Может быть, добавить это в свой CustomScroller?
- (BOOL) isOpaque {return YES;}
Достопочтенный BGHUDAppKit предоставляет пример того, как рисовать свои собственные темы с нуля.
Большинство людей ненавидят это, потому что это неразрешимый беспорядок.Несмотря на это, я постоянно обновляю свою собственную версию годами:)
Вам понадобится ваша собственная реализация 'theme'.Например, [[[self theme] scrollerStroke] set]; необходимо вернуть NSColor.Хорошее эмпирическое правило для тем пользовательского интерфейса:
правило 10% Человеческий глаз может легко отличить разницу яркости в 10%,например, полоса прокрутки должна быть выделена цветом, который на 10% ярче, чем цвет заливки.(обведите 57.0 / 255.0, заполните 50.0 / 255.0)
попытайтесь использовать цвета в оттенках серого в максимально возможной степени.
Вот моя реализацияс примечаниями для различных версий ОС:
