如何在IWorkbenchPage中设置活动页面

Question

I am running an application as Eclipse application where some operation is getting performed on a file and correspondingly other file is modified

I am getting the file like this :

    Display.getDefault().syncExec(new Runnable() {  
        @Override
        public void run() {
            IWorkbench workbench = PlatformUI.getWorkbench();
            IWorkbenchWindow workbenchWindow = workbench.getActiveWorkbenchWindow();
            IWorkbenchPage activePage = workbenchWindow.getActivePage();
            IEditorPart editor = activePage.getActiveEditor();
            IEditorInput input = editor.getEditorInput();
            IPath path = ((FileEditorInput)input).getPath();
}
}});

I am performing some operation on different file based on some input, and i want to set that as active page in running eclipse application.

I am not able to figure out how to set that active page.

I went through question but have not found exact question.

There is only one page in a workbench window. Editors are all on the same page.

For a file in the workspace you use IFile to reference the file.

There are lots of ways to get the IFile , for example if you have the path relative to the workspace root use:

IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
IFile file = root.getFile(new Path("path relative to workspace root"));

If you have an absolute path File you can use:

IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
URI location = file.toURI();
IFile[] files = root.findFilesForLocationURI(location);

Once you have the IFile you can open the default editor for the file using:

IDE.openEditor(activePage, file);

or you can specify a specific editor id with:

IDE.openEditor(activePage, file, "the editor id");

IDE is org.eclipse.ui.ide.IDE
