Translation is not working through JavaScript function

Sanjeev Gudisagar

I am doing language translation in qml, i have three text objects, if i directly assign the values and do the translations it works fine, but if i change the values of a text fields through JavaScript function then apply the translations it is not working.

It could be issue with property binding. Binding has to re-evaluate for the translation to work. Do you have sample program for us to check ?

Hi,
You should show your function and how you are doing it in qml so someone can help..
You can use QtLinguist for translations.

@dheerendra This is my sample code, Once the button is clicked i am calling JavaScript function, i am changing all the text values after that i am translating, the translation is not working

Column {
        spacing: 10
        anchors.centerIn: parent
        Text {
            id : t1
            text :cm.buttonText + trans.lang
        }
        Text {
            id : t2
            text :cm.buttonT1 + trans.lang
        }
        Text {
            id: t3
            text :cm.buttonT2 + trans.lang
        }
        Button{
            text : "German"
            onClicked: {
                MyScript.changeValue();
                trans.selectLanguage("de");
            }
        }
    }

trans - Is it object coming from C++ side ? If yes, is this method is really called ?Can you confirm ? Can you show me your setLanguage method ?

Sanjeev Gudisagar

I have the following code in the function. this function is called i verified it with debugs.

    if(language == "de") {
        qDebug() << Q_FUNC_INFO << " Germany Language " << endl;
        translator->load("");
        translator->load("://de.qm");
        QCoreApplication::instance()->installTranslator(translator);
        engine->retranslate();
    }

dheerendra

This method looks correct from translation perspective. I'm assuming that appropriate translations exist in de.qm files. what changes are you doing in changeValue() method ? Can you show the function ?

Sanjeev Gudisagar

@dheerendra said in Translation is not working through JavaScript function:

changeValue()
Whatever i am changing in changeValue() function is not getting translated.

function changeValue() {
    t2.text = cm.buttonT4
    t3.text = cm.buttonT5
    t1.text = cm.buttonT3
}

dheerendra

hmm. You are doing the property bindings in javascript methods. This will not work. Can you try the following ?

t2.text = Qt.binding(function() { return cm.buttonT4;})

Sanjeev Gudisagar

After replacing this like above its working now... Thank you @dheerendra

dheerendra

Cool. If you want to property binding trigger, you should call Qt.binding explicitly. Since issue is resolved you can move the case to "SOLVED" state.
