Javafx中的倒计时
我目前正在尝试开发一个包含3个值的倒计时 第一个值是倒计时应该运行多长时间，第二个值是从倒计时变为橙色开始，第三个值是从倒计时变为红色开始。 我有一个问题，我的倒计时旋转，有时运行更快，当我恢复倒计时开始旋转！ 我有一个问题，如果我想最大化应用程序，我希望它自动放大场景中的所有对象。 用户界面是使用场景生成器构建的。 谢谢你的帮助Javafx中的倒计时,java,javafx,scenebuilder,Java,Javafx,Scenebuilder,我目前正在尝试开发一个包含3个值的倒计时 第一个值是倒计时应该运行多长时间，第二个值是从倒计时变为橙色开始，第三个值是从倒计时变为红色开始。 我有一个问题，我的倒计时旋转，有时运行更快，当我恢复倒计时开始旋转！ 我有一个问题，如果我想最大化应用程序，我希望它自动放大场景中的所有对象。 用户界面是使用场景生成器构建的。 谢谢你的帮助 package application; import javafx.application.Application; import javafx.fxml.FXM
