Checking the image state

[ Edited ]

Hi all, I'm trying to show image after loading, but nothing happens, white screen observed. I'm using example code from the documentation , but it doesn't work! Is it a bug or I'm doing something wrong?

        ImageView {
            id: myImageView
            attachedObjects: [
                ImageTracker {
                    id: tracker
                    imageSource: "asset:///images/bigpic.jpg"

                    onStateChanged: {
                        if (state == ResourceState.Loaded) {
                            myImageView.image = tracker.image
                        }
                    }
                }
            ]
        }

Re: Checking the image state

I have never used ImageTracker. But the ImageView works for me.

 

ImageView {
    verticalAlignment: VerticalAlignment.Center
    imageSource: "asset:///images/image.png"
scalingMethod: ScalingMethod.None }

 Maybe, your image is scaled to the size of one single pixel if it does not have enough space.

Re: Checking the image state

The imageTracker does have some issue...  I have felt the same issue in one of my previous projects...  Someone else had also reported the same .. a while back
