DoubleValidatorInherits QtObject DoubleValidator instantiates the C++ class QDoubleValidator PropertiesDetailed DescriptionThis element provides a validator for non-integer numbers. Input is accepted if it contains a double that is within the valid range and is in the correct format. Input is accepected but invalid if it contains a double that is outside the range or is in the wrong format; e.g. with too many digits after the decimal point or is empty. Input is rejected if it is not a double. Note: If the valid range consists of just positive doubles (e.g. 0.0 to 100.0) and input is a negative double then it is rejected. If notation is set to DoubleValidator.StandardNotation, and the input contains more digits before the decimal point than a double in the valid range may have, it is also rejected. If notation is DoubleValidator.ScientificNotation, and the input is not in the valid range, it is accecpted but invalid. The value may yet become valid by changing the exponent. Property DocumentationThis property holds the validator's minimum acceptable value. By default, this property contains a value of -infinity. This property holds the validator's maximum number of digits after the decimal point. By default, this property contains a value of 1000. This property holds the name of the locale used to interpret the number. See also QML:Qt::locale(). This property holds the notation of how a string can describe a number. The possible values for this property are:
If this property is set to DoubleValidator.ScientificNotation, the written number may have an exponent part (e.g. 1.5E-2). This property holds the validator's maximum acceptable value. By default, this property contains a value of infinity. |
