Context object being available to JS

[allbabel]

Hi,

I have added an object to my context and this is available from the QML as such:

@
_engine->rootContext()->setContextProperty( "Proxy", _proxy );
@

and this works great in QML:

@
property variant size: Proxy.getFunction1()
@

If I try to use it in a JS file that is included in my QML as such:

@
function function2() {
Proxy.function2();
}
@

I get the following error:

qrc:/qml/js/uni.js:17: ReferenceError: Can't find variable: Proxy

Can't I add an object reference which is accessible from JS?

Thanks in advance, Andy

Hi Andy,

One solution to the problem is to assign your context object to a javascript object.

For example if you have, in a qml file, something like :
@
import "AppLogic.js" as AppLogic
Page {
id: mainPage
}
@

together with a js like this:
@
var contextObj = ""
///the rest of your JS file
@

You can connect the context obj to "contextObj" at startup in the qml..

@
import "AppLogic.js" as AppLogic
Page {
id: mainPage
Component.onCompleted: {
AppLogic.contextObj = Proxy; //given that Proxy is the obj u added to the context
}
}
@

That way, after startup your JS file you'll have a "bridge" to the context object.
Works for me.. :D

Would that be easy to pass the context obj as a parameter

@
// inside javascript
function doSomething(contextObj) {
...
}

Yep.. would be easier but depending on what you're doing it would be a bit uglier.. or not.. :D
