Hi there !
I've got a nice C++ Object Wrapped Window. The C++ pointer is stored in the
#0 internal field.
I can create some Window in JS like this :
wnd = new Window (parent);
wnd.text = "Hi there!"; // trigger an C++ accessor
This works just fine.
Then I want to create a derived class from my Window, but in JS, not in C++.
If i do :
function MyWindow(parent) {
Window.call(this, parent);
}
MyWindow.prototype.__proto__ = Window.prototype;
MyWindow.__proto__ = Window;
mwnd = new MyWindow(parent);
I got an error while Window.call, be cause the new object has no internal
field.
So I've tried this :
function MyWindow(parent) {
this.__proto__.__proto__ = new Window(parent);
}
MyWindow.__proto__ = Window;
mwnd = new MyWindow(parent);
And it's nearly working.
The problem is when I try to set a value into the wrapped Window with an
accessor:
mwnd.text = "Hi there!";
The accessor of Window is not triggered, instead, "Hi there!" is just
stored in the text property of mwnd.
So my question is : How to properly inherit a C++ Wrapped object in JS ?
Best regards,
Florent
