Hello the forum,
I'm in the midst of writing a simple Animator, and I'm having listener problems. The following is a method that adds a "Frame" to the end of an "Animation". The class that this is in extends JPanel, and the Frame class for the moment extends JButton Implements MouseListener.
public void addFrame(Image i){
if(i != null){
Frame temp = new Frame(i,(length()+1)+"");
addMouseListener(temp);
add(temp);
System.out.println("width: "+temp.getImageWidth()+", height: "+temp.getImageHeight()+", "+length()+" frames total");
if (playhead_position < 0) {
playhead_position = 0;
}
}
}
Mouse events are not being heard by my "Frames". Now, these Frame(JButton) objects are nestled in the Animator(Jpanel) which is nestled within a JScrollPane which is inside of a JFrame. My question is, does the external JFrame or JScrollPane need to know that the Animator has objects that are listening for mouse events, or is it enough for the Animator itself to know?
Thanks in advance,
aron

Never mind, I figured it out. The answer was "yes indeedy, it is enough for just the Animator to know". I attached an anonymous mouselistener to the Frame object, and it registered nicely.
