Is it possible to Dynamically change the language of Qt Control 2 app using Linguistic, lupdate, .qm,.ts files.

Cool, thanks for feedback. Happy coding! (and if the issue is indeed solved, please mark this thread as solved, too. Maybe it will help somebody else, too)
Sure :)

@sierdzio Yeah.....But this simple method is very easy to implement. You just have to note that..every text in qml should change according to the corresponding property. Every distinct text should have distinct property.Its lengthy but works. I applied and its working fine. Thanks mate. It helped a lot.
Its just same as including a .ts and .qm file in project. There it automatically pics the lines you have to change and here You have to go through your project for getting the lines to be changed.

Why it needs distinct property for each text?

There is a way to force each string to be updated when you change the language.
Define "empty" property and attach it to all your strings.
// C++ side. Expose this property to QML via root context, or QML singleton - whatever Q_PROPERTY(int empty READ empty NOTIFY emptyChanged) // QML side text: qsTr("Some translatable text") + emptyNow, when you change the translation (.qm file), just emit EmptyChanged() signal. You don't need to change it's value, just emit the signal. All strings will be reloaded.
@sierdzio curios:
BlackBerry10 Cascades did something similar ;-)

Hey thanks for pointing out the mistake. Now everyone will find me fool....but anyway
here is what I was doing->I was using QProperty as a String and using signal to change the text. Giving that string property a already translated text. And changing on a click of a button.Thanks for pointing out the mistake sir. Now only empty property is to be added for every qsTr() string. I used the changes and project is working fine.
But on thing is remaining there. 0 number is added automatically at the end of the text,this is because I am using int property. Well I will do my own experiments and update when It will be working properly.
Am sorry for my mistake.Thanks again

Using QString in place of int for Q_PROPERTY, it worked. Thanks to all.

It does not. You can use the same "empty" property for all strings.

Yeah, I used int to save me some typing ;-) Using an empty string is much better, indeed, it won't give you an "0" appended to all texts.

I knew that already, I just wondered why Akshay said so, and he then noticed it, too :)

Ah, ok, sorry :-)

Hi,
For a simple tutorial on this issue, have a look at this: https://v-play.net/doc/howto-multi-language/
The tutorial uses the V-Play SDK, but it works the same way for standard Qt apps.
Cheers,

Thanks Everyone for helping me out. Now am having a running project. This is a topic whose solution can not be found easily. So here I uploaded my project in Github. So the beginners can have a look at it. It is the most simplest project that I can make.
Sorry for the naming of the project and files. :p
