Java對話框圖標

Question

你需要添加什麼來選擇對話框的各種圖標？另外你如何使用自定義圖標？

謝謝！

Answer 1

你的意思是JDialog s？如果是這樣，你正在從Java教程尋找this page。下面複製的是來自該頁面的樣本，沒有截圖;看到如何使用自定義圖標的最後一個：

//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); 

在這最後一個例子，icon是Icon類型的對象。這個版本的showMessageDialog()的the Javadoc。
