QmlRegisterType to associate with other types?

Question

Qt

create
qmlRegisterType("myprog",1,0,"MyClass"); and everything is clear here, but let's move on
1. Can it be associated with other types in the c ++ code (signals slots)?
2. Or how to create several classes in one type and access variables in these?

Answer 1

talking about class fields? We take and create.
> and access variables in these
Q_PROPERTY

Answer 2

You might be better off with this: qmlRegisterSingletonType

Answer 3

1. C++ wrote well :)
an example with errors (and everything is wrong XD) but something like this is needed

spoiler

oneclass.cpp
----------------
OneClass : QObject {
...
signals: void mySignal();
}
twoclass.cpp
----------------
TwoClass : QObject {
...
public slots: void mySlot(){};
}
main.cpp
----------------
#include oneclass.cpp
#include twoclass.cpp
...
qmlRegisterType("myprog.one",1,0,"MyClass");
qmlRegisterType("myprog.two",1,0,"MyClass");
QObject::connect(OneClass, SIGNAL(mySignal), TwoClass, SLOT(mySLOT));
2. Precisely classes
oneclass.cpp
----------------
OneClass : QObject {
...
Q_PROPERTY resultData(QString resultText)
public: void calculate(QString text) { resultText = text;}
}
twoclass.cpp
----------------
#include oneclass.cpp
...
TwoClass : QObject {
private:
OneClass *oneClass;
Q_INVOKABLE void biginning(QString startText) {
oneClass.calculate(startText);
}
TwoClass:TwoClass { *oneClass = new OneClass; }
}
and in qml to get the result
MyClass.result
or in the old fashioned way for now it's just to forward the references to the classes into the property?
