52 -

53 The IntValidator type provides a validator for integer values. -

54 -

55 If no \l locale is set IntValidator uses the \l {QLocale::setDefault()}{default locale} to -

56 interpret the number and will accept locale specific digits, group separators, and positive -

57 and negative signs. In addition, IntValidator is always guaranteed to accept a number -

58 formatted according to the "C" locale. -

114 \brief Defines a validator for non-integer numbers. -

115 -

116 The DoubleValidator type provides a validator for non-integer numbers. -

117 -

118 Input is accepted if it contains a double that is within the valid range -

119 and is in the correct format. -

120 -

121 Input is accepected but invalid if it contains a double that is outside -

122 the range or is in the wrong format; e.g. with too many digits after the -

123 decimal point or is empty. -

124 -

125 Input is rejected if it is not a double. -

126 -

127 Note: If the valid range consists of just positive doubles (e.g. 0.0 to -

128 100.0) and input is a negative double then it is rejected. If \l notation -

129 is set to DoubleValidator.StandardNotation, and the input contains more -

130 digits before the decimal point than a double in the valid range may have, -

131 it is also rejected. If \l notation is DoubleValidator.ScientificNotation, -

132 and the input is not in the valid range, it is accecpted but invalid. The -

133 value may yet become valid by changing the exponent. -
