如何以编程方式刷新Eclipse视图或RSE文件子系统? [英] How to programmatically refresh an Eclipse view, or RSE file subsystem?

问题描述

如何以编程方式更新Eclipse视图?(我想这可能不需要特定于RSE吗?).

How can I programmatically update an Eclipse view? (I suppose this might not need to be specific to RSE?).

背景:我将远程系统资源管理器(RSE)用于Eclipse，通过执行远程操作来做一些事情通过SSH命令执行命令，该命令将在远程主机上创建新文件.我意识到，远程系统"视图中列出的SFTP文件不会自动更新以显示新创建的文件.

Background: I use Remote System Explorer (RSE) for Eclipse, do some stuff by executing remote commands via SSH, which creates new files on the remote host. I realized that the SFTP file listing in the Remote systems view does not automatically get updated to show the newly created file.

到目前为止，我已经设法获得了相关的观点，就像这样:

I have managed so far to get the relevant view, like so:

IWorkbench workbench = PlatformUI.getWorkbench();
IViewRegistry viewReg = workbench.getViewRegistry();
IViewDescriptor[] views = viewReg.getViews();
for (IViewDescriptor view : views) {
  String viewID = view.getId();
    System.out.println("View ID: " + viewID);
    if (viewID.equals("org.eclipse.rse.ui.view.systemView")) {
      // Do something with the view here
    }
}

...并且可能要执行RSE特定的操作，所以我尝试抓住RemoteFileSubSystem:

... and for possibly doing something RSE specific, I tried grabbing the RemoteFileSubSystem:

IRemoteFileSubSystem rfss = RemoteFileUtility.getFileSubSystem(HPCUtils.getApplication().getHPCHost());

...但是在ViewDescriptor对象或FileSubSystem中，我都没有找到刷新视图或文件子系统的任何方法.我错过了什么?

... but neither in the ViewDescriptor object, nor the FileSubSystem, I have found any way to refresh the view, or the file subsystem. What have I missed?

推荐答案

您是否要刷新构造的容器?IOW，您编写的扩展 org.eclipse.rse.core.subsystems.AbstractResource ?

Are you looking to refresh a container that you constructed? IOW, a class that you wrote that extends org.eclipse.rse.core.subsystems.AbstractResource?

如果是这样，请尝试以下代码...

If so, try this code ...

ISystemRegistry registry = SystemStartHere.getSystemRegistry();

SystemResourceChangeEvent event = new SystemResourceChangeEvent(this, 
    ISystemResourceChangeEvents.EVENT_REFRESH, yoursubsystem);

registry.fireEvent(event);

如果您不在自己的资源容器中，但是知道资源容器的对象，则将 SystemResourceChangeEvent 构造中的 this 替换为该对象.

If you're NOT inside your own resource container, but you know the resource container's object, replace this in the SystemResourceChangeEvent construction with the object.
