pass ui to subclass

[phil333]

I would like to split up the code of my application into multiple classes, each class containing a dockwidget with its underlying functionality.

For that I would like to have access to the original "ui" from my mainclass, since the dockwidgets need to change functionality in the main window. How can I connect this?

I have managed to pass the "ui" to a function, but i cant figure out how to store it inside the new object.
Any other approaches to solve this problem are also welcome.

#ifndef SUBCLASS_H
#define SUBCLASS_H
#include <ui_mainclass.h>
 
namespace Ui {
class MainClass;
}
 
class SubClass
{
private:
    Ui::Ui_MainClass *ui;
public:
    DataGeneration(Ui_MainClass *myUi);
}

#ifndef SUBCLASS_H
#define SUBCLASS_H
#include <ui_mainclass.h>

namespace Ui {
class MainClass;
}

class SubClass
{
private:
    Ui::Ui_MainClass *ui;
public:
    DataGeneration(Ui_MainClass *myUi);
}

NewSubclass::NewSubclass( Ui_MainClass *myUi)
{
    qDebug() << myUi->tableWidget->rowCount(); // works
 
    ui = myUi // does not work
}

NewSubclass::NewSubclass( Ui_MainClass *myUi)
{
    qDebug() << myUi->tableWidget->rowCount(); // works

    ui = myUi // does not work
}
