我有JTextArea一个JDialog. JDialog使用一个GridLayout.
我想在每行上有 7 位数字JTextArea(每行将是 7 个int注册号)。出于用户体验的原因,我希望在JTextArea一行达到 7 个字符时添加新行或停止扩展。
不起作用的事情: - 在JTextArea构造函数中指定列数-matriculesText.setLineWrap(true);和matriculesText.setWrapStyleWord(true);
我担心uploadDialogManager.setHgap(20);可能会破坏密码。我想知道是否JDialog应该有一个固定的大小。
这就是我构建我的方式JDialog:
// initialization
Dialog uploadParent = null;
JDialog uploadDialog = new JDialog(uploadParent);
GridLayout uploadDialogManager = new GridLayout(UPLOAD_DIALOG_ROWS,
UPLOAD_DIALOG_COLUMNS);
// uploadDialog properties
uploadDialog.setSize(new Dimension(UPLOAD_DIALOG_WIDTH, UPLOAD_DIALOG_HEIGHT));
uploadDialog.setLayout(uploadDialogManager);
uploadDialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
//Set up the horizontal gap value
uploadDialogManager.setHgap(20);
//Set up the vertical gap value
uploadDialogManager.setVgap(20);
//Set up the layout of the buttons
//uploadDialogManager.layoutContainer();
// components initialization
JLabel exerciceLabel = new JLabel("exercice number : ");
JComboBox<Integer> exerciceNumbers = new JComboBox<Integer>
(EXERCICE_NUMBERS);
JLabel matriculeLabel = new JLabel("please enter your matricules, one per
line : ");
JTextArea matriculesText = new JTextArea(1, 1);
JButton confirm = new JButton("confirm");
JButton cancel = new JButton("cancel");
matriculesText.setLineWrap(true);
matriculesText.setWrapStyleWord(true);
