I want to make Krita scriptable, maybe with QJSengine. I'm trying to give
the js engine access to the existing objects in Krita: the images, documents,
windows etc.
From the documentation, I though I would have to use QJSEngine.newQObject, but
that takes ownership and deletes the objects as soon as the engine goes out
of scope.
I thought it would work like the way one can register existing objects with
registerContextProperty()...
Here is what I'm trying to do:
{
QString script = m_scriptEditor->ui->txtScript->document()->toPlainText();
if (script.isEmpty()) return;
QJSEngine engine;
engine.installExtensions(QJSEngine::AllExtensions);
if (m_canvas) {
QJSValue canvas =
engine.newQObject(dynamic_cast<KisCanvas2*>(m_canvas));
engine.globalObject().setProperty("currentCanvas", canvas);
}
QJSValue part = engine.newQObject(KisPart::instance());
engine.globalObject().setProperty("KisPart", part);
QString output = engine.evaluate(script).toString();
m_scriptEditor->ui->txtOutput->document()->setPlainText(output);
}
