How can i build my class without conflict between QSqlTableModel and Q_OBJECT?
I'm trying to build next code, but compiler says:
"sqltablemodel.h:12: error: undefined reference to `vtable for
SqlTableModel'"
I understand that the QSqlTableModel already has Q_OBJECT before.
But after removing this macro, I can't call my function from QML.
The debugger says that: ajax is not a function.
How can i build my class without conflict between inheritance & macros?
//sqltablemodel.h
class SqlTableModel : public QSqlTableModel {
Q_OBJECT
public:
Q_INVOKABLE void ajax(){
qDebug() << "123";
}
}
//main.cpp
SqlTableModel *sqlTableModel = new SqlTableModel();
context->setContextProperty("sqlTableModel", sqlTableModel);
c++ qt qml

Q_OBJECTis not some class member that you can derive. It's instruction formocto generate additional class members for the specified class and to enable the meta object system. See here for more info. As for thevtableerror - you probably have to run qmake and rebuild the project after adding the macro.
