Animer un JLayeredPane et convertir la valeur de "pos" avec DecimalFormat
Bonjour,
Je souhaite convertir la valeur de "pos" de la méthode setComponentConstraints() avec la classe DecimalFormat, mais j'ai une erreur à la ligne 48 de Login.java, auriez vous une idée?

private final DecimalFormat df=new DecimalFormat("##0.###");
....
TimingTarget target = new TimingTargetAdapter(){
@Override
public void timingEvent(float fraction){
double fractionCover;
if(isLogin) fractionCover = 1f - fraction;
else fractionCover=fraction;
fractionCover=Double.parseDouble(df.format(fractionCover));//Ligne 48 Login.java erreur ici
mig.setComponentConstraints(container, "width "+coverSize+"%, pos "+fractionCover+"al 0 n 100%");
bg.revalidate();
}
@Override
public void end(){
isLogin=!isLogin;
}
}; |
