Add child to ScreenSpaceCanvas2D after construction

[royibernthal]

Is there a way to add a child to ScreenSpaceCanvas2D after its already been constructed?

I tried this for instance but it doesn't seem to be the direction:

var text = new BABYLON.Text2D("Test", {
            id: "text",
            marginAlignment: "h: center, v:center",
            fontName: "20pt Arial",
        });

ui.children.push(text);
text.parent = ui; //TypeError: setting a property that has only a getter

Something like this maybe ? http://babylonjs-playground.com/#2AVSFH#55
Press a key to add a new text.

Edit : without a group here: http://babylonjs-playground.com/#2AVSFH#56

Is there a way without specifying the children or parent in any constructor?

In other words, add child to parent after both are already constructed.

I don't think so... But you can always build a group dynamically.

What do you mean?

[Temechon]

You can create the canvas and the text2D. When you decide to add it, build a group2D with parent=canvas, and set the text2D as a child.

I understand, true. Thanks

Hello, no unfortunately right now it's all at construction time because the relation is immutable...I know this is a limitation, I've just created a trello card to remember about it and develop it when I'll have the time to. https://trello.com/c/0KTDa7mM

Hi, that's good to know thanks.

I don't know how the engine works under the hood so it might not be an option, but it'd be great if scene wouldn't have to be passed in 3D constructors as well.

Well, this is a totally different thing. I'm not sure it will happen one day but I can't speak on the behalf of @Deltakosh. Scene objects are tightly coupled to the scene itself, making them independent would be a pretty big rework for a small benefit, I'm not sure it's worth the shot.
