Qt version 4.6.2 and GTK (GtkStyle - qgtkstyle)

[zAchAry]

URLs:
qgtkstyle - A Qt 4 style that renders using GTK
Trolltech Labs page

Warning: This page is here for historical purposes. Since Qt 4.5, QGtkStyle has been shipped as part of the official Qt distribution. If you have any bugs or issues to report, please report them on the official Qt bugreport forum:

http://bugreports.qt.nokia.com/secure/Dashboard.jspa

The style requires Qt 4.3 (though 4.4 is preferred) and GTK+ 2.0 or higher. It intends to make Qt applications blend perfectly into the GNOME desktop environment by using GTK to render all components.

Selecting GTK+ theme in Qt Configuration gives this error:

Code: Select all

$ qtconfig 
QGtkStyle was unable to detect the current GTK+ theme.

(process:23853): Gtk-CRITICAL **: gtk_widget_style_get: assertion `GTK_IS_WIDGET (widget)' failed

Anyway to make Qt4.6 to use GTK+ 2 themes?

Edit: my Qt package is from:
qt-4.6.2_2d3d3e5-i486-1.txt
qt-4.6.2_2d3d3e5-i486-1.txz
qt-4.6.2_2d3d3e5-i486-1.txz.asc

I am not familiar with that Qt tweaking.
But can you maybe try ...

Code: Select all

strace qtconfig 

... to see which files are accessed?
I guess some permission issue or probably missing files...

[zAchAry]

Code: Select all

$ strace -o strace.qtconfig qtconfig
$ grep open strace.qtconfig

http://salix.pastebin.com/q9zbkt5r

Code: Select all

$ which qtconfig
/usr/bin/qtconfig

$ file /usr/bin/qtconfig
/usr/bin/qtconfig: symbolic link to `/usr/lib/qt/bin/qtconfig'

$ file `which qtconfig`
/usr/bin/qtconfig: symbolic link to `/usr/lib/qt/bin/qtconfig'

$ file /usr/lib/qt/bin/qtconfig
/usr/lib/qt/bin/qtconfig: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), stripped

brainstorming to help guessing:
* Qt installation broken
* wrong file permissions
* missing files
* wrong search path for libraries

Please report this issue maybe directly to Slackware due to it is no direct Salix package.

[zAchAry]

Where do I submit a bug report about packages for Slackware?

I don't think there is something wrong with the package, but with your system.

I don't think there is something wrong with the package, but with your system.

What the problem might be, then?
Are you able to use the GTK+ theme rendering feature of Qt with Qt?

Yes, I'm using it since some weeks. Your pastebin has expired but there where a lot of nasty messages about standard libs that could not be opened. Please try to reinstall Qt:
removepkg qt
slapt-get -u
slapt-get -i qt

[zAchAry]

No change, same stuff:

I remember that you said you were using some foreign packages from other locations than only the official Salix repository.
Maybe try to reproduce this weird behaviour on a fresh Salix installation without any foreign packages installed?
