Java对话框图标

Question

您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？如果是这样，您正在从Java教程中寻找this page。下面复制的是该页面的样本，没有截图;请参阅最后一个关于如何使用自定义图标的信息：

//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);

在最后一个示例中，icon是Icon类型的对象。这个showMessageDialog()版本的the Javadoc。
