[Sablevm-developer] Starting to swing... [screenshots]

[Grzegorz B. P. <ga...@de...>]

Hi all,

I just wanted to share this little happiness with you. The swing code
merged recently from GCJ into GNU Classpath by Michael found its way
into SableVM's "vendor" branch (thanks to Etienne) and I just merged
it on my disk w/ our "staging" version (not yet comitted).

Maybe it's not able yet to run serious Swing apps, but the progress is
very visible. Here you'll find a few screenshots I took while testing
this new version.

Good work, guys!

Can I just say "Wow!"?  That is super cool.  It's fantastic to see
actual Swing screens.

I can add another teaser from the branch. olga rodimina has chased down 
most of the major rendering, geometry, and image transfer bugs in our 
native Graphics2D (cairo) backend. as a result, here is a native swing 
GUI rendering through Graphics2D (note the pervasive smooth vector 
graphics feel):

most of the new widgets there (scroll bars, tab pane) are kim ho's work.

OK SableVM guys!  I'd like to see this in SableVM's staging tree *now*!

To get get SableVM staging to work out-of-the-box with
a Classpath CVS, using:

$ # [go to classpath working copy]
$ cd classpath
$ ./configure --with-vm=sablevm && make && make install

$ # [go to sablevm working copy]
$ cd ../sablevm
$ ./configure && make && make install

$ # [go to swing demo]
$ cd ../swing-demo
$ sablevm SwingDemo

$ # [amazing GUI is now shown :-)]

What's missing?

Two things:

- This code is now only in the development branch of libgcj. To keep the
AWT/Swing hackers busy and to to distracted by all the other cool things
going on this is only merged back to libgcj proper once a month (then it
needs to me merged back to classpath again). Which means that you will
have to wait till 0.09 probably to play with it out of the box.

- Although we have a TestAWT application, we don't have a TestSwing
application. It would be nice if Graydon could post the sources of the
demos he used for the nice shots at http://people.redhat.com/~graydon/
Hint, hint, ... ;)

Cheers,

Mark

OK, this one is fixed now!
http://people.redhat.com/~graydon/testswing.java

And it actually works with GNU Classpath from CVS, hurray!
Although it certainly has some drawing bugs (and you have to click
slightly under the buttons to actually hit them!).
I just checked in one little (compile) fix that I discussed with Graydon
on irc. The rest of the free Swing fixes will come later this month when
we sync again with the libgcj gui-branch.

Other happy news on the GUI front is the release of Odonata 0.1 by
Stephane Meslin-Weber. "Odonata is a set of 100% Java AWT peers for use
with framebuffers. It is  released under the GPL and the ultimate aim is
to provide an alternative replacement for native bindings such as QtAWT,
Gtk or MFC. Replacing AWT peers is a transparent method of extending the
range of platforms and hardware that Java's AWT can be used on."
See for source, screenshots, etc. http://odonata.tangency.co.uk/

Quickly tried it out with jamvm + GNU Classpath cvs and gij (CVS, not
gui-branch) on the VNC backend (it actually includes and runs a VNCj
server!) and there are clearly some drawing/layout problems [lots of
black backgrounds] in our code, but some of the basics work. (For
current GNU Classpath it seems you have to comment out the drawLogo()
call in the uk.co.tangency.odonata.Toolkit constructor - although the
logo shows fine under gij 3.4/CVS.)

Cheers,

Mark
