Question

你需要添加什么来选择对话框的各种图标？另外你如何使用自定义图标？

谢谢！

Answer 1

你的意思是JDialog s？如果是这样，你正在从Java教程寻找this page。下面复制的是来自该页面的样本，没有截图;看到如何使用自定义图标的最后一个：

//default title and icon 
JOptionPane.showMessageDialog(frame, 
    "Eggs are not supposed to be green.", 
    "Message"); 

//custom title, warning icon 
JOptionPane.showMessageDialog(frame, 
    "Eggs are not supposed to be green.", 
    "Inane warning", 
    JOptionPane.WARNING_MESSAGE); 

//custom title, error icon 
JOptionPane.showMessageDialog(frame, 
    "Eggs are not supposed to be green.", 
    "Inane error", 
    JOptionPane.ERROR_MESSAGE); 

//custom title, no icon 
JOptionPane.showMessageDialog(frame, 
    "Eggs are not supposed to be green.", 
    "A plain message", 
    JOptionPane.PLAIN_MESSAGE); 

//custom title, custom icon 
JOptionPane.showMessageDialog(frame, 
    "Eggs are not supposed to be green.", 
    "Inane custom dialog", 
    JOptionPane.INFORMATION_MESSAGE, icon); 

在这最后一个例子，icon是Icon类型的对象。这个版本的showMessageDialog()的the Javadoc。
