Eclipse RCP：如何注册一个ISourceProviderListener [英] Eclipse RCP: how to register an ISourceProviderListener

问题描述

今天我尝试了以下内容：

我有：

• a使用表单查看（ FormView ）


• a AbstractSourceProvider （提供者）将 FormView 中的更改提交给提供者之外的


• 一个View（ ConsumerView ） >它实现 ISourceProviderListener

FormView 更新提供者，它触发 fireSourceChanged 。但是，如何注册 ConsumerView ，以便它监听提供者中的更改？

这里的答案stackoverflow，没有真正解释如何做：
如何在Eclipse RCP中的视图之间进行通信？

另外Lars Vogels有关RCP命令的教程也经常被提及，但是我从那里得不到。感谢您的帮助！

解决方案

从您的 > ConsumerView createPartControl（..）方法：

  ISourceProviderService service =（ISourceProviderService）getSite（）。getService（ISourceProviderService.class）; 
 
 ISourceProvider yourProvider = service.getSourceProvider（yourSourceProviderName）; 
 
 yourProvider.addSourceProviderListener（this）; 
  

today i tried the following:

I have:

• a View with a form (FormView)
• a AbstractSourceProvider (Provider) to provide changes in FormView to the world
• a View (ConsumerView) that should consume information from Provider it implements ISourceProviderListener

FormView updates the Provider, which fires the fireSourceChanged. But how can I register the ConsumerView so that it listens for changes in the Provider?

This answer here on stackoverflow, did not really explain how to do it: How to communicate between views in Eclipse RCP?

Also Lars Vogels tutorials on RCP Commands are mentioned frequently, but I don't get it from there.

Thanks for your help in advance!

解决方案

From within your ConsumerView createPartControl(..) method:

ISourceProviderService service = (ISourceProviderService)getSite().getService(ISourceProviderService.class);

ISourceProvider yourProvider = service.getSourceProvider("yourSourceProviderName");

yourProvider.addSourceProviderListener(this);
