由于emf,gef,ve,Eclipse可视化插件最多支持都eclectic3.2版本,现在使用受到了限制。
windowbuilder,也就是原来的SWT Designer。Google收购了Instantiations,把它的工具也重新免费发布了。
用过swt designer的人都知它是非常好用的swing/swt可视化开发工具,有了它,swing/swt也可以像visual studio一样拖拉控件写程序(虽然netbean也可以,不过没怎用),可惜是个收费产品,后来把改名为windowbuilder。不过Google把这个工具的开发公司Instantiations收购了,并把这个产品免费发布。Google收购Instantiations是为了给它的GWT设计开发工具,据说也是为了它的Anroid搞开发工具(......)。单击确定后,就可以在列表中看到相关的安装文件。点击next一路安装下去。
安装完成后,重启Eclipse,点击File→New→Project...
生成的代码也很干净
