Member Enumeration Documentation

◆ AdditionalRoles

enum Digikam::DCategorizedSortFilterProxyModel::AdditionalRoles

inherited

Enumerator
CategoryDisplayRole	NOTE: use printf "0x%08X\n" $(($RANDOM*$RANDOM)) to define additional roles. This role is used for asking the category to a given index
CategorySortRole	This role is used for sorting categories. You can return a string or a long long value. Strings will be sorted alphabetically while long long will be sorted by their value. Please note that this value won't be shown on the view, is only for sorting purposes. What will be shown as "Category" on the view will be asked with the role CategoryDisplayRole.

◆ compareCategories()

int Digikam::DCategorizedSortFilterProxyModel::compareCategories	(	const QModelIndex &	left,
		const QModelIndex &	right
	)		const

protectedvirtualinherited

This method compares the category of the left index with the category of the right index.

Internally and if not reimplemented, this method will ask for left and right models for role CategorySortRole. In order to correctly sort categories, the data() method of the model should return a qlonglong (or numeric) value, or a QString object. QString objects will be sorted with QString::localeAwareCompare if sortCategoriesByNaturalComparison() is true.

Note: Please have present that: QString(QChar(QChar::ObjectReplacementCharacter)) > QString(QChar(QChar::ReplacementCharacter)) > [ all possible strings ] > QString();

This means that QString() will be sorted the first one, while QString(QChar(QChar::ObjectReplacementCharacter)) and QString(QChar(QChar::ReplacementCharacter)) will be sorted in last position.

Warning: Please note that data() method of the model should return always information of the same type. If you return a QString for an index, you should return always QStrings for all indexes for role CategorySortRole in order to correctly sort categories. You can't mix by returning a QString for one index, and a qlonglong for other.

Note: If you need a more complex layout, you will have to reimplement this method.

Returns: A negative value if the category of left should be placed before the category of right. 0 if left and right are on the same category, and a positive value if the category of left should be placed after the category of right.

Reimplemented in Digikam::ImportFilterModel, ShowFoto::ShowfotoFilterModel, and Digikam::ItemFilterModel.

◆ lessThan()

bool Digikam::DCategorizedSortFilterProxyModel::lessThan	(	const QModelIndex &	left,
		const QModelIndex &	right
	)		const

overrideprotectedinherited

Overridden from QSortFilterProxyModel. If you are subclassing DCategorizedSortFilterProxyModel, you will probably not need to reimplement this method.

It calls compareCategories() to sort by category. If the both items are in the same category (i.e. compareCategories returns 0), then subSortLessThan is called.

Returns: Returns true if the item left is less than the item right when sorting.

Warning: You usually won't need to reimplement this method when subclassing from DCategorizedSortFilterProxyModel.
