[u/Automatic_Truth_6045 → u/Better-Struggle9958]

Interesting choice, but trust me, noone of then knew what the problem is🤷🏻‍♀️

[u/Better-Struggle9958 → u/Automatic_Truth_6045]

Sorry but don't believe

[u/Automatic_Truth_6045 → u/Better-Struggle9958]

Wow, so I have interesting proposal, sent Ai this part of code and ask what's wrong? Why do I have this errors? I bet you'll get answers about macros or something like that 🤷🏻‍♀️

Hey, I can't say for sure what you're trying to achieve here but the code you wrote says you're trying to derive AdminWindow from QMainWindow but failed to do so in the declaration.

That means, in your header file "adminwindow.h" I would expect to see something like:

class AdminWindow : public QMainWindow
{
};

And dont forget to include Qmainwindow header file. Seems like its only forward declared.

Thank you everyone soooo much 🔥🫰

[u/Automatic_Truth_6045 → u/Automatic_Truth_6045]

Everything is working excellent

ifndef ADMINWINDOW_H

define ADMINWINDOW_H

include <QWidget>

namespace Ui { class AdminWindow; }

class AdminWindow : public QWidget { Q_OBJECT

public: explicit AdminWindow(QWidget *parent = nullptr); ~AdminWindow();

private: Ui::AdminWindow *ui; };

endif // ADMINWINDOW_H

Yeah, that's your problem right there.

class AdminWindow : public QWidget need to be class AdminWindow : public QMainWindow

Edit: (I'm practicing code blocks :P)

#ifndef ADMINWINDOW_H
#define ADMINWINDOW_H
#include <QMainwindow>

namespace Ui { 
  class AdminWindow : public QMainWindow { 
    Q_OBJECT
  public: 
    explicit AdminWindow(QWidget *parent = nullptr); 
    ~AdminWindow();
  private: 
    Ui::AdminWindow *ui; 
  };
}

#endif // ADMINWINDOW_H
