of setTimer,
		  killTimer and killTimers in qobject.{h,cc} now,
		  although it only has one second resolution.

	This snapshot includes Harry Morgan's work on moving toward
Qt-2.x support and the Platinum theme, although I believe that was
in the previous snapshot.

	I have a request for people checking code into Harmony: for
the time being, please put your name or email address in your
cvs commit comments.  Somehow, the commits are all being recorded
as being done by "anoncvs", and I have not figured out if I can
easily tweak the commit logging to record the cvs user name instead
of the system user name.

	I have been slowly working through the examples in the
Qt tutorial, as some initial test cases on which to develop
Harmony.  Harmony now can run up to example 9 with no code
modifications (other than adjusting the build process to use magna).
Example 10 runs with a one line modification to flush the queue on
a QPainter object to work around a Harmony bug where the reference
counting on pixmaps is somehow broken and a pixmap is being
deallocated before a write from it is performed.  Examples 11 and 12
compile and link (now that the timer functions are implemented),
but have a bug which I think is the same as was worked around in example
10.  Any assistance with this bug would be greatly appreciated.
Example 13 needs a very simple method missing from QLCDNumber
(intValue(void)) to link.  The final example, number 14, needs
a missing include file (perhaps a missing class): qaccel.h.

	Once the tutorial examples all work, then I think the
next step would be to start trying to make some of the simpler
Qt applications compile.
