כמובן חוץ מלזהות שכפתור נלחץ יש עוד אפשרויות?

אני רוצה לזהות גם רק כשהעכבר עובר עליו, זה אפשרי?

יש לך את המחלקה MouseListener שהיא יותר משוכללת מ Action Listener

public class Mouse implements MouseListener
{
	public void mousePressed(MouseEvent e)
	{

			}
	public void mouseReleased(MouseEvent e)
	{

	}
	public void mouseClicked(MouseEvent e)
	{

	}
	public void mouseEntered (MouseEvent e)
	{

	}
	public void mouseExited (MouseEvent e)
	{

	}

לצערי זה לא עובד לי.

תראה את הTREAD הקודם שלי כדי להבין תמצב(עדין בעמוד הראשון)

הכנסת את הקוד ב- MouseEntered()?

תראה את כל הקוד הרלוונטי.
