Java如何正确对齐JTextField内容？
为了证明JTextField内容的正确性，我们可以调用类的setHorizontalAlignment(JTextField.RIGHT)方法JTextField。
package org.nhooo.example.swing;
import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.SwingUtilities;
import javax.swing.WindowConstants;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.FlowLayout;
public class TextFieldRightJustify extends JFrame {
public TextFieldRightJustify() {
initComponents();
}
public static void main(String[] args) {
SwingUtilities.invokeLater(() -> new TextFieldRightJustify().setVisible(true));
}
private void initComponents() {
setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
setSize(200, 200);
Container container = getContentPane();
container.setLayout(new FlowLayout(FlowLayout.LEFT));
JTextField textField = new JTextField(15);
textField.setPreferredSize(new Dimension(100, 20));
//右对齐JTextField的内容
textField.setHorizontalAlignment(JTextField.RIGHT);
container.add(textField);
}
}
