unable to have greek characters appear in a text Label

You can also set the Text encoding on the application level and then you have to use tr() tags for every string that you are using.
Check the class QTextCodec
http://doc.trolltech.com/4.1/qtextcodec.html

int main( int argc, char ** argv )
{
 
 
    QApplication a( argc, argv );
    QTextCodec *utfCodec = QTextCodec::codecForName("UTF-8"); //creating new utf-8 codec
    QTextCodec::setCodecForTr(utfCodec);  // setting the utf-8 codec for the tr() tags
 
    FormMain w; // the main window
    w.show();
 
    return a.exec();
}

int main( int argc, char ** argv )
{
    
    
    QApplication a( argc, argv );
    QTextCodec *utfCodec = QTextCodec::codecForName("UTF-8"); //creating new utf-8 codec
    QTextCodec::setCodecForTr(utfCodec);  // setting the utf-8 codec for the tr() tags
    
    FormMain w; // the main window
    w.show();
   
    return a.exec();
}

Before creating the main window create the utf-8 (or the one you need) codec and then set that codec to be used for the tr() tags.

Then in the files all the strings that should be shown should be passed trough the tr() tag.

QMessageBox::critical( 0, tr("КМ Визуелизација") , 
    tr("Не можам да ја пронајдам конфигурациската датотека за боите на шемите:\n %1").arg(Path), tr("Во ред"));

i basically use const char *charArray="/*some chars*/;

for example for the alphanumeric button 2 the corresponding char array is:

charArray2greek="αβγά2" (= alpha,beta,gama,alpha with stress, two)

the reason i used const char is so i can declare whole arrays like above but have the ability to point to just one character.. basically a timed counter counts the number of clicks on each button while cycling through each character in the button's corresponding charArray. then when the user stops clicking a character is picked and output on a label. now when i use greek that character is not shown on the screen, instead i get "??????".

moreover i get the same problem if at runtime i try to set the Text (to smth in greek) of a button. for example on the keypad i also have a button to switch between greek and english.. the text on the button is "Language: English".(in greek with greek characters). now once i press the button the language is switched and the text should also be changed to correspond to "Language: Greek".. well that does not happen.. ie at design time i can input greek characters properly in the text field of a button and of a label but at run time this does not seem to work...

so i am trying to get this utf8 thing straight...
i tried using unicode numbers to write the strings "language: English" and Language: Greek"
it looks basically like: languageButton->setText(tr("\0393\03BB\03CE\03C3\03C3\03B1\003A\0 00D\0395\03BB\03BB\03B7\03BD\03B9\03BA\03AC"));

i thought that wouldmight work.... but then again it does not.. i get the code itself appear on the button.
should i perhaps use smth else instead of tr? shouldi write in unicode or use simple greek characters directly input from the keyboard?

thank you all for your help

Just use QString::fromLocal8Bit() when setting the characters.

greekEdit->setText(QString::fromLocal8Bit(charArray2greek[1]));

greekEdit->setText(QString::fromLocal8Bit(charArray2greek[1]));

this is interesting: i just realised this is happening.
i took this directly from within the designer window.. it appears that if i close the designer and restart it the greek characters don't even appear in the .ui.h file!
i asure you when i type the characters they appear fine... but for some unknown reason when i restarted the pc just now everything that i have typed in greek appears like ??? (exception to this is the text on the buttons which when i open a project in the designer it appears fine)

charGRArray2a="????2";
charGRArray2A="???2";
charGRArray3a="????3?";
charGRArray3A="???3?";
charGRArray4a="?????4";
charGRArray4A="???4";
charGRArray5a="???5";
charGRArray5A="???5";
charGRArray6a="????6";
charGRArray6A="???6";
charGRArray7a="????7$";
charGRArray7A="???7$";
charGRArray8a="????8";
charGRArray8A="???8";
charGRArray9a="????9";
charGRArray9A="???9";

just to make sure:
i have copied all the fonts i found in my ntfs (winXP) partition and installed them both in administrator mode and in personal mode... i mean i think and i hope and i believe i have adequate number of fonts...! or don't i?
