Hi
As long as you dont do multiple inheritance ,
i think you base class design should work just fine.
However, make sure to overrride
int QGraphicsItem::type() const pr concrete class to make sure
qgraphicsitem_cast() works.

@steveq Thanks so much! Were u able to figure out how to make URLs, sandwiched between other text, clickable? e.g. if message was:

Hey, checkout this website: http://forum.qt.io, its really cool!

In that only the url should be click, and maybe show hover effect as well. I read some suggestions about using mouse hit-testing to achieve that, but it seems like a lot of work.

Another thing I really wanted to do was to make text selectable, but even that seems complicated.

@Fred-Waltzer MyQMLObject will be available in all the QML files of the project. So no need to create different C++ variable.
