FAQ How do I open an editor programmatically?

First of all, this works on eclipse 3.3.0. I haven't tried the codes on the other versions of eclipse.

            import java.io.File;

            import org.eclipse.core.filesystem.EFS;
            import org.eclipse.core.filesystem.IFileStore;

            import org.eclipse.ui.PartInitException;
            import org.eclipse.ui.IWorkbenchPage;
            import org.eclipse.ui.PlatformUI;
            import org.eclipse.ui.ide.IDE;




            File fileToOpen = new File( textField.getText() );

            if ( fileToOpen.exists() && fileToOpen.isFile() )
            {
                IFileStore fileStore = EFS.getLocalFileSystem().getStore( fileToOpen.toURI() );

                IWorkbenchPage page = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
                try
                {
                    IDE.openEditorOnFileStore( page, fileStore );

                }
                catch ( PartInitException e )
                {
                    //Create your error handler codes here
                }
            }
            else
            {
                //You may do something if the file is not a file and the file does not exist
            }
