Hi,

I’m having trouble with the MultiResolutionImage component. Two examples, where the first one works fine, but the second doesn’t.
```
// Works fine, it's selecting "qrc://+hd2/MyImage.png" respectively.
MultiResolutionImage {
  id: image
  source: "qrc:/MyImage.png"
}

// This doesn't work at all. It's not changing the source depending on resolution.
MultiResolutionImage {
  id: image
  source: myObject.image // "qrc:/MyImage.png"
}
```
Either I’m too stupid to see my mistake or it’s a bug.

Hi supaiku,

can you provide more information on the second case (where it doesn’t work)?

What does myObject.image refer to? Is it a string property that contains the image source?
Do you have access to this property in the context of the MultiResolutionImage?

Best,
GT

Hi,

well the property contains what the comment says. :p It’s content is a string to the qrc location.

The MultiResolutionImage is loading a source, but not from a “+hd/+hd2” folder as in the first example. It works if I put the exact same string into the source, but not if the source is provided by a property binding.

MyObject is a simple JavaScript object.

Hi,

I just tried both examples on my end, and everything works fine. I just happened to have one problem at first, when I created the “myObject” javascript-object as a QML property and used the wrong syntax:
```
// correct
property var myObject: {
        "image": "qrc:/MyImage.png"
}

// wrong
property var myObject: {
        image: "qrc:/MyImage.png"
}
```
Maybe that’s also your problem?

If not, can you please provide some log output or hints to the error that you are facing?

Best,
GT

qrc:
```
<RCC>
    <qresource prefix="/assets">
        <file alias="pic.png">assets/pic.png</file>
    </qresource>
    <qresource prefix="/assets/+hd">
        <file alias="pic.png">assets/+hd/pic.png</file>
    </qresource>
    <qresource prefix="/assets/+hd2">
        <file alias="pic.png">assets/+hd2/pic.png</file>
    </qresource>
</RCC>
```
```
MultiResolutionImage {
  source: jsonObject().source
  onSourceChanged: {
    console.log("Source: %1".arg(source))
  }
}

function jsonObject() {
  return { source: "qrc:/assets/pic.png" }
}
```
This is 100% reproducable.

Hi,

it works for me if I define my resources like that:
```
<RCC>
    <qresource prefix="/">
        <file>qml</file>
		<file>assets</file>
		<file>assets/+hd</file>
		<file>assets/+hd2</file>
    </qresource>
</RCC>
```
Cheers,
Alex

Hi,

if I use the same example I posted above with the qrc you posted, it still doesn’t work. 🙁

Hi,

can you please send a full project containing the issue to support@felgo.com? Maybe there are still inconsistencies regarding the project structure or something else.

Cheers,
