问题描述
我正在使用Eclipse-RCP插件。还有一个带有TreeViewer的插件，我想从插件中选择一个项目。我不知道如何访问它，甚至有可能吗？
I'm working at a Plugin for a Eclipse-RCP. There is another Plugin with a TreeViewer and I want to select an Item from my Plugin. I don't know how to get access it, is this even possible?
我认为可以通过以下方式获得正确的视图：
I think can get the correct view with:
IViewReference home;
IViewReference [] viewRefs = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().getViewReferences();
for (int i = 0; i < viewRefs.length; i++) {
if(viewRefs[i].getId()==myid){
home = viewRefs[i];
break;
}
}
但是家不是TreeViewer，我无法投射它。如何获得TreeViewer？
But home is not a TreeViewer and I cant cast it. How can I get the TreeViewer?
home.getTreeViewer() //Doesn't work cause of casting issues
我是rcp的新手，所以我很乐意提供一些解释。
I am a newbie to rcp, so I would be nice for some explanation.
推荐答案
您需要使用以下视图找到视图：
You need to find your view using:
IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
IViewPart viewPart = page.findView("your view id");
然后可以将视图部分转换为视图类，并调用在该类上编写的方法：
You can then cast the view part to your view class and call a method that you write on that class:
if (viewPart != null) {
MyViewClass myViewPart = (MyViewClass)viewPart;
myViewPart.getTreeViewer();
}
其中 MyViewClass 是您的 ViewPart 类。您将必须编写 getTreeViewer 方法。
where MyViewClass is your ViewPart class. You will have to write the getTreeViewer method.
如果视图当前未打开，则可以使用 showView ：
If the view is not currently open you can use showView:
viewPart = page.showView("your view id");
