It works! But you create a QNetworkDiskCache per Image ! It should be better to create one in the same QNetworkAccessMAnager Instance.

Oops, I had forgot to change that. I've updated the disk cache to be static.

How can i use WebImageView when referencing from C++?

For instance, I add the component to QML and want to reference and change properties from C++, for instance I want to use the setUrl function. However, I cant get WebImageView to be recognized in C++.

I did add this line

qmlRegisterType<WebImageView>("org.labsquare", 1, 0, "WebImageView");

I'm kinda new to Cascades, sorry for noob question.

Hi Paratheo, 

All you need to do is

#include "WebImageView.h"

in the c++ class that you want to use it in.

In terms of passing a WebImageView object to C++ from QML, please reference my post on how to pass a Button to C++ from QML: http://supportforums.blackberry.com/t5/Cascades-Development/How-Pass-SIGNAL-object-as-parameter-from...

[Paratheo]

I already had the include there, however your method of passing button to C++ worked great, Thanks!

One more quick question, how can I listen for WebImageView source changed and react to it all in QML?

Also, is there any way to change scaling, for instance to have it 'fill' rather than 'stretch' or 'fit'

You could simply monitor the WebImageView.url property through another object. 

Alternatively, when the url changes, urlChanged is emitted. I think that you could connect to it by using the id of your WebImageView, for example, in the page you could define

onCreationCompleted: {
    idOfWebImageView.urlChanged.connect(myfunction);
}
function myfunction() {
    //logic here
}

In terms of scaling, use the same properties as you would for an ImageView since it is the super class of WebImageView: https://developer.blackberry.com/cascades/reference/bb__cascades__imageview.html#scalingmethod

This is more than awesome. Thanks a lot.

I have an error I do not understand.

"module" org.labsquare "is not installed
     org.labsquare import 1.0 "

I install the module?

[bbkeeper]

Just ignore that annoying issue. Your app will work regardless of that.
