## [2018-04-11update]QRCode Powered Support QWidgets And QML(qml1 and qml2) Module
Designing cool, interactive interfaces. DuoDuoZhijiao came up with a much better answer for QtQuick1QREncode: `QWidgets QML`, 
a Widget And a declarative language perfect for designing UIs (and much more). 
Here's a sample of how QtQuick1QREncode Plugin For QML looks like:

![No Logo](http://7qn7mv.com1.z0.glb.clouddn.com/_ddui22.png)

## Attention Please

*  You should install those plugin to Qt SDK  path like :make install or Use qtcreator's install command

```
//QML2 code
import QtQuick 2.3
import com.duoduo.component 1.0
    QtQuick2QREncode{
        id:qr
        width: 128
        height: 128
        qrSize: Qt.size(width,width)
        anchors.centerIn: parent
        qrData:"duoduozhijiao" //encode contents
        qrForeground: "#29aee1" //encode color
        qrBackground: "white"
        qrMargin: 2
        qrMode: QtQuick1QREncode.MODE_8    //encode model
		qrLevel: QtQuick1QREncode.LEVEL_Q // encode level
        qrLogo: "qrc:/256.png" //or local path or qrc path but not network url
        onQrSaveFileChanged: {
            console.log("We get save file path is :"+qrfilepath)
        }
    }
```

```
//qml1 Code:
import QtQuick 1.0 //notice here
import com.ddui.qmlcomponents 1.0

Item {
    width: 256
    height: width
    visible: true
    QtQuick1QREncode{
           id:qr
           anchors.fill: parent
           qrSize: Qt.size(width,width)
           qrData:"www.heilqt.com" //encode contents
           qrForeground: "#29aee1" //encode color
           qrBackground: "white"
           qrMargin: 4
           qrMode: QtQuick1QREncode.MODE_8    //encode model
           qrLevel: QtQuick1QREncode.LEVEL_Q // encode level
           qrLogo: "qrc:/Apple.png" //or local path or qrc path but not network url
           onQrSaveFileChanged: {
               console.log("We get save file path is :"+qrfilepath)
           }
           onQrSizeChanged:{
               console.log("Size get save file path is :"+qrsize.width)
           }
       }
    onWidthChanged: {
        if(width>height){
            qr.setQrSize(Qt.size(height,height))
        }else{
            qr.setQrSize(Qt.size(width,width))
        }
    }
}
```

```
//this is a widgets Code
#include <QApplication>
#include "dduiqrwidgets.h"

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    DDuiQRWidgets w;
    w.resize(400,100);
    w.show();
    w.setQrSaveFile("xxx.png");
    return app.exec();
}
```

This project aims at bringing the power of QtQuick1QREncode to qml designer UI and widgets.
