When creating a new TextArea with scala.swing, there is no right-click contextmenu nor an undo functionality with Ctrl + z. Ctrl + [acv] btw works well.
How can I add these essential text-editing features?
I’m on Scala 2.9.
Thanks in advance.
It seems that there is no support for undo on the Scala level and as such you’ll have to do it using Swing and calling the Java API. For a tutorial on how to use UndoManager, see this link.
For the popup menu, see this question on SO.
