How to use QObject in derived class

[imaqt 0]

I have a MainWindow : public QMainWindow class that instanciates OtherClass : public QObject. I want OtherClass to have MainWindow as its parent, and only be able to be instantiated with a MainWindow. Here's the class I got but it doesn't compile:

class OtherClass : QObject{
OtherClass(Ui::MainWindow* parent) :QObject{parent} {}
}

MainWindow and Ui::MainWindow are two different classes. Ui::MainWindow is the generated ui class. It does not derive from QObject and so it can't be used as a parent for QObjects.

If you want MainWindow to be the parent then say so:

OtherClass(MainWindow* parent) : QObject{parent} {}

Thank you for the reply.
I used Ui::MainWindow, because it didn't recognize MainWindow. Turns out i had a circular dependency issue with the #include files.
