Мы переходим на Java 11, и в ходе курса нам нужно изменить несколько устаревших кодов.Внешний интерфейс нашего приложения в основном на Swing.Я не очень полезен для этого, поэтому мне нужна помощь / ввод.
В нашем старом коде мы настроили наш LookAndFeel API, напрямую расширив его до внутреннего API Java WindowsLookAndFeel.Я попытался решить эту проблему, добавив следующие строки в сценарий сборки:
-add-exports java.desktop/com.sun.java.swing.plaf.windows=ALL-UNNAMED
Но есть несколько проблем, с которыми мы сталкиваемся во время его работы, связанных с пользовательским интерфейсом.
Чтобы полностью решить эту проблемудля будущего выпуска мы планируем использовать MetalLookAndFeel API.Он работает отлично, но единственная проблема, с которой я сталкиваюсь, связана с обновлением.
Действие не сразу отражается.Допустим, я щелкаю некоторые из вкладок, а затем, чтобы увидеть их, мне нужно свернуть / щелкнуть другую вкладку.
Просто хотел узнать, что я что-то упускаю.
