UNICODE UTF-8 String in QT + Eclipse?????

[thaihoangluu]

I use Eclipse IDE for C/C++ & QT integration plug-in , but I can not write in Unicode font ?
How to resolve ? Thank every body.
Example: I write : "Chà o tất cả các bạn!" but It show in program: "Chà o t?t c? các b?n"

Hello.
Are You create console application? In IDE displays all right?

HÃ*c.
I use QpushBotton,... not display utf - 8

Ok.
I have done so:
1. Check code page in Eclipse, maybe it different from system code page.
if code page is ok, try to use next:

QTextCodec *incodec = QTextCodec::codecForName ("CP1251"); // change "CP1251" to our code page
 QTextCodec::setCodecForTr(incodec);
 
//in module with pushbutton 
 
 QPushButton *button = new QPushButton( tr("Chà o tất cả các bạn!"), this);

QTextCodec *incodec = QTextCodec::codecForName ("CP1251"); // change "CP1251" to our code page
 QTextCodec::setCodecForTr(incodec);

//in module with pushbutton 

 QPushButton *button = new QPushButton( tr("Chà o tất cả các bạn!"), this);

To copy to clipboard, switch view to plain text mode

You can display your text without changing codec:

#include <QApplication>
#include <QLabel>
 
int main(int argc, char **argv) {
    QApplication app(argc, argv);
    QLabel label(QString::fromWCharArray(L"Chà o tất cả các bạn!"));
    label.show();
    return app.exec();
}

#include <QApplication>
#include <QLabel>

int main(int argc, char **argv) {
    QApplication app(argc, argv);
    QLabel label(QString::fromWCharArray(L"Chà o tất cả các bạn!"));
    label.show();
    return app.exec();
}

To copy to clipboard, switch view to plain text mode 

Edit:
this is not really good, because of dynamic translations, but this should work ok:

#include <QApplication>
#include <QLabel>
 
int main(int argc, char **argv) {
    QApplication app(argc, argv);
    QLabel label(Qbject::trUtf8("Chà o tất cả các bạn!"));
    label.show();
    return app.exec();
}

#include <QApplication>
#include <QLabel>

int main(int argc, char **argv) {
    QApplication app(argc, argv);
    QLabel label(Qbject::trUtf8("Chà o tất cả các bạn!"));
    label.show();
    return app.exec();
}

edit 2:
try to call QTextCodec::setCodecForTr(QTextCodec::codecForName ("UTF-8")); in your main() function, then you should be able to use regular tr("") method:

#include <QApplication>
#include <QLabel>
 
int main(int argc, char **argv) {
    QApplication app(argc, argv);
    QTextCodec::setCodecForTr(QTextCodec::codecForName("UTF-8"));
    QLabel label(Qbject::tr("Chà o tất cả các bạn!"));
    label.show();
    return app.exec();
}

#include <QApplication>
#include <QLabel>

int main(int argc, char **argv) {
    QApplication app(argc, argv);
    QTextCodec::setCodecForTr(QTextCodec::codecForName("UTF-8"));
    QLabel label(Qbject::tr("Chà o tất cả các bạn!"));
    label.show();
    return app.exec();
}

Your have error in code:

QLablel lable (Qbject::tr(...));
//rigth path this
QLablel lable (QObject::tr(...));

QLablel lable (Qbject::tr(...));
//rigth path this
QLablel lable (QObject::tr(...));

You missed "O" in QObject.
