FAQ How do I open an editor programmatically?
Use the openEditor methods on org.eclipse.ui.IWorkbenchPage to open an editor on a given input. The openEditor methods require you to supply the ID of the editor to open. You can use the editor registry to find out what editor ID is appropriate for a given file name, using the getDefaultEditor method on IEditorRegistry. In Eclipse 3.0, the editor opening methods that were specific to IFile were moved to the IDE class.
IWorkbenchPage page = ...; IFile file = ...; IEditorDescriptor desc = PlatformUI.getWorkbench(). getEditorRegistry().getDefaultEditor(file.getName()); page.openEditor( new FileEditorInput(file), desc.getId());
