öüä not working in qt4-apps on linux

[niko]

Hello,

I'm using Qt 4.2.2 on Gentoo Linux. My problem is that I can't insert öüä characters in textboxes. Characters like é Ã* (using ´+e) work.

I have no problems in all KDE-Applications.

Any tipps how I can find the cause of this problem?

thanks, niko

PS: This is my very simple test-code:

#include <QtGui>
int main(int argc, char** argv) {
    QApplication app(argc, argv);
    QLineEdit lineEdit;
    lineEdit.show();
    return app.exec();
}

#include <QtGui>
int main(int argc, char** argv) {
    QApplication app(argc, argv);
    QLineEdit lineEdit;
    lineEdit.show();
    return app.exec();
}

Are you able to copy & paste those characters into the lineedit?

[niko]

no - doesn't work either.
i copied the title of this thread in it and go the attached result.

tanks for your help...

The problem is probably with your system then. I can paste the characters fine here on Linux. Maybe you're using a font that doesn't have these glyphs?

[niko]

i didn't change default fonts anywhere.
qtconfig says "Sans Serif"
and in kde sans serif has these characters.

I tried the same thing on another desktop (also gentoo) - no problem there!

[niko]

I changed the default font to Times New Roman in qtconfig.
No change.

Ist this QT build from your self? on system locale latin utf-8 ... sample german utf-8?
Or ist this an emerge gentoo ready package... ? configured on only utf-8?


wahts happen wenn you start èèèè char as argumen 1 and 2

./app üöäüöä öäìüöä

on this ....
on pro file...
CONFIG += console

#include <QApplication>
#include <QtGui>
#include <QtCore>
#include <QDebug>
 
      int main(int argc, char** argv) {
 
          QApplication app(argc, argv);
 
          QString argument_1, argument_2;
          argument_1 = QString::fromLatin1(argv[1]);
          argument_2 = argv[2];
          qDebug() << "fargument_1 -> " <<  argument_1;
          qDebug() << "argument_2 -> " <<  argument_2;
 
 
          QLineEdit lineEdit;
          lineEdit.setText (argument_1+argument_2);
 
          lineEdit.show();
          return 0;
      }

          argument_1 = QString::fromLatin1(argv[1]);

Can you run the character map example (bundled with Qt) and see if the glyphs you seek are present there?

[niko]

Ist this QT build from your self? on system locale latin utf-8 ... sample german utf-8?
Or ist this an emerge gentoo ready package... ? configured on only utf-8?

It is the current stable gentoo-package built with:

[ebuild R ] x11-libs/qt-4.2.2 USE="cups dbus debug doc examples gif jpeg opengl png qt3support sqlite xinerama zlib -accessibility -firebird -glib -mng -mysql -nas -nis -odbc -pch -postgres -sqlite3" INPUT_DEVICES="-wacom" 0 kB

nothing else is special configured.

my /etc/locale.gen file:

en_US ISO-8859-1
en_US.UTF-8 UTF-8
de_DE ISO-8859-1
de_DE@euro ISO-8859-15
de_DE.UTF-8 UTF-8
de_AT ISO-8859-1
de_AT@euro ISO-8859-15
de_AT.UTF-8 UTF-8

en_US ISO-8859-1
en_US.UTF-8 UTF-8
de_DE ISO-8859-1

de_AT ISO-8859-1
de_AT@euro ISO-8859-15
de_AT.UTF-8 UTF-8

To copy to clipboard, switch view to plain text mode 

Where else can I configure something?
(I don't remember I did)

./app testüöäüöätest testöäìüöätest

./app testüöäüöätest testöäìüöätest

To copy to clipboard, switch view to plain text mode 

gives me this:

fargument_1 ->  "testtest"
argument_2 ->  "testtest"

fargument_1 ->  "testtest"
argument_2 ->  "testtest"

see screenshot - i think these are the right ones. (qt4 on the left, kcharselect on the right)

this is my result on XUBUNTU Linux feysy or so....

./app testüöäüöätest testöäìüöätest

argument_2 ->  "testöäìüöätest"

utf-8 out ...


Your default font locale not speak utf-8?? configured to qt... and bypass unknow char....

QFont f( QApplication::font () );
qDebug() << "### default font -> " << f.family (); /* this font is buggy */

### default font -> "Sans Serif" work on my OS


i am sure if you rebuild qt4.2 from normal method .... all running ...
whitout emerge or so....

I found the issue, I did't have LANG set and so this bug effected me:

solution: upgrade to 4.2.3
or set LANG enviroment variable

thanks for your help!
