How to close an editor programatically in eclipse

Question

We want to close all opened files of a project (IProject) in eclipse when we delete it. I can reach IFiles via members method of a project. I want to close deleted project's all files.

Answer 1

You can get references to the open editors on a page with:

IWorkbenchWindow workbenchWindow = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
IWorkbenchPage page = workbenchWindow.getActivePage();

IEditorReference[] editorRefs = page.getEditorReferences();

Get the actual editor part from the references with:

IEditorPart editor = editorRefs[index].getEditor(true);

Get the editor input:

IEditorInput input = editor.getEditorInput();

Get the file the editor is editing:

IFile file = (IFile)input.getAdapter(IFile.class);

Close an editor:

page.closeEditor(editor, true);
