javafx做桌面应用程序

标签:primary collect style prim ring version str system lis idea可以直接开发javafx项目,但是需要一个SceneBuilder ,用来开发ui,或者按照 https://blog.csdn.net/hst_gogogo/article/details/82530929 ,进行集成 开发过程 说明:给fxml文件内标签设置control配置我这边没有生效,通过id注解控件,拿到的控件为空;通过 #方法名 注解控件方法是可以成功调用到方法 这边我用的是仿照安卓的控件查找和事件设置 java代码:、 Main.java MainControl.java fxml布局,是通过SceneBuilder绘制UI后,保存的fxml文件 javafx做桌面应用程序 标签:primary collect style prim ring version str system lis 原文地址:https://www.cnblogs.com/fengchuxiaodai/p/13353882.htmlpackage sample;
