[PATCH] kconfig qconf: port to QT4

[PATCH] kconfig qconf: port to QT4

[Alexander Stein]

A straight forward port to QT4 using qt3to4 and compiling against
  qt3support

* rewritten makefile rules to use qmake based qt setup which is hopefully
  portable enough
* ConfigInfoView::menu has to be renamed as QT4 moc strips struct from
  struct menu and creates a name conflict

I've only very little experience with Qt 3 or 4. The patch basically
changes most QSomeClass to Q3SomeClass, which is the Qt3-compatible
wrapper around QSomeClass. Now is it possible to still support Qt3? E.g.
have a header file that #defines Q3SomeClass back to QSomeClass and does
similar with the Qt headers, would that be possible? I know that Qt4 has
be there for five years already, but if the cost of keeping support for
old userspace is not too hight, I would try it.

BTW, after applying your patch, make xconfig starts ok, but clicking in
the main menu does nothing, and if I close the close button, it does not
exit, but stops reacting to any input (but it still handles window
resize). The qt3 version would display the "Save changes?" dialog here.

I never thought about qt3 compatibility but It seems to me that renaming the 
qt3 compat classes and revert the header file name changes should suffice to 
compile against qt3 again. But then somebody else has to do the makefile magic 
to support both versions. Also which version should be prefered if both are 
available?

I can click in the window around and closing the window using the X button 
asks me about saving the changes. Which QT version do you use actually?

Best regards
Alexander

Re-enabling kconfig for gt4 only distros like mdv, would be hugely 
appreciated Alexander.  I have never been comfy with menuconfig, which is 
forced now.

So thanks for anything you can do about making both gconfig and kconfig 
work, as neither does on mdv-2010-x86-64.

I'd say the Qt4 version, leaving the qt3 for those who have no other
option (and then letting it bitrot once the last user installs Qt4 :-)).

Strange, now it works fine. I'll play with it a bit more and then I'll
tell you for sure.

[PATCH v2] kconfig qconf: port to QT4

[Alexander Stein]

A straight forward port to QT4 using qt3to4 and compiling against
  qt3support

* rewritten makefile rules to detect QT4 by using qmake which is hopefully
  portable enough
* If no QT4, QT3 will by tried instead
* Classes renamed using qt3to4
  * If build using QT3 renamed to QT3 class names using defines
* ConfigInfoView::menu has to be renamed as QT4 moc strips struct from
  struct menu and creates a name conflict

Signed-off-by: Alexander Stein <alexander.stein@informatik.tu-chemnitz.de>
---
Changes in v2:
* Use QT3 as fallback if no QT4 is available
* Rename class names using defines for QT3

Hi Alexander,

first, one thing I forgot to mention: There are some changes by Li Zefan
in my kconfig branch, which conflict with your patch. I resolved the
conflicts myself (but see below), but could you please use the kconfig
or for-next branch of
git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild-2.6.git next
time? If you already have a clone of Linus's tree, then just do

$ git remote add kbuild \
  git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild-2.6.git
$ git remote update kbuild
$ git checkout -b kconfig kbuild/kconfig

This will only download a few hundred kilobytes.

Unfortunatelly, this doesn't work for me if I uninstall libqt4-devel and
use qt3-devel, because then I have:
$ qmake --version
Qmake version: 1.07a (Qt 3.3.8b)
Qmake is free software from Trolltech ASA.
$ which qmake
/usr/lib/qt3/bin/qmake

I'm using openSUSE 11.3, but I think this is a generic problem, qmake
existed before QT4.

Here, you are removing compatibility code for pre-3.0.0 QT versions.
That's perfectly fine in 2010 :-), but could you also please mention it
in the changelog and remove the other occurences of this ifdef in qconf.cc?

Other than that, I haven't found other issues with *your* patch, but
when I merge it with 39a4897 (xconfig: add support to show hidden
options which have prompts) and work around the above Makefile issue, I get

QObject::connect: No such signal QActionGroup::selected(Q3Action*)
QObject::connect:  (sender name:   'unnamed')
QObject::connect:  (receiver name: 'config')
QObject::connect: No such signal QActionGroup::selected(Q3Action*)
QObject::connect:  (sender name:   'unnamed')
QObject::connect:  (receiver name: 'menu')

and the Option -> Show Normal/All/Promp options menu added by 39a4897
does not work. The problem is that the QT4 moc does not run the
preprocessor, so the Q3Action token is not replaced by QAction. The QT4
does not have this limitation anymore, so I was wondering: Instead of
renaming every single class name in the source and then defining the
names back for QT3, could we just define the classes to the Q3Foo
versions for the QT4 case? This would solve the issue with the QT3 moc
and also make the patch smaller.

For reference, here is the resulting patch I used:

Subject: [PATCH] kconfig qconf: port to QT4

A straight forward port to QT4 using qt3to4 and compiling against
  qt3support

* rewritten makefile rules to detect QT4 by using qmake which is hopefully
  portable enough
* If no QT4, QT3 will by tried instead
* Classes renamed using qt3to4
  * If build using QT3 renamed to QT3 class names using defines
* ConfigInfoView::menu has to be renamed as QT4 moc strips struct from
  struct menu and creates a name conflict

For reference, here is the resulting patch I used:

From 99913f21e95a4da1b58a50321564c10ca567d498 Mon Sep 17 00:00:00 2001
From: Alexander Stein <alexander.stein@informatik.tu-chemnitz.de>
Date: Tue, 13 Jul 2010 21:26:56 +0200
Subject: [PATCH] kconfig qconf: port to QT4

