【问题描述】:
我使用 java 已经一年了,对 javaFX 还是很陌生,到目前为止,我一直在学习使用 scenebuilder 的基本教程。到目前为止,我已尝试将 translatetransition 应用于我的按钮,但它似乎根本没有移动。当我运行程序时,会显示带有背景的场景,但按钮只是停留在场景构建器中定义的起始位置并且不会移动。在检查了此站点上的其他类似问题后,我确保我实现了 Initializable 并在我的初始化函数之前添加了@Override,并且我确保我的转换已播放。我也在一个矩形上尝试过 translatetransition ,它不会移动。可能只是我使用的是eclipse而不是netbeans
