Some strings can't be translated in the qt project.

[BigCroby]

In my qt project, there are some strings can't be translated, such as the following code:

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

QTranslator trans;
trans.load("gui_zh");
QApplication::installTranslator(&trans);
ui->retranslateUi(this);

}

MainWindow::~MainWindow()
{
delete ui;
}

void MainWindow::on_pushButton_clicked()
{
QString fileName = QFileDialog::getOpenFileName(this, tr("open"), QDir::currentPath(), "*.cpp");
}

the "open" string , be used in getOpenFileName() function, can't be translated to Chinese string "打开", but other strings, like the pushButton text, can be translated to Chinese string. There is the "Q_OBJECT" in my class, and I have generate *.qm file. I don't know why some stings can be translated, but other strings can't. May I ask for a favor, Thanks!

Hi and welcome to devnet,

Are you doing dynamic translation with your application ? Or only when starting it ?

Only when starting it, not dynamic translation .

Are there some differences between dynamic translation and only when starting it?

You should move the translator related code in your main function. The translator must be installed before creating any widgets. Have a look at the QTranslator documentation for more information
