public class CopyPasteTextBox
extends com.google.gwt.user.client.ui.TextArea
implements com.google.gwt.user.client.Event.NativePreviewHandler

TextArea that handles cut, copy and paste events inside the spreadsheet.

It works by intercepting the keyboard shortcuts for cut, copy and paste and moving focus to a hidden textfield. In the textfield we can listen to oncopy and oncut events, and put our string into the HTML clipboard instead of the normal one.
