Hello, I use QWebEngineView for render my HTML page and QWebChannel for
communicate with my JS code. I can pass QVariant type into JS code as signal
parameter or function return value. But I need to pass custome class object. I
wrote the class and inherit it from QObject like this:#include <QObject>class
test : public QObject{Q_OBJECTpublic:test() : QObject(nullptr) {}test(const
test&) : QObject(nullptr) {}test(QObject *parent) : QObject(nullptr) {};int a;
int b;
};Q_DECLARE_METATYPE(test);
than I registered type as:qRegisterMetaType<test>();and emit signal:test t;t.a
= 666;t.b = 454;emit home_page_controller.MySignal(t);In JS code I connect to
signal ant try to show received
data:document.addEventListener("DOMContentLoaded", function (){new
QWebChannel(qt.webChannelTransport, function
(channel){window.home_page_controller = channel.objects.home_page_controller;
window.home_page_controller.MySignal.connect(function(struct)
{
alert(struct)
})
});
});But instead [Object] I recived null.Next my step - add my structure into
QVariant:QVariant var;test t;t.a = 666;t.b = 454;var.setValue(t);emit
home_page_controller.MySignal(var);But null received again. How I can to pass
custome data into JS code? Thanks. _______________________________________________
