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);

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();
}


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();
}


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();
}

It's code Error :(

Your have error in code:



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


You missed "O" in QObject.
