QTranslater

This crate is a very small translation system based on Json for QMetaOjbect. It was originally created for the translation of the Grace software(by Cairn Devices).

Objectiv

Allow simple translation of variables for interfaces that use the qmetaobject crate.

Setup

In your folder project

Create in a "lang" folder in your src folder. In this "lang" folder create a json file for every languages you want to switch to.

Screenshot

In a Json file

For example in "fr_FR.json" json { "water": "eau", "battery": "Batterie", "trains":"age", "global_infos": "Informations générales", }

In your rust file

By default, the library will determine the language of your computer using "sys-local::getlocal". If the language is not present in the "lang" folder, it will automatically load an "enGB.json". So please provide an "en_GB.json" file to avoid any crash of your application.

```rust //For example: in my main.rs //We start with import* use qmetaobject::prelude::*; use qtranslation::QTranslater;

fn main(){
    /*
    Some code...
    */
    qml_ressources(); 
    qml_register_type::<QTranslater>(cstr!("QTranslater"), 1, 0, cstr!("QTranslater")); //Register the QTranslater type
    let mut engine = QmlEngine::new();
    engine.load_file("qrc:/main/qml/main_window.qml".into()); //"main_window" is just my qml first window.But it can be any other page.
    engine.exec();

}

```

In your QML file

```qml //Import the QTranslater object import QTranslater 1.0

ApplicationWindow{ id:my_window visible:true width : 800 height:800

QTranslater{
    id: lang //Assign an ID you want
    Component.onCompleted: {
        init();
    }
}
//Some code...
ColumnLayout{
    Text{
        text: lang.dict["global_informations"]
    }
    Text{
        text: lang.dict["water"]
    }
    Text{
        text: lang.dict["battery"] + ": 23
        font.bold: true
    }

    Text{
        textFormat: Text.RichText
        text: "<html> <span style='font-weight: bold '>I love</span><span>" +lang.dict.["trains"] + +"</span><\html>"
        color: ""
        font.family: ubuntu_regular.name
    }

    Button{
        text: "Change to French"
        onClicked: lang.change_lang("fr_FR") // To change language
    }
}

}

```
