When I place five objects of MTR::Button class on MyWidget object (simple testing area) using QVBoxLayout I receive five buttons on one pile!

How to achieve an ordinary vertical box layout effect in this case?

MTRButton.h:
Qt Code: 
  1. #ifndef MTR_Button_H
  2. #define MTR_Button_H
  3. #include <QAbstractButton>
  4. class QSize;
  6.  
  7. namespace MTR {
  8. class Button : public QAbstractButton {
  9. 	Q_OBJECT
  10. public:
  11. 	Button(QWidget *parent = 0);
  12. 	Button(QString tekst, QWidget *parent = 0);
  13. protected:
  14. 	void paintEvent(QPaintEvent *event);
  15. 	QSize sizeHint() const;
  16. 	QSize minimumSizeHint() const;
  17. 	void mouseMoveEvent(QMouseEvent *event);
  18. 	void mousePressEvent(QMouseEvent *event);
  19. 	void mouseReleaseEvent(QMouseEvent *event);
  20. private:
  21. 	bool hovered;
  22. 	QFont font;
  23. };
  24. }
  25. #endif

Five such objects are placed in a QVBoxLayout on MyWidget
MyWidget.h
Qt Code: 
  1. #ifndef TESTWIDGET
  2. #define TESTWIDGET
  3. #include <QWidget>
  4. namespace MTR {
  5. class Button;
  6. }
  7. class MyWidget : public QWidget {
  8. 	Q_OBJECT
  9. public:

  11. public slots:

  13. private:
