我覆盖了JFrame中的setVisible()函数.它所做的只是不断增长框架或缩小框架,直到它达到我想要的尺寸.这使得一个简单的动画.我的问题是,它是不稳定的,不平滑的,如果移动框架不能很好地工作.有没有办法可以做到更干净,更流畅,更光滑？

@Override

public void setVisible(final boolean visible)

{

final int effectSpeed = 5;

if(effect == false)

{

super.setVisible(visible);

}

if(effect && visible)

{

//run the window opening effect

new Thread(new Runnable()
