methods missing from ruby bindings when using smoke built with the new generator

[Stefano Crocco-2]

After succeeding in building smoke with the new generator, I found out two
problems running my programs using the ruby bindings.

The first problem is that the KDE::SharedConfig doesn't seem to have a #group
method anymore. Looking at the KDE api, that method is defined in the
KConfigBase, from which KDE::SharedConfig is derived, so I think it should be
availlable. You can see this error running the following code.

require 'korundum4'

data = KDE::AboutData.new "test", "", KDE::ki18n("Test"), "0.0.0"

KDE::CmdLineArgs.init ARGV, data

a = KDE::Application.new
c = KDE::Global.config
c.group 'xyz'

The last line causes the error:

in `method_missing': undefined method `group' for
#<KDE::SharedConfig:0x825caa0> (NoMethodError)

The second problem is that Qt::SizePolicy#setHorizontalStretch doesn't seem to
work. According to rbqtapi, a binding for the
QSizePolicy::setHorizontalStretch exists, but in practice it doesn't work.
This can be seen in any file generated by rbuic, such as that contained in the
calculatorform qtruby example. Running it, it gives:

ui_calculatorform.rb:32:in `method_missing': undefined method
`setHorizontalStretch' for #<Qt::SizePolicy:0x8404d04 horizontalPolicy=5,
verticalPolicy=5> (NoMethodError)

I don't know whehter this is an issue with the new smoke generator or not. The
fact is that if I replace the new version of smoke with an old one, build
using kalyptus (revision 1000944) everything start working again. So, I think
that either the new generator or some other change in smoke since that
revision should be blamed for these issues (of course, provided I'm not doing
something wrong).

Maybe this is a known issue, but I chose to report it just in case it wasn't.

Thanks in advance

Stefano

I wrote this message more than two weeks ago and I didn't get any answers. I
can think of three reasons for this:
1) the developers don't have time to answer right now
2) my mail went unnoticed
3) the problems I describe only exist on my system

In the first case, there's nothing to say: I'll wait until the developers have
more free time and go on using the old version of smoke which is working quite
well. By the way, I'd like to thank the developers for all the work they're
doing to produce such wonderful software.

If my mail was unnoticed, I hope that this will bring it to the attention of
the developers.

If nobody else can reproduce the errors I described, please tell me so. This
way, I'll know that there's something wrong with my system and start
investigating about it.

I generally don't like writing mails like this, pressing people to answer my
questions. The only reason I'm doing it now is to make sure the developers
know of a serious (at least, unless it only happens to me) issue. In
particular, I find the problem with Qt::SizePolicy very serious because makes
the Qt designer completely useless, as the code for all the widgets it creates
contains calls to Qt::SizePolicy#setHorizontalStretch which crash the program.

Sorry for the noise

Thanks in advance for any help and for the understanding

Stefano

My apologies, I'm really behind with sorting out bugs in QtRuby/Korundum. I've
been really busy with a stressful day job, and also working on the QtScript
smoke binding, and just hadn't had any time for Ruby. There are quite a few
things I want to improve in QtRuby after working on the QtScript binding, as
well as fix these outstanding bugs for the KDE 4.4 release.

No problem at all, thanks for taking the time to report the bugs. I'll try and
investigate the problems as soon as I can.

Sorry. I really didn't notice your mail. I was quite busy with school, fixing
other bugs in smokegenerator and starting a new project to auto-generate the
C# sources.

No need to apologize. If we aren't responding within two weeks I guess it's
justified to send us an additional note :). Especially when we seem to be
active otherwise ;).

To the problem itself: I just grepped for setHorizontalStretch in
smokedata.cpp and got this:
    "setHorizontalStretch",     //13047
    "setHorizontalStretch$",    //13048
    {392, 13047, 1003, 1, 0, 0, 18},    //15152
QSizePolicy::setHorizontalStretch(unsigned char)
    {392, 13048, 15152},        // QSizePolicy::setHorizontalStretch$
So the method signature name is munged correctly and the method entry itself
is also there. But a quick test with irb fails for me as well. Maybe QtRuby
wants to look up the full method signature and is confused by "unsigned char"
!= "uchar" != "char" ? Maybe it tests for any of these types.
