Is there a way to set a QJSValue as a context property in QQmlContext and
retain function properties?
You should not do this. Context properties are invisible to any tooling
or static analysis of your QML code and add significant complication to
the name lookup logic. The fact that you can inject names into QML this
way is one of the few reasons why we need to version our imports. In Qt6
we aim to move away from this.
I am loading a .js file with QJSEngine::importModule(). The result is
QJSValue object containing all exported functions and properties from the
module.
// file.js
export function someFunction(someArg) {
return someArg;
}
export someVar = "value";
// importing code
QJSValue module = engine->importModule("/path/to/file.js");
Now I want to evaluate JS code snippets with my modules installed. I need
fine-grained control over contexts and my real-world application uses a
context hierarchy. So I use QQmlExpression and set my imported module as a
context property:
Why do you need to do this with contexts? I would suggest a singleton to
hold the QJSValue, or a QML file that imports the JavaScript itself. In
both ways you get a declared name as scope for your script, which avoids
the name injection.
best regards,
Ulf
