Question

java的JTextArea里怎么能把文字方向改变

Answer 1

如果输出多行，建议不要用JTextArea和JTextArea，你可以用JTable试试，我做的个图书管理就用的这个来显示查询出来的书籍，感觉比较好排，而且还可以接收鼠标消息，如响应右键等。 import java.awt.BorderLayout; import javax.swing.JFrame; import javax.swing.JTable; class Test extends JFrame{ public static String[][] bookTableData = new String[3][6]; { for (int i = 0; i < bookTableData.length; i++) { bookTableData[i] = new String[]{"1","JAVA","雷名","25.6","张三","2008/12/11"}; } } private static String[] bookTableName = new String[] { "图书编号", "图书名", "图书作者", "图书价格", "借书人", "借出日期" }; private static JTable bookTable = new JTable(bookTableData, bookTableName); Test(){ this.setLayout(new BorderLayout()); this.add(bookTable,BorderLayout.NORTH); this.setBounds(0,0,500,300); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setVisible(true); } public static void main(String[] args) { new Test(); } }
