Spring Framework Paste Image from Clipboard on JFrame in Java

An example on pasting an image that is on system clipboard in Java on a JFrame. Here we've used a JLabel and set the image from the clipboard to it as icon.


Example




// Import for BorderLayout

import java.awt.*;



// Import for JFrame, JLabel

import javax.swing.*;



// Import for Clipboard, DataFlavor

import java.awt.datatransfer.*;



// Import for BufferedImage

import java.awt.image.*;



class PasteImage extends JFrame

{

JLabel l;

 public PasteImage()

 {



 // Set frame properties

 setTitle("Paste Image");

 setLayout(new BorderLayout());

 setDefaultCloseOperation(EXIT_ON_CLOSE);

 setVisible(true);



 // UnsupportedFlavorException, IOException can be raised.

 try

 {



 // Get image type data from the clipboard (Object type is returned) but type casted to BufferedImage

 l=new JLabel(new ImageIcon((BufferedImage)Toolkit.getDefaultToolkit().getSystemClipboard().getData(DataFlavor.imageFlavor)));



 }catch(Exception e){



  // If image is not found, try text!

  try

  {



  // Create a JLabel containing text that is in the clipboard

  l=new JLabel((String)Toolkit.getDefaultToolkit().getSystemClipboard().getData(DataFlavor.stringFlavor));



  }catch(Exception e1){

  // If nothing was there in the clipboard..

  l=new JLabel("Nothing is there in the clipboard!");



  }



 }



 // Add the JLabel to the frame

 add(l);

 

 // Pack it tightly!

 pack();



 // Center the JFrame

 setLocationRelativeTo(null);



 }



 public static void main(String args[])

 {



 new PasteImage();



 }



}

Explanation


Toolkit.getDefaultToolkit().getSystemClipboard(): Toolkit class has a public static method getDefaultToolkit() which returns an instance of the java.awt.Toolkit class which is useful for calling the normal public method getSystemClipboard(). This method returns the java.awt.datatransfer.Clipboard object which will further be used to get data from the system clipboard.

getData(DataFlavor.imageFlavor): Get the data in the clipboard that is in the form of an image.

Note: To make this program successful and see an image, before executing the program don't forget to copy any image to the clipboard.

Output
