Java Swing容器不會出現

我正在通過Java設計一款遊戲，將Swing作爲我的GUI。 NetBeans是我的編輯器，我試圖使用它們的編輯器模式，但是無論何時運行代碼，都不會顯示任何內容。我試着把它建成一個罐子，但是當我運行這個罐子時，沒有任何東西出現。Java Swing容器不會出現

這裏是我的代碼：再次

package kraz; 
public class KrazGUI extends javax.swing.JFrame { 
    public KrazGUI() { 
     initComponents(); 
     setVisible(true);

請學習如何使用代碼構建gui，並且不要使用任何工具來構建Java中的gui，否則，您將難以維護或修改代碼。 – 2012-07-17 17:35:05

當我運行JDK1.6下此代碼時，窗口顯示就好了。雖然，我不得不註釋掉下面一行是JDK1.7 API

setType(java.awt.Window.Type.POPUP);

我想這行是問題。你使它成爲一個彈出式窗口。我會建議嘗試Type.NORMAL。

小側面說明：您應調整的主要方法觸發對EDT的UI代碼：

public static void main(String args[]) { 
    EventQueue.invokeLater(new Runnable() { 
     @Override 
     public void run() { 
     new KrazGUI(); 
     } 
    }); 
    }

謝謝，這完美解決了這個問題！ – RipIt 2012-07-17 17:46:06

我能夠在Eclipse中執行程序，絕對沒有probs。 和我的Java版本是版本「1.7.0_03」 enter image description here

但仍然遵循以下這兩點有一個更好的方法。

1.從main方法中取出組件的聲明，並將它們放在Class作用域的類的開頭。

2.放置setVisible(true)主

在主使用這...

SwingUtilities.invokeLater(new Runnable() { 
    @Override 
    public void run() { 
     Test8 t = new Test8(); 
     t.setVisible(true); 
    } 
});

我剛剛粘貼你的代碼Eclipse和它似乎是工作（Java 7中）：
