Using same C++ object in multiple qml file

[aktarjahan2003]

I need to use same C++ object as type in several QML files.

in C++ main I have
qmlRegisterType<ConnectionNotifier>("MyConnectionNotifier", 1, 0, "ConnectionNotifier");

In qml I have
import MyConnectionNotifier 1.0
...
ConnectionNotifier
{
id: myBtConnotifier
}

If I do it in several qml file then it will create many C++ objects that I don't like. Can I pass my own element some how to other qml file that can use it?

Any other options?

hmmm if you make your c++ object a contextProperty in QML than you can use it any number of QML files. Please see the following code to understand what i want to say:

MyCplusplusClass m_MyCplusplusObject;
declartiveView->rootContext()->setContextProperty("cplusplusobject",&m_MyCplusplusObject);

now use cplusplusobject in any of the QML files.

Hi,

Please check this link , especially the Receiving signals part, it explains how signals in qml can be caught in c++ and also the same viceversa..
