#macos #какао #nsscroller #macos-темный режим
Вопрос:
Я использую NSScroller в приложении cocoa. NSScroller полупрозрачен в темном режиме mojave, но отлично смотрится в светлом режиме mojave.
Я попытался создать подкласс nsscroller и попытаться изменить цвет фона. он изменяет цвет фона, но эффект полупрозрачности не исчезает.
class CustomScroller: NSScroller {
- (void)drawRect:(NSRect)dirtyRect {
NSColor.red.set()
__NSRectFill(dirtyRect)
self.drawKnob()
}
}
Комментарии:
1. прочитайте все комментарии «draw», которые можно найти в NSScroller.h
Ответ №1:
Может быть, добавить это в свой пользовательский скроллер?
- (BOOL) isOpaque {return YES;}
Почтенный BGHUDAppKit предоставляет пример того, как создавать собственные темы с нуля.
Большинство людей ненавидят это, потому что это недостижимый беспорядок.
Несмотря на это, я годами поддерживал свою собственную версию в актуальном состоянии 🙂
Вам понадобится ваша собственная реализация «темы». Например [[[self theme] scrollerStroke] set]; , необходимо вернуть NSColor . Хорошее эмпирическое правило для тем пользовательского интерфейса:
- правило 10% Человеческий глаз может легко различить разницу в яркости в 10%, поэтому, например, полоса прокрутки должна быть выделена цветом, который на 10% ярче цвета заливки. ( контур 57.0 / 255.0, заливка 50.0 / 255.0)
- старайтесь использовать оттенки серого как можно чаще.
Вот моя реализация с включенными примечаниями для различных версий ОС:
