## Properties

- bottom : int
- locale : string
- top : int

## Detailed Description

The IntValidator type provides a validator for integer values.

If no locale is set IntValidator uses the default locale to interpret the number and will accept locale specific digits, group separators, and positive and negative signs. In addition, IntValidator is always guaranteed to accept a number formatted according to the "C" locale.

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

     import QtQuick

     TextInput {
         focus: true
         validator: IntValidator {
             bottom: 0
             top: 100
         }
         onAcceptableInputChanged:
             color = acceptableInput ? "black" : "red";
     }
