我的java接口有問題，我想顯示一個菜單欄和工具欄以及一些標籤和文本框，但是每次使用gridbaglayout時都沒有顯示我的標籤作爲我的文本字段，它只顯示我的菜單欄和工具欄可以幫助我與這一個，我搜索先生（谷歌）關於這個問題，但無法找到一個體面的解決方案與我的問題，我只是新手在Java和我希望Java可以作爲我的編程語言在我的下一個項目中使用。工具欄和菜單欄的網格包佈局
這裏是我的代碼：
package Forms;

//frame.setResizable(false);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(300, 300);

public static JPanel dataPanel()

return panelData;
}
public void MyToolBar()

frame.setJMenuBar(menuBar);
//Menus
menuFile = new JMenu("File");
menuBar.add(menuFile);

menuFile.add(itemSave);
menuFile.addSeparator();
iconMenu = new ImageIcon(getClass().getResource("icons/print.png"));
itemPrint = new JMenuItem("Print", iconMenu);
menuFile.add(itemPrint);
menuFile.addSeparator();

subFont1 = new JRadioButtonMenuItem("10 Pixel");
menuSetting.add(subFont1);
group.add(subFont1);

menuSetting.add(subFont2);
group.add(subFont2);

group.add(subFont3);
subFont4 = new JRadioButtonMenuItem("16 Pixel");
menuSetting.add(subFont4);
group.add(subFont4);

menuSetting.add(subFont5);
group.add(subFont5);
menuSetting.addSeparator();
checkPrefer = new JCheckBoxMenuItem("Preference");
menuSetting.add(checkPrefer);
group.add(checkPrefer);
iconMenu = new ImageIcon(getClass().getResource("icons/close.png"));

iconMenu = new ImageIcon(getClass().getResource("icons/view.png"));
itemView = new JMenuItem("View Users", iconMenu);
menuOption.add(itemView);

menuOption.add(itemReports);
}
}
通過我只用一個標籤的方式和文本字段僅用於測試目的。
*「我的Java界面有問題」，*換檔鍵似乎也有問題。如果沒有，請在每個句子的開始處使用它，如「I」和課程名稱等。這樣可以使文本更易於閱讀。你不會想讓它變得更難以幫助我們，對吧？ –
對不起，對於語法我總是忘記大寫每個第一個字母。 – Zyrax
您可以使用'UIManager'中的圖標使您的示例自成一體，如[此處]（http://stackoverflow.com/a/7935040/230513）所示。 – trashgod
