Detailed Description

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

• Accepted Input: Input is accepted if it contains a double that is within the valid range and is in the correct format.
• Accepted but Invalid Input: Input is accepted but considered invalid if it contains a double that is outside the valid range or is in the wrong format (for example, too many digits after the decimal point or empty).
• Rejected Input: Input is rejected if it is not a double.

The following example shows a TextInput object with a DoubleValidator to check that the user has input a double within the specified range, updating the text color to highlight invalid input:

import QtQuick

TextInput {
    focus: true
    validator: DoubleValidator {
        bottom: 0.00
        top: 100.00
        decimals: 2
        notation: DoubleValidator.StandardNotation
    }
    onAcceptableInputChanged:
        color = acceptableInput ? "black" : "red";
}
