How to clear or delete Image in QML

Hello.
How to clear or delete Image in QML?

I'd like to make the application.
it likes "slide show" application.

example

Image {
    id: mPicture
}
Timer {
    interval: 2000
    running: true
    repeat: true
    property var fList //it has many imagefile path ex. aaa.png, bbb.png...
    property int nextIdx
    onTriggered:{
        mPicture.source = "file://" + fList[nextIdx]
        nextIdx++
        if(fList.length <= nextIdx) {
            nextIdx = 0
        }
    }
}

It's working.
but few minutes later application will down.
I think I have to clear or delete mPicture.source.

I already try it.

    mPicture.source = ""
    mPicture.source = "file://" + fList[nextIdx]

But it's same.

Could you let me know how should I do?
thanks.

@nishiokas most likly you indexing fList wrong and outrun the length.

However I would suggest taking a look the the SlideShow-Example from the docs.

That should help you more.

@J-Hilk
Thanks for reply.
I'm sorry I didn't take more information.
"fList" has many image file.
and the application is working.

I would not big change to the application.
I'd like to know how to clear image.

Thanks for your help!

Simply updating the mPicture.source should be sufficient to release any resources consumed by the previously displayed image; there's no need for any additional code to explicitly "clear" it.

What's the exact nature of "application will down"? Do you get an error message on the console? If it's a crash, where does a stack-trace say it crashes?
