Detailed Description

The QGalleryUnionFilter class provides a filter which matches the union of two or more meta-data filters.

A union filter represents the union of a list of gallery filters. Filters can be added to an union using either the append(), prepend(), or insert() functions, or using the << operator.

Union filters can also combining two gallery filters with the && operator.

This function was introduced in Qt Mobility 1.1.

QList<QGalleryFilter> QGalleryUnionFilter::filters () const

Returns the filters contained in a union.

This function was introduced in Qt Mobility 1.1.

void QGalleryUnionFilter::insert ( int index, const QGalleryMetaDataFilter & filter )
