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.

ConstantDescription
RegExpFilter.RegExpA rich Perl-like pattern matching syntax. This is the default.
RegExpFilter.WildcardThis provides a simple pattern matching syntax similar to that used by shells (command interpreters) for "file globbing".
RegExpFilter.FixedStringThe pattern is a fixed string. This is equivalent to using the RegExp pattern on a string in which all metacharacters are escaped.
RegExpFilter.RegExp2Like RegExp, but with greedy quantifiers.
RegExpFilter.WildcardUnixThis is similar to Wildcard but with the behavior of a Unix shell. The wildcard characters can be escaped with the character "".
RegExpFilter.W3CXmlSchema11The pattern is a regular expression as defined by the W3C XML Schema 1.1 specification.
