QT create a new class with an other in parameters

I m beginner in c++ with QT. I have a problem to instanciate a new class with an other in parameter..

My problem is to add in a QList Asteroids Object. In QT I have this error message:

cannot convert ‘SettingsAsteroid’ to ‘SettingsAsteroid*’ in assignment
this->settingsAsteroid = SettingsAsteroid();

I have show the .h and .c of the class who do it and the constructor of Asteroid.I think others class aren’t important.

Thx you to help a beginner in this language 🙂
