Linguist: how to dynamically switch language of all UI?

[brucezcg]

Question 1) What is the simple way to do this?
Question 2) For example: 
class ZWgtItem::public QWidget{
private:
 QLabel * mMainTitle,*mSubTitle;
}

I had many ZWgtItem widget items, so how to translate when change language?

Thanks.

Hi,

It's described in the Internationalisation chapter in Qt's documentation.

@SGaist Thanks, but this is not suitable for me.

I had so many ZWgtItem widgets dynamically new from source code.
So it would be awful to do translate like this:

changeEvent(){
******
QVector<ZWgtItem*> wgtlist;
//Language change
for(int i=0; i<wgtlist.length(); i++){
if(i==0)
wgtlist[i].setMainTitle(tr("xxxxx"));
else if(i==1)
wgtlist[i].setMainTitle(tr("yyyyy"));
else if(i==2)
wgtlist[i].setMainTitle(tr("zzzzz"));
.................

    }

}

Hi
That IS the only way of doing dynamic language changing. ( reset the text again so TR macro can lookup new text)
Alternatively, you can restart the application.
