SWT: How to recreate a default context menu for text fields

Question

I need to add some items to the default context menu of a text control in SWT, but already found out I cannot modify this menu and have to create a new one from scratch.

But how do I emulate the default functions Undo, Cut, Copy, Paste, Delete? Do I really have to re-implement all this Clipboard stuff for myself? And I don't even know how to access the Undo history of the control. Is there some maybe dirty hack to emulate the key codes that achieve the functionality?

Answer 1

The StyledText has built-in support for Cut, Copy & Paste:

StyledText editor = new StyledText(...);
editor.invokeAction(ST.CUT);
editor.invokeAction(ST.COPY);
editor.invokeAction(ST.PASTE);

As for the Undo operation, I'm afraid you'll have to implement it yourself. SWT doesn't have anything useful here, AFAIK. Here's a good start if you want to do it yourself: SWT Undo Redo.
