How to give source file path for image when using repeater in qml??

Repeater
{
    model:4
    Rectangle
    {
        x:xarray[index];
        y:yarray[index];
        width:widtharray[index];
        height:heightarray[index];
        Image{
           source:img1_array[0]; 
        }
    }
}

In the above code all the arrays are declared in cpp,using context property it is used in qml.For source I want to change the total array based on the repeater change ???Any suggestions to solve this??

@Bharathi

For source I want to change the total array based on the repeater change ?

It is not quite clear what you are trying to do ? Do you mean you want to modify the whole C++ array even if there is 1 change in the array ?
May be you should check for onModelChanged handler ?

@p3c0
Sorry for the inconvinience I am having 4 different arrays for 4 different models.But I am struggling to use it in repeater

Repeater{
Model:4
Image{
//for 1st model I want the source as 
  source:img1_array[0];
//for 2nd model I want the source as
   source:img2_array[0];
//for 3rd model I want the source as
   source:img3_array[0];

}
}

@Bharathi What is img1_array[0] and so on ?
What does it return ?
How is it exposed from C++ to QML ?

Bharathi

@p3c0 img_array[0] It just return local file path as string from c++ to display the image.img_array is declared as string list in c++.

p3c0

@Bharathi You can't access string list directly from QML unless make it accessible from C++.
Have a look at following:
http://doc.qt.io/qt-5/qtqml-cppintegration-exposecppattributes.html
http://doc.qt.io/qt-5/qtqml-cppintegration-contextproperties.html

Perhaps you should add a Q_INVOKABLE function in the model which will return the path from your string list depending upon the index.
