Copy to clipboard

While working on the Baking Blogger’s special characters panel, I needed a way to copy the selected character to the clipboard. I used the following technique:

import java.awt.Toolkit;

import java.awt.datatransfer.*;

TextTransfer clipBoard = new TextTransfer();

Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();

clipboard.setContents(stringSelection, this);

clipBoard.setClipboardContents(button4.getText());

class TextTransfer implements ClipboardOwner {

@Override

public void lostOwnership(Clipboard clipboard, Transferable contents) {

}

public void setClipboardContents(String aString) {

StringSelection stringSelection = new StringSelection(aString);

Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();

clipboard.setContents(stringSelection, this);

}

}

Start with writing a class that implements the ClipboardOwner interface. This enforces you to implement the method setClipaordContents(String string){}
