QtJSAPI usage

[andrew]

From a developer:

Can I expose an already existing QMainWindow and access all its children from a .js script?

[andrew]

Yes. You can expose existing QObject objects as you normally would:

Code: Select all

QJSEngine* engine = new QJSEngine();
RJSApi* rjsapi = new RJSApi(engine);

// this makes the Qt classes known to the script engine:
rjsapi->init();

QJSValue global = engine->globalObject();
global.setProperty("appWin", engine->newQObject(appWin));
QQmlEngine::setObjectOwnership(appWin, QQmlEngine::CppOwnership);

In JS, you can then use:

Code: Select all

var w = appWin.findChild('NameOfChild');

or for example:

Code: Select all

var children = appWin.children();
