Qt tr() not working if i am using in static member
#1 Please let me know why it is not working i am new in Qt. here is the code
static const QString str;
const QString Transl::str = QObject::tr("Hello world");
// const char* const gstr = "Hello World";
int main(int argc, char *argv)
QApplication app(argc, argv);
QPushButton *button = new QPushButton(); button->setText(Transl::str); // button->setText(tr(gstr)); // This is also throw error "error: ‘tr’ was not declared in this scope" button->resize(100,100); button->show() return app.exec();
My trans_la.ts file contains this which i generate by lupdate.
<location filename="main.cpp" line="10"/>
<translation>Orbis, te saluto!</translation>
Then I do lrelease which generate trans_la.qm. But when i run my executable instead of showing the translated string it shows "Hello world". Please suggest me why it is not working.
#2 Also if you see i have commented two lines(11th and 22nd) where I am trying to use with constant char* global variable where it thows error tr() was not declared in the scope.
Qt tr does not work on static constant members. use QT_TR_NOOP instead tr.
@const QString Transl::str = QT_TR_NOOP("Hello world");@
hi @dasun i tried QT_TR_NOOP("Hello world") in that case lupdate is not working it ask tr is not working without any context. Please help :). Also can you figure out about the error of #2 why tr() is giving me error ?
Main function is not an QObject. tr defined in QObject.
You can use @QObject::tr("Hello World");@
Hi and welcome to devnet,
IIRC, for static text like that it's QT_TRANSLATE_NOOP that should be used
Hi @SGalst what actually QT_TRANSLATE_NOOP will do ? will it work on translation ?
A little search in the documentation would have returned the "explanation":http://qt-project.org/doc/qt-4.8/linguist-programmers.html#using-qt-tr-noop-and-qt-translate-noop
hey thanks for the valuable info. but i still did not find the solution of #2 why it is giving me error. well i'll try to look more in documentation. Thanks
It simple: tr is a method of QObject and main is a function not a QObject
