I defined my QObject-derived class with qmlRegisterType.
After that I try to use this type in JS code like this:
@if (obj instanceof MyQObject) ...@
and this didn't work.
There is an error during execution:
qrc:///qml/main.qml:19: TypeError: Type error
How can I use C++ type in JS code?
Did you import the type in main.qml? Eg:
import org.world.hello 1.0
How is obj defined? Is it null when the error occurs?
First of all, below shows how to instantiate your cpp objects in qml
import my.app.MyQObject 1.0
I thought Object.create will work, but no.
Second, in QML apparently your MyQObject, as well as other QML elements all have type of object.
it doesn't even have prototype.. so it behaves sortof like a builtin object
If you need reflection, check objectName property. Any exported QObject will have that property by default. This seems the case since Qt 5.0
So instead of typeof(obj), use obj["objectName"]
