Hi,
I'd like to expose an API within a QJSEngine JavaScript environment
for an asynchronous callback.
Thus I want to expose a method "regCallback":
foo.regCallback(function() { alert("Hello"); })
and allow C++ to call that function at some later point. The function
is exposed as a QJSValue, thus I'd expect a class Foo to look
something like this:
class Foo: public QObject
{
public:
Q_INVOKABLE void regCallback(QJSValue someFunction) { m_f = someFunction; }
void doCallback() { m_f.call(); }
private:
QJSValue m_f;
};
However this doesn't work; regCallback never gets called. Is there
some other way to achieve this API?
Gav.
