Detailed Description

Filter model for tags that can filter by tag property

Member Enumeration Documentation

◆ FilterBehavior

enum Digikam::AlbumFilterModel::FilterBehavior

inherited

Enumerator
SimpleFiltering	If an index does not matched, the index and all its children are filtered out. This is the Qt default behavior, but undesirable for album trees.
FullFiltering	Default behavior. If an index matches, it is shown, which directly means all its parents are shown as well. In addition, all its children are shown as well.
StrictFiltering	If an index matches, it is shown, which directly means all its parents are shown as well. Its children are not shown unless they also match.

◆ MatchResult

enum Digikam::AlbumFilterModel::MatchResult

inherited

Enumerator
NoMatch	This enum can be used as a boolean value if match/no match only is needed.
DirectMatch	The index itself is matched.
ParentMatch	A parent if the index is matched.
ChildMatch	A child of the index is matched.
SpecialMatch	The index is matched not because of search settings, but because it has a special type.

◆ matches()

bool Digikam::TagPropertiesFilterModel::matches ( Album * album ) const

overrideprotectedvirtual

This method provides the basic match checking algorithm. Return true if this single album matches the current criteria. This method can be overridden to provide custom filtering.

Parameters

album the album to tell if it matches the filter criteria or not.

Reimplemented from Digikam::CheckableAlbumFilterModel.

Reimplemented in Digikam::TagsManagerFilterModel.

◆ matchResult() [1/2]

AlbumFilterModel::MatchResult Digikam::AlbumFilterModel::matchResult ( Album * album ) const

protectedinherited

Returns if the filter matches this album (same logic as filterAcceptsRow). An album matches if the search text settings are found in a parent album's title, in the album's title or in a child album's title, or if it is a special album (root) that is never filtered out.

◆ matchResult() [2/2]

AlbumFilterModel::MatchResult Digikam::AlbumFilterModel::matchResult ( const QModelIndex & index ) const

inherited

Returns the MatchResult of an index of this model. Never returns NoMatch for a valid index, because in this case, the index would rather be filtered out.
