java Swing自定义按钮，最大化到最小化，回来图标就不见了？
程序运行，单独点击最大化，最小化没有任何问题，但是如果先点了最大化，再点最小化
再从任务栏点回来，图标就不见了。
//最小化功能
public void minFunction(JLabel min){
min.addMouseListener(new MouseAdapter() {
@Override
public void mouseEntered(MouseEvent e) {
// TODO Auto-generated method stub
min.setIcon(new ImageIcon(hover_min));
}
@Override
public void mouseExited(MouseEvent e) {
// TODO Auto-generated method stub
min.setIcon(new ImageIcon(default_min));
}
@Override
public void mouseClicked(MouseEvent e) {
realizeMin();
}
});
}
//最大化功能
public void maxFunction(JLabel max){
max.addMouseListener(new MouseAdapter() {
@Override
public void mouseEntered(MouseEvent e) {
// TODO Auto-generated method stub
max.setIcon(new ImageIcon(hover_max));
}
@Override
public void mouseExited(MouseEvent e) {
// TODO Auto-generated method stub
max.setIcon(new ImageIcon(default_max));
}
@Override
public void mouseClicked(MouseEvent e) {
realizeMax();
maxFace();
if(getjFrameState() == 1){
realizeMax();
maxFace();
}else if(getjFrameState() == 2){
realizeNormal();//点击按钮实现最大化
normalFace();
}
}
});
}
//获取窗口状态
int jFrameState;
public int getjFrameState(){
jFrame.addWindowStateListener(new WindowStateListener() {
@Override
public void windowStateChanged(WindowEvent state) {
// TODO Auto-generated method stub
if(state.getNewState() == JFrame.NORMAL) {
jFrameState = 1;//新窗口正常化
}else if(state.getNewState() == JFrame.MAXIMIZED_BOTH) {
jFrameState = 2;//新窗口最大化
}else if(state.getNewState() == JFrame.ICONIFIED) {
jFrameState = 3;//新窗口最小化
}else if(state.getOldState() == JFrame.MAXIMIZED_BOTH) {
jFrameState = 4;//旧窗口最大化
}else if(state.getOldState() == JFrame.ICONIFIED) {
jFrameState = 5;//旧窗口最小化
}else if(state.getOldState() == JFrame.NORMAL){
jFrameState = 6;//旧窗口正常化
}
}
});
return jFrameState;
}
