## Detailed Description

A RegExpFilter is a RoleFilter that accepts rows matching a regular rexpression.

In the following example, only rows with their `lastName` role beggining with the content of textfield the will be accepted:

    TextField {
       id: nameTextField
    }

    SortFilterProxyModel {
       sourceModel: contactModel
       filters: RegExpFilter {
           roleName: "lastName"
           pattern: "^" + nameTextField.displayText
       }
    }

## Property Documentation

caseSensitivity : Qt::CaseSensitivity

This property holds the caseSensitivity of the filter.

enabled : bool

This property holds whether the filter is enabled. A disabled filter will accept every rows unconditionally (even if it's inverted).

By default, filters are enabled.

inverted : bool

This property holds whether the filter is inverted. When a filter is inverted, a row normally accepted would be rejected, and vice-versa.

By default, filters are not inverted.

pattern : bool

The pattern used to filter the contents of the source model.

See also syntax.

roleName : string

This property holds the role name that the filter is using to query the source model's data when filtering items.

syntax : enum

The pattern used to filter the contents of the source model.

Only the source model's value having their RoleFilter::roleName data matching this pattern with the specified syntax will be kept.

Constant | Description
--- | ---
`RegExpFilter.RegExp` | A rich Perl-like pattern matching syntax. This is the default.
`RegExpFilter.Wildcard` | This provides a simple pattern matching syntax similar to that used by shells (command interpreters) for "file globbing".
`RegExpFilter.FixedString` | The pattern is a fixed string. This is equivalent to using the RegExp pattern on a string in which all metacharacters are escaped.
`RegExpFilter.RegExp2` | Like RegExp, but with greedy quantifiers.
`RegExpFilter.WildcardUnix` | This is similar to Wildcard but with the behavior of a Unix shell. The wildcard characters can be escaped with the character "".
`RegExpFilter.W3CXmlSchema11` | The pattern is a regular expression as defined by the W3C XML Schema 1.1 specification.
