How to exchange data between qt and javascript?

[small_bird]

@jsulm Actually, it is not c++. It is QML and javascript.

[jsulm]

@small_bird Good to know. I already asked you whether you're using QML you said no...
If you're using QML without C++ then I'm wondering how you can use QImage as you asked before?
Take a look at http://doc.qt.io/qt-5/qtqml-javascript-topic.html

@jsulm However, now, I want to exchange data between C++ and javascript.

[jsulm]

@small_bird Then exchange it between C++ and QML (check Qt documentation for this) and from QML then to JavaScript.
Or do you want to remove QML completely?

[small_bird]

@jsulm yes I have done that. But how to exchange qimage from qml to javascript?

[jsulm]

@small_bird I don't know I would say it depends on that JavaScript three.js framework. Check it's API and data types.

[small_bird]

@jsulm No, the javascript's grammar is the same with three.js engine.

[jsulm]

@small_bird What do you mean by "grammar" and "engine"? three.js is a 3D JavaScript framework/library, right? So you need to check its documentation if you want to use it.

[small_bird]

Yes, that's it. I have checked that, but how to transmit qimage data between qml and js function as it is not a inner type?

[jsulm]

@small_bird said in How to exchange data between qt and javascript?:

That's three.js engine is written by javascript.

Sure it is. That's not the point. It has an API, right? See its documentation: https://threejs.org/docs/index.html#manual/introduction/Creating-a-scene
