Hi,

sorry i have trouble with my own QDoubleValidator, i set a Range 5-25 but i can't type 15 in to the QLineEdit:
myLineEdit->setValidator(new MyDoubleValidator( 5, 25, 2, myLineEdit));

Can anybody help me?

Greetings,

Qt Code: 
  1. class MyDoubleValidator : public QDoubleValidator
  2. {
  3. public:
  4. 	MyDoubleValidator( double bottom, double top, int decimals, QObject* parent = 0)
  5. 		: QDoubleValidator( bottom, top, decimals, parent){}
  6.  
  7. 	QValidator::State validate(QString & input, int &) const
  8. 	{
  9. 		const double b = bottom();
  10. 		const double t = top();
  11. 		const int d = decimals();
  12.  
  13. 		QRegExp empty(QString::fromLatin1("-?\\.?"));
  14. 		if (input.contains(' '))
  15. 			return Invalid;
  16. 		if (b >= 0 && input.startsWith(QLatin1Char('-')))
  17. 			return Invalid;
  18. 		if (empty.exactMatch(input))
  19. 			return Intermediate;
  20.  
  21. 		bool ok = false;
  22. 		double entered = input.toDouble(&ok);
  23. 		if (!ok) return Invalid;
  24.  
  25. 		int nume = input.count('e', Qt::CaseInsensitive);
  26.  
  27. 		int i; 
  28. 		if (input.contains(','))
  29. 			i = input.indexOf(',');
  30. 		else
  31. 			i = input.indexOf('.');
  32.  
  33. 		if (i >= 0 && nume == 0) {
  34. 			i++;
  35. 			int j = i;
  36. 			while(input[j].isDigit())
  37. 				j++;
  38. 			if (j - i > d)
  39. 				return Invalid;
  40. 		}
  41.  
  42. 		if (entered < b || entered > t)
  43. 			return Invalid;
  44.  
  45. 		return Acceptable;			
  46. 	}
  47. };
