}

error2: expected '{' before '}' token

error3: expected unqualified-id before '}' token

Down here is my code.

#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include <mainwindow.h>


#include <QFileDialog>
#include <QLabel>

namespace Ui
{
class Mainwindow:
}

public QMainWindow:

{
Q_OBJECT

public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();

protected:
void changeEvent (QEvent *e);

private slots:
void on_pushButton_clicked();

private:
Ui::MainWindow *ui;
}

#endif // MAINWINDOW_H

A derived class is usually written:

class Foo : public Bar
{
};

You have written:

public Bar :
{
}

Please Keskiverto thank you so much, but i'm just learning alone on ground, can you just correct my entire code please?

Thank you.

If you're learning alone then you'll gain much more understanding correcting your own code. :-)
