Hello

did you tried to put

scoreUI.setTune(tune);

before x = ... and y = ... ?

you can also use scoreUI.getElementAt(Point)

I writed an example with that on the group, on a click event on the score, you can get the point (position of the click) then see if there is an element at this point.

Hi, I am new to abc4j,
What I want to do with it is to render some notes using the library
and then draw something extra.
e.g. I want to circle a note that is wrongly played.
 
I think I first need to get the positions of the notes rendered.
I have read the article here: http://groups.google.com/group/abc4j/browse_thread/thread/2289cd2b603d4cd6
But I do not fully understand it. May you give me a more complete
example?
 
I really appreciate your help.
 
In the following code, I tried to get the (x,y) coordinates of a
particular note so that I can do something on it.
But it seems it is not the correct way of doing it.
 
public static void main(String[] args) {
 
Tune tune = new Tune();
Tune.Music music = tune.getMusic();
Note aNote = new Note(Note.F);
 
music.addElement(aNote);
 
JScoreComponent scoreUI =new JScoreComponent();
 
double x =
scoreUI.getRenditionElementFor(aNote).getBoundingBox().getX();
double y =
scoreUI.getRenditionElementFor(aNote).getBoundingBox().getY();
 
scoreUI.setTune(tune);
JFrame j = new JFrame();
j.add(scoreUI);
j.pack();
j.setVisible(true);
}
