Member Function Documentation

◆ cacheCategory()

const QRect & Digikam::DCategorizedView::Private::cacheCategory ( const QString &  category)

Caches and returns the rect that corresponds to category

We're sure categoriesPosition doesn't contain category

◆ cachedRectCategory()

const QRect & Digikam::DCategorizedView::Private::cachedRectCategory ( const QString &  category)

Returns the rect that corresponds to category

Note
If the rect is not cached, it becomes cached

◆ cachedRectIndex()

const QRect & Digikam::DCategorizedView::Private::cachedRectIndex ( const QModelIndex &  index)

Returns the rect that corresponds to index

Note
If the rect is not cached, it becomes cached

Referenced by Digikam::DCategorizedView::setSelection().

◆ cacheIndex()

const QRect & Digikam::DCategorizedView::Private::cacheIndex ( const QModelIndex &  index)

Caches and returns the rect that corresponds to index

We're sure elementsPosition doesn't contain index

◆ categoryUpperBound()

int Digikam::DCategorizedView::Private::categoryUpperBound ( SparseModelIndexVector &  modelIndexList,
int  begin,
int  averageSize = 0 
)

This method will, starting from the index at begin in the given (sorted) modelIndex List, find the last index having the same category as the index to begin with.
