插件项目中做一个弹出框通过类名包名新建Java类，就重构了下eclipse 新建Java向导类。
随便修改了下：
弹出代码：
CustomNewClassCreationWizard wizard = new CustomNewClassCreationWizard(); wizard.init(PlatformUI.getWorkbench(), wizard.getSelection()); wizard.setForcePreviousAndNextButtons(true); MyWizardDialog.createAndOpenDialog(Display.getDefault().getActiveShell(),wizard);这里的CustomNewClassCreateWizard重构了NewElementWizard。

对话框页面的内容，也是一个重构类

对比下NewTypeWizardPage就知道做了什么改变。
这里还想做一个操作，将接口实现一个指定的类，并且不可move。
找到这个类的
/*
* @see WizardPage#createControl
*/
public void createControl(Composite parent) {
这个方法，顾名思义，则是一个创建组件的地方
看到里面的 createSuperInterfacesControls(composite, nColumns);
这个方法，这就是如何创建父接口的地方啦。
跟进去..
