	Hi Stoyo, i would like to get a new line ("\n") while im pressing alt + enter during inline editing. I tried to modify the key handlers in the beginEdit function, but inplaceTextArea.append("\n"); didn�t work. Do you have an idea? Thank you very much, Alex

	Hi Alex, Handle enterInplaceEditMode and call e.getEditControl().addKeyListener() to add this keyTyped handler: Code public void keyTyped(KeyEvent e) { if ((e.getModifiers() & KeyEvent.ALT_MASK) != 0 && e.getKeyChar() == '\n') { JTextArea textControl = (JTextArea)e.getComponent(); textControl.insert("\n", textControl.getCaretPosition()); } } I hope that helps, Stoyan

	Hi Stoyo, i don�t exactly understand where i have to implement the keyTyped handler. Perhaps i forgot to tell you, that i�m using jdiagram as an applet and i use jscript for interaction. Thanks, Alex

	Tough luck, you can't implement a Java listener from JavaScript AFAIK. You could instead do this from your own applet that inherits from DiagramApplet: Code diagram.addDiagramListener(new DiagramAdapter() { public void enterInplaceEditMode(InPlaceEditEvent e) { e.getEditControl().addKeyListener(new KeyAdapter() { public void keyTyped(KeyEvent e) { if ((e.getModifiers() & KeyEvent.ALT_MASK) != 0 && e.getKeyChar() == '\n') { JTextArea textControl = (JTextArea)e.getComponent(); textControl.insert("\n", textControl.getCaretPosition()); } } }); } }); Or otherwise set InplaceEditAcceptOnEnter to false and the user will be able to use the Enter key for new lines, and end the edit operation with a click outside the text control. I hope that helps, Stoyan

	Hi Stoyo, thank you for the answers. I don�t know if it�s clear what i would like to implement: I don�t want to change anything from javascript. I would like to add a keylistener directly in the java applet. I hoped to solve this within beginEdit() in the DiagramView class. I don�t really understand what the addKeyListener function within beginEdit() does affect at all? Thank you, Alex

	The sample code above is what you need then. When you call beginEdit(), that should raise the enterInplaceEditMode event, which you can handle as shown above. That's the only way to get access to the JTextArea used for inplace editing.

	If you mean you have the source code and are directly modifying the beginEdit method, then copy the keyTyped function to the block after this line - inplaceTextArea.addKeyListener(new KeyAdapter(){

	Ahhhhg... i did it exactly as you recommended before i asked you here in the forum... It didn�t work because the jar builder didn�t work. That was the reason that i had no effect in the jdiagram.jar. Thanks!