A straight forward port to QT4 using qt3to4 and compiling against
  qt3support

* rewritten makefile rules to detect QT4 by using qmake which is hopefully
  portable enough
* If no QT4, QT3 will by tried instead
* Classes renamed using qt3to4
  * If build using QT3 renamed to QT3 class names using defines
* ConfigInfoView::menu has to be renamed as QT4 moc strips struct from
  struct menu and creates a name conflict

[PATCHi v3] kconfig qconf: port to QT4

[Alexander Stein]

A straight forward port to QT4 using qt3to4 and compiling against
  qt3support

* rewritten makefile rules to detect QT4 by using qmake which is hopefully
  portable enough
* If no QT4, QT3 will by tried instead
* Classes renamed using qt3to4
  * If build using QT3 renamed to QT3 class names using defines
* ConfigInfoView::menu has to be renamed as QT4 moc strips struct from
  struct menu and creates a name conflict
* QT2 support has been dropped
* The hidden options inserted in 39a4897c1bb66e8a36043c105d7fd73d8b32b480
  are use in native API

Signed-off-by: Alexander Stein <alexander.stein@informatik.tu-chemnitz.de>
---
Changes in v2:
* Use QT3 as fallback if no QT4 is available
* Rename class names using defines for QT3

Changes in v3:
* based on git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild-2.6.git
  kconfig branch
* Proper support for hidden options from 39a4897c1bb
* slightly rework Makefile detection to use pkg-config for QT4 detection
* Removed USE_QT3 usage, use QT_VERSION instead
* Drop QT2 support

Michael,

i kept using Q3Foo classes and redefine them to QFoo instead of the other way
around, as defining QFoo to Q3Foo doesn't work here.

[PATCH] kconfig qconf: port to QT4

[Alexander Stein]

A straight forward port to QT4 using qt3to4 and compiling against
  qt3support

* rewritten makefile rules to detect QT4 by using qmake which is hopefully
  portable enough
* If no QT4, QT3 will by tried instead
* Classes renamed using qt3to4
  * If build using QT3 renamed to QT3 class names using defines
* ConfigInfoView::menu has to be renamed as QT4 moc strips struct from
  struct menu and creates a name conflict

This patch is pretty the same as in 1280488517-30116-1-git-send-email-alexander.stein@informatik.tu-chemnitz.de.
But this is based on v2.6.35-rc6, hence hidden option feature is missin.

Looks like this did not make it into .36...  would you have a version that works with .36-rc

It is in the kconfig branch of
git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild-2.6.git and
will end up in 2.6.37-rc1.

[PATCH 1/2] kconfig qconf: port to QT4

[Alexander Stein]

A straight forward port to QT4 using qt3to4 and compiling against
  qt3support

* Use pkg-config to detect QT4 which is hopefully portable enough
* If no QT4, QT3 will by tried instead
* Classes renamed using qt3to4
  * If build using QT3 renamed to QT3 class names using defines
* ConfigInfoView::menu has to be renamed as QT4 moc strips struct from
  struct menu and creates a name conflict
* QT2 support has been dropped
* The hidden options inserted in 39a4897c1bb66e8a36043c105d7fd73d8b32b480
  are use in native API

[PATCH 2/2] Fix QT4 moc, cflags libs detection on dual QT3/Qt4 systems

[Alexander Stein]

On system with QT3 and QT4 qmake in PATH may be from QT3. So we use
pkg-config for proper QT4 detection.
By reqesting cflags and libs for either QtCore, QtGui and QtSupport include
dirs and libs get listed several times, but so we won't mis anything

OK.

A couple of issues here: 1) The script is running under set -e, so if
there is no Qt4, it will exit right away. 2) The '$?' is interpreted by
make, you need to say '$$?' if you want the shell see '$?'. Last but not
least, there is no C-style arithmetics in the [ builtin, [ ! 0 ] and [ !
1 ] will both evaluate to failure. You probably meant [ $$? -ne 0 ], but
it still wouldn't work because of 1). Just use

  if ! pkg-config --exists QtCore 2> /dev/null; then
    ... qt 3 ...
  else
    ... qt 4 ...
  fi

When I fix it manually, it works OK both under Qt4 and Qt3, which is
great, but please submit a patch that you tested yourself. If you're
quick (but not too quick to omit testing), I'll push it in this merge
window.

thanks,
Michal

[PATCH v4] kconfig qconf: port to QT4

[Alexander Stein]

A straight forward port to QT4 using qt3to4 and compiling against
  qt3support

* Use pkg-config to detect QT4 which is hopefully portable enough
* If no QT4, QT3 will by tried instead
* Classes renamed using qt3to4
  * If build using QT3 renamed to QT3 class names using defines
* ConfigInfoView::menu has to be renamed as QT4 moc strips struct from
  struct menu and creates a name conflict
* QT2 support has been dropped
* The hidden options inserted in 39a4897c1bb66e8a36043c105d7fd73d8b32b480
  are use in native API

Signed-off-by: Alexander Stein <alexander.stein@informatik.tu-chemnitz.de>
---
Changes in v2:
* Use QT3 as fallback if no QT4 is available
* Rename class names using defines for QT3

Changes in v3:
* based on git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild-2.6.git
  kconfig branch
  * Proper support for hidden options from 39a4897c1bb
  * slightly rework Makefile detection to use pkg-config for QT4 detection
  * Removed USE_QT3 usage, use QT_VERSION instead
  * Drop QT2 support

Changes in v4:
* fixed commit message wrt qmake <-> pkg-config
* fix if branching after pkg-config check
