JTextArea画Java？
这是代码。不知道为什么文本区域不显示背景图像
import java.awt.*;
import javax.swing.*;
public class UserInterface extends JFrame {
public static void main(String[] args){
System.out.print("Yes the application is working!");
drop();
}
public static void drop(){
javax.swing.JFrame frame = new javax.swing.JFrame( "FileDrop" );
//javax.swing.border.TitledBorder dragBorder = new javax.swing.border.TitledBorder( "Drop 'em" );
JTextArea text = new JTextArea(){
{setOpaque(false);}
public void paint (Graphics g)
{
ImageIcon ii=new ImageIcon("/Users/tushar_chutani/Downloads/Play1Disabled.png");
Image image= ii.getImage();
g.drawImage(image,0,0,null,this);
super.paintComponent(g);
}
};
frame.setBounds( 50, 50, 167, 167 );
frame.setDefaultCloseOperation( frame.EXIT_ON_CLOSE );
frame.setVisible(true);
}
}
这是整个代码。 如有任何帮助，我们将不胜

主要问题是您没有将文本区域添加到框架中。
其他问题是您应该从重写的paint()方法中调用paint()，而不是paintComponent()。
另外，您不应该在 Paint() 方法中读取图像。
The main problem is that you didn't add the text area to the frame.
Other problems are that you should be invoking paint(), not paintComponent() from the overriden paint() method.
Also, you should not read the image in the paint() method.
