在运行时Java添加和移动组件

时间：2012-10-01 14:00:43

标签： java swing button label

我想在运行时添加，移动和设置组件的属性（字体和旋转）。

换句话说，我需要添加一个按钮，一个标签，使用鼠标拖动它们并在运行时设置组件的属性。是否有任何Java摇摆或类似的示例？

这是我的代码 ： 

import java.awt.*;
import java.awt.event.*;
import java.awt.geom.AffineTransform;
import java.awt.image.AffineTransformOp;
import java.awt.image.BufferedImage;
import java.awt.image.BufferedImageOp;
import java.io.File;
import java.sql.SQLException;
import javax.imageio.ImageIO;
import javax.swing.*;
import javax.swing.border.Border;
import javax.swing.border.LineBorder;
