Member Data Documentation

QCache<QString, const QPixmap> DtBMPDrawer::myCache [mutable, protected]

Mutable since cache is for optimization purposes only.

Conceptually there should be no difference in const between the first and second time a symbol is drawn.

QCache<QString, const QPixmap> DtBMPDrawer::myHighlightCache [mutable, protected]
