Member Function Documentation

compare()

int ShowFoto::ShowfotoItemSortSettings::compare	(	const ShowfotoItemInfo &	left,
		const ShowfotoItemInfo &	right ) const

Return -1 if left is less than right, 1 if left is greater than right, and 0 if left equals right comparing the current sort role's value. Adheres to set sort role and sort order.

compareCategories()

int ShowFoto::ShowfotoItemSortSettings::compareCategories	(	const ShowfotoItemInfo &	left,
		const ShowfotoItemInfo &	right ) const

It returns -1 if the left ShowfotoItemInfo is less than right, and 0 if both fall in the same category, and 1 if the left ShowfotoItemInfo is greater than right. Adheres to set categorization mode and current category sort order.

lessThan() [1/2]

bool ShowFoto::ShowfotoItemSortSettings::lessThan	(	const QVariant &	left,
		const QVariant &	right ) const

Adheres to current sort role and sort order.

lessThan() [2/2]

bool ShowFoto::ShowfotoItemSortSettings::lessThan	(	const ShowfotoItemInfo &	left,
		const ShowfotoItemInfo &	right ) const

Adheres to current sort role and sort order.
