[Interest] Call retranslateUi() from UI generated/loaded directly from *.ui
Hi, I am developing an application where I am generating the UI via loading the *.ui rather than using uic to generate the source/header file. I need to call retranslateUi to update my translation but most documentation talks about a generated method by uic e.g. void retranslateUi(QWidget *Form) In my situation, how should I retranslate my UI ?

Re: [Interest] Call retranslateUi() from UI generated/loaded directly from *.ui
I tried enabling setLanguageChangeEnabled(true) but I don't see my label
updating, do I have to write some handler for that event and go through to
update each widget text ? Apologies, I am new to translation.
```
#include "MainWindow.h"
#include
#include
#include
#include
#include
#include
MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent)
{
QUiLoader loader;
QFile file(":/designer/mainwindow.ui");
file.open(QFile::ReadOnly);
QWidget *widget = loader.load(&file, parent);
loader.setTranslationEnabled(true);
file.close();
setCentralWidget(widget);
ui_checkBox = findChild("checkBox");
QObject::connect(ui_checkBox, SIGNAL(clicked()), this, SLOT(doCheckBox()));
}
void MainWindow::doCheckBox() {
qDebug() << "doCheckBox() called = " << ui_checkBox->isChecked();
if (ui_checkBox->isChecked())
{
QString langFile = QString(":/language/.qm/mlc_de.qm");
QTranslator translator;
if (translator.load(langFile)) {
qDebug() << "DE Successful";
bool installed = qApp->installTranslator(&translator);
if (installed) {
qDebug() << "DE installed";
}
}
else
{
qDebug() << "DE Unsuccessful";
}
}
else
{
QString langFile = QString(":/language/.qm/mlc_C.qm");
QTranslator translator;
if (translator.load(langFile)) {
qDebug() << "C Successful";
bool installed = qApp->installTranslator(&translator);
if (installed) {
qDebug() << "C installed";
}
}
else
{
qDebug() << "C Unsuccessful";
}
}
}
```

Re: [Interest] Call retranslateUi() from UI generated/loaded directly from *.ui
Did you try "loader.setTranslationEnabled(true);" before loader.load?

It should automatically react to language change events, see:
