Hi,

This mornig I tried to add a custom widget of mine into a dialog form and each time it makes qt designer close. I don't know why.

My widget is quite simple and is composed of 5 bitmaps.

Here is the code of the .h of my widget
Qt Code: 
  1. #ifndef _HMI_ITEM_SOUND_TESTER_H
  2. #define _HMI_ITEM_SOUND_TESTER_H
  3.  
  4. #include <qwidget.h>
  5.  
  6. class CHmiItemSound;
  7. class QLabel;
  8.  
  9. class CHmiItemSoundTester : public QWidget
  10. {
  11. 	// Constructor / Desctuctor
  12. public:
  13. 	CHmiItemSoundTester(QWidget* parent=0, const char* name=0);
  14.  
  15. 	// Functions
  16. 	void updateItem(const CHmiItemSound&);
  17. 	void showItem();
  18. 	void hideItem();
  19. 	void testItem();
  20.  
  21. 	// Members
  22. private:
  23. 	CHmiItemSound* itemSound;
  24.  
  25. 	QLabel* car;
  26. 	QLabel* hpAvGa;
  27. 	QLabel* hpAvDr;
  28. 	QLabel* hpArGa;
  29. 	QLabel* hpArDr;
  30. };
  31.  
  32. #endif
