qmake and localization

[mousa_mk]

In that case you can move the definition of QTranslator object into your main window class (or everywhere else, just somewhere that'll keep it) and load it like before:

at mainwindow.h file:

private:
QTranslator translator;

private:
QTranslator translator;

To copy to clipboard, switch view to plain text mode 

In MainWindow's constructor before setupUi():

translator.load("path/to/qm/file/cs_CZ.qm");
qApp->installTranslator(&translator);

translator.load("path/to/qm/file/cs_CZ.qm");
qApp->installTranslator(&translator);

To copy to clipboard, switch view to plain text mode 

When you want to change language at runtime you just load the new language and retranslate the ui:

translator.load("path/to/qm/file/en_US.qm");
ui->retranslateUi(this);

translator.load("path/to/qm/file/en_US.qm");
ui->retranslateUi(this);

To copy to clipboard, switch view to plain text mode 

This way, you install the translator once and just change it's loaded language whenever needed.

I just wanted to load the appropriate translation according to the system locale in the first startup. I did it reading the documentation.

Thank you very much.
