EditorStateListener

It is possible for an application which uses the JEditor to listen to the modifications of the underlying document by JEditor.addEditorStateListener(EditorStateListener):

• The listener will be fired by EditorStateListener.STATE_CREATED when the content of the JEditor is first set
• It will be fired by EditorStateListener.STATE_MODIFIED when the content of the document is modified
• It will be fired by EditorStateListener.STATE_UNCHANGED when the content of the document goes unchanged
• It will be fired by EditorStateListener.STATE_SAVED when the user asks to save the document (by typing CTRL+S). Note that the JEditor itself will do nothing upon typing CTRL+S, it is the responsability of the client application to process the save (or do nothing if it does not want to handle CTRL+S typing). See also supporting the CTRL+S key for more information

The state of modification can be modified by edits, but also copy / paste or undo / redo actions.

Supporting the CTRL+S key

The JEditor itself will do nothing upon typing CTRL+S, it is the responsability of the client application to process the save (or do nothing if it does not want to handle CTRL+S typing. You can do that by llistening to the EditorStateListener.STATE_SAVED event state. For example:

   JEditor editor = new JEditor();
   editor.setText(<the text>);
   editor.addEditorStateListener(new EditorStateListener() {
      public void documentStateChanged(short state) {
        if (state == EditorStateListener.STATE_SAVED) {
          try {
            editor.saveAs(file);
          } catch (IOException ex) {
          }
        }
      }
   });
