Detailed Description

The QGalleryProperty class provides a string constant identifying a gallery property.

QAbstractGallery implementations use to QGalleryProperty to define the names of properties in their schemas. In addition to providing the name of a property QGalleryProperty also contains a number of operator overloads and functions for constructing meta-data filters.

See also QGalleryType and QGalleryMetaDataFilter.

Member Type Documentation

enum QGalleryProperty::Attribute
flags QGalleryProperty::Attributes

This enumeration describes the attributes of a property.

Constant	Value	Description
`QGalleryProperty::CanRead`	`0x01`	The value of this property can be read.
`QGalleryProperty::CanWrite`	`0x02`	The value of this property can be written.
`QGalleryProperty::CanSort`	`0x04`	The value of this property can be used to sort items.
`QGalleryProperty::CanFilter`	`0x08`	The value of this property can be used in a filter.

The Attributes type is a typedef for QFlags<Attribute>. It stores an OR combination of Attribute values.

Member Function Documentation

QString QGalleryProperty::ascending () const

Returns a sort key which indicating items should be sorted a property in ascending order.

QGalleryMetaDataFilter QGalleryProperty::contains ( const QString & string ) const

Returns a gallery filter which tests if a property value contains contains a string literal.

QString QGalleryProperty::descending () const

Returns a sort key which indicating items should be sorted a property in descending order.

QGalleryMetaDataFilter QGalleryProperty::endsWith ( const QString & string ) const

Returns a gallery filter which tests if a property value ends with a string literal.

QString QGalleryProperty::name () const

Returns the name of a property.

QGalleryMetaDataFilter QGalleryProperty::regExp ( const QString & regExp ) const

Returns a gallery filter which tests if a property value matches a regExp.

QGalleryMetaDataFilter QGalleryProperty::regExp ( const QRegExp & regExp ) const

Returns a gallery filter which tests if a property value matches a regExp.

QGalleryMetaDataFilter QGalleryProperty::startsWith ( const QString & string ) const

Returns a gallery filter which tests if a property value starts with a string literal.

QGalleryMetaDataFilter QGalleryProperty::wildcard ( const QString & string ) const

Returns a gallery filter which tests if a property value matches a string literal using wildcard matching.

QGalleryProperty::operator QString () const

Returns the name of a property.

QGalleryMetaDataFilter QGalleryProperty::operator< ( const QVariant & value ) const

Returns a gallery filter which tests if a property is less than a value.

QGalleryMetaDataFilter QGalleryProperty::operator<= ( const QVariant & value ) const

Returns a gallery filter which tests if a property is less than or equal to a value.

QGalleryMetaDataFilter QGalleryProperty::operator== ( const QVariant & value ) const

Returns a gallery filter which tests if a property is equal to a value.

QGalleryMetaDataFilter QGalleryProperty::operator> ( const QVariant & value ) const

Returns a gallery filter which tests if a property is greater than a value.

QGalleryMetaDataFilter QGalleryProperty::operator>= ( const QVariant & value ) const

Returns a gallery filter which tests if a property is greater than or equal to a value.
