Hi Sharad,
I got the same problem when trying to open an editor input. I had a File
selector customized to my file extension but I did not found any way to
create the EditorInput.
Finally I intercepted the filename and then created a IFileStore with
this pieces of code. I hope this will help you to open the file.
Best regards.
-- This is to open the file dialog and get the filename
public static String openDialog(IWorkbenchWindow window) {
// TODO Save locally the previous scenery just in case of errors.
// TODO Check is an scenery is already open. If so ask for closing.
// - Get the user to choose an scenery file.
// String sceneryPath = null;
final FileDialog fileChooser = new FileDialog(window.getShell(),
SWT.OPEN);
// TODO Configure the text of the dialog to be presented to the user.
fileChooser.setText("Texto to be configured.");
fileChooser.setFilterPath(null);
fileChooser.setFilterExtensions(OPEN_FILTER_EXTENSIONS);
fileChooser.setFilterNames(OPEN_FILTER_NAMES);
final String sceneryName = fileChooser.open();
return sceneryName;
}
-- This is to check the filename and to create the FileInput that is
required by the call to the IDE workbench with this call:
IDE.openEditorOnFileStore(page, newScenery.getFileStoreModel());
public static boolean checkFileStore(String sceneryName) throws
PartInitException {
if (null == sceneryName) return false;
newScenery = new Scenery();
newScenery.setSceneryName(sceneryName);
// - Check that the file selected exists and is valid.
final IFileStore fileStore = EFS.getLocalFileSystem().getStore(new
Path(sceneryName));
if (!fileStore.fetchInfo().isDirectory() &&
fileStore.fetchInfo().exists()) {
// - Read the scenery properties and locate the scenery object data.
final File sceneryFile = new File(sceneryName);
if (null == sceneryFile)
throw new PartInitException("The scenery file selected cannot
be open or is empty.");
final Properties props = new Properties();
try {
props.load(new BufferedInputStream(new
FileInputStream(sceneryFile)));
newScenery.setProperties(props);
final String modelFileName = props.getProperty("modelLocation");
if (null == modelFileName)
throw new PartInitException("The scenery model data file
selected cannot be open or is empty.");
newScenery.setModelFileName(modelFileName);
// - Test if the model exists and then open through the interface.
final IFileStore fileStoreModel =
EFS.getLocalFileSystem().getStore(new Path(modelFileName));
if (!fileStoreModel.fetchInfo().isDirectory() &&
fileStoreModel.fetchInfo().exists()) {
newScenery.setFileStore(fileStoreModel);
newScenery.setLoadStatus(Scenery.PREPARED);
return true;
}
} catch (final FileNotFoundException e) {
// EXCEPTION PartInitException("The scenery file open has
failed.");
// throw new PartInitException("The scenery file open has
failed." + e.getMessage());
e.printStackTrace();
throw new PartInitException("The scenery model data file cannot
be found.");
} catch (final IOException e) {
// EXCEPTION PartInitException("The scenery file open has
failed.");
// throw new PartInitException("The scenery file open has
failed." + e.getMessage());
e.printStackTrace();
throw new PartInitException("The scenery model data file cannot
be read or open.");
}
}
return false;
