SWT内嵌浏览器Browser对象使用JQuery等Web插件

由 ▼魔方 西西 提交于 2020-03-01 21:19:47
前言 我们知道web 的UI界面真得很漂亮，而且开源社区有很多插件可以用，所以要开发出漂亮的页面也很容易。那么，我们使用SWT/JFace进行桌面软件的开发时，也想要实现一些像JQuery EasyUI等等漂亮的表格，可以说是非常难。但是，SWT Browser 是 Eclipse SWT 的标准部件，它提供了把 HTML 整合到 Java 平台的能力。该部件植入了平台流行的 HTML 渲染引擎：在 Microsoft Windows 平台上是 IE，在 Linux 平台上是 Mozilla，在 Apple Mac 平台上是 Safari。但在实现的过程中还是有很多很坑的，笔者在网上搜了很多资料，都太简略，没什么干货。所以，只能自己摸索。废话不多说，我们直接干吧！ 一. 创建简单的浏览器 import org.eclipse.swt.*; import org.eclipse.swt.browser.*; import org.eclipse.swt.layout.*; import org.eclipse.swt.widgets.*; public class SimpleBrowser { public static void main(String [] args) { Display display = new Display(); final Shell shell =
