Timing Framework를 사용하는 작은 클래스가 있습니다 (http://java.net/projects/timingframework/).Java Timing Framework의 PropertySetter가 내 속성과 함께 작동하지 않습니다.
class Kula extends JPanel {
private Animator an;
private int xp;
private int yp;
private Color kolor;
public Kula(int x, int y) {
this.xp = x;
this.yp = y;
this.kolor = Color.RED;
TimingTarget tt = PropertySetter.getTarget(this, "kolor", Color.RED, Color.BLUE);
an = new Animator.Builder().setDuration(2, TimeUnit.SECONDS).addTarget(tt).build();
}
public Color getKolor() {
return kolor;
}
public void setKolor(Color kolor) {
this.kolor = kolor;
repaint();
}
public Animator getAnimator() {
return this.an;
}
@Override
public void paintComponent(Graphics g) {
super.paintComponent(g);
g.setColor(kolor);
g.fillOval(xp, yp, 20, 20);
}
}
당신이 특정 색상 및 위치 (XP 및 YP)와 타원을 그립니다 볼 수 있듯이 : 여기에 코드입니다. Animator도 있습니다. 생성자에서 Animator를 만들지 만 선형 Interpolator (기본값)를 사용하여 kolor 변수를 변경하기 전에 TimingTarget을 만듭니다. 나는 getter와 setter를 가지고 있지만 내 애니메이션을 시작할 때 나는 예외 얻을 :
내가 선을 변경할 때, 흥미로운 무엇

TimingTarget TT = PropertySetter.getTarget (이, "칼라"를 , Color.RED, Color.BLUE);
에
TimingTarget TT = PropertySetter.getTarget (이 "배경"Color.RED, Color.BLUE);
모두 괜찮습니다. 내 패널의 배경이 올바르게 변경됩니다.
내 PropertySetter가 kolor 변수와 작동하지 않는 이유는 무엇입니까?
P. 폴란드어로 "Kula"는 구체를 의미하고 "kolor"는 색상을 의미합니다.
