---------- This is a resubmission of my original message to roottalk without
embedded figures.
For some reason, a mail with embedded figures (bitmaps or jpegs) doesnt get
accepted by the
rootalk server. The embeded figs were only 24kb and 48kb. I have seen bigger
attachments than that on roottalk....

Dear Valery,
I send this also to roottalk so other people can see (and appreciate) the
great progress you made!
After our phone conversation I experimented more and this is the status so
far:
The bad news first:
I never got your Qt distribution to work on my NT4/SP6 box. I removed ALL
other root installations
and checked the registry for any root-dll references (which were none). I
rebooted, reinstalled YOUR
Qt-root version and still get the bomb with null pointer exeption when I try
to run any of the demos
or the
TF1 foo("foo","sin(x)/x",-10,10);
foo.Draw();
example.
However, I can bring up the Browser and the Inspector ( e.g. with
foo.Inspect() ) and miraculously
those work fine (with the nice new sort feature). More amazingly, in the
Browser I can go to the root memory
folder where the TF1 foo object is (when I created it before on the cmd line
without trying to Draw() it),
and when I double click it the c1 canvas with the correct image draws
perfectly fine with menus and all!
That is very strange. It works when I draw through the browser but NOT from
the cmd line! That means that
the correct Qt libs must be there otherwise TBrowser,TInspector and TCanvas,
TF1 wouldn't be able to draw
anything ....
I have to say that I have still Qt3.01 installed on that machine (and
hesitate to uninstall it since
the installer recompiles the whole distribution and that takes 1-2hrs on
that 500MHz machine...). Also
the 'nonQt' option (set QTDIR=) works just fine without any crashes. So the
problem must be in
the Qt part...
Better news next:
Thane told me that on HIS machine (running Win2k, Qt3.00 installed and a
root v3.02.06 aside
of your root-Qt distribution) things worked much better.
He was able to run MOST (but not all) of the demos as well as that TF1 foo
example above.
But he had crashes when he tried to Save As... a canvas, or Copy to
clipboard did not work either.
So on his machine it worked much better but not as perfect as on your
development machine.
Best news last:
Now I also installed your Qt-root on my home machine (Win2k, Qt2.3-free
installed and root v3.01.05 aside your
Qt-root) and there things run "almost perfect" (probably just the same as on
your development box):
I can run ALL demos,
print directly to the printer (without .ps and ghostscript steps)
save as jpeg etc..
copy to clipboard and into MSWord and from word into Outlook express
(below).
Also TBrowser, TInspector etc work fine (and much prettier than the old
windows versions!).
THIS IS FANTASTIC!!
After how many years (?) of dealing with eps files and ghostscript on
windows we FINALLY have a copy/paste
graphics solution, nicer browsers etc...!!
I do NOT understand the reasons why we have different results on different
machines. You said you linked
Qt libs statically so the other Qt dll's on the same machine should never be
referenced (and how could it run
perfectly on my home machine with the old Qt2.3 libs which are definitely
incompatible with Qt3.0x)
On my home machine I noticed a few glitches so far:
In my TF1 foo example above, the zoom on the x-axis works fine, but
strangely NOT on the y-axis!
In the hsimple demo and most TH1 drawings we have one or several vertical
lines in the middle of
the histogram: (the figure below was just copied/pasted to/from clipboard -
no fiddling around with ps tools any more!!!):
--- Fig showing the demo-simple histogram with one vertical line near zero
that shouldn't be there (fig removed)
In the graph demo the Ytitle does not rotate:
--- Fig showing the demo-graph plot with y-axis label horizontal instead of
vertical (fig removed)
I could play with the GraphicsEditor and most things work as expected. Had
some difficulties with
the polyline drawing. When I tried to delete the polyline object with the
rightclickmenu->Delete
the TOption dialog box came up and froze the machine (even CTRL-Alt-Del
didn't work - was forced to
a reboot). That doesn't happen often with win2k (haven't had system freeze
crashes in several weeks if not months!).
In any case, the "working" version on my home Win2k machine is HUGE progress
in the root-windows world.
I am convinced that THIS is the right approach to the root-windows future.
I(we) just have to figure out
what the problem is with the other machines/configurations. Maybe we wait
till your souce is available so we
can look at the crashes in the debugger ....
Thanks so much, Valery!
This is very very much appreciated...
All the best
peter (Lipa)
