How to connect button to function from other class?

Hi, what am I missing?

I don't know how to connect function from class Baza to QPushButton in .cpp ui file.
EncryptFile.h

class EncryptFile : public QMainWindow
{
	Q_OBJECT

public:
	EncryptFile(QWidget *parent = Q_NULLPTR);

private:
	Ui::EncryptFileClass ui;

private slots:
	void run();
};

Part EncryptFile.cpp

EncryptFile::EncryptFile(QWidget *parent)
	: QMainWindow(parent)
{
	ui.setupUi(this);
	Baza *plik = new Baza();
	connect(ui.createBtn, &QPushButton::clicked, this, &EncryptFile::run);
	connect(ui.bazaBtn, &QPushButton::clicked, this, &Baza::createDatabase);
}

Baza.h

class Baza : public QMainWindow 
{
	Q_OBJECT
private:
	sqlite3 *database;
	char *errMsg = 0;
	int rc;
public:
	Baza(QWidget *parent = Q_NULLPTR) {};
	~Baza() {};
	
public slots:
	void createDatabase();
};

First connect works. But another connect spit out: E0304, C2664, C3867.

Any ideas? Thanks :)

Hi,

Because you are using "this" as target which does not contain the method since it's not the same classe.

On a side note, Qt has a SQL module so you don't have to use SQLite directly.
