- I'm trying to make a subclass of TextField object that cannot be copied
- with the cut/copy keys or cut/copy menu entries. I made a subclass called
- XTextField and set it up with a "empty" copy method (ie a copy method that
- does nothing but printf("copy method invoked").
- However, I can still copy the text and my custom copy method does not
- ever appear to get invoked during the COPY operation.
-
- I've read that all TextField objects share the same Text object for
- rendering text. Can I override the COPY method in this Text object somehow?
- Is this why my subclass of TextField with a custom COPY method will not
- work?
-
- Does anyone have/know of any examples of a TextField (or Text) subclass
- that cannot be copied?
-
- Thanks,
-
