Java - How to hook into the Copy and Paste menu on the Mac OS

Question

I understand that you can:

// Where CustomMacOSXController implements implements MRJAboutHandler, ...
CustomMacOSXController macOSXController = new CustomMac         


        

Answer 1

Unlike the Mac OS X System and Application menu, the Edit menu is entirely under the purview of your program. You have to create and populate it with the approariate Action. The pre-defined subclasses defined in javax.swing.text.TextAction are handy, as they are aware of the focused component. See also this related Q&A and example. For example,

Action pasteAction = new DefaultEditorKit.PasteAction();
JMenuItem pasteItem = new JMenuItem(pasteAction);
JButton pasteButton = new JButton(pasteAction);

Addendum: To fully integrate your Edit menu into Mac OS X, you must tell the operating system to use your menu, using one of the approaches shown here. To obtain the platform-dependent modifier key, use getMenuShortcutKeyMask(), as shown here. Finally, Charles Bell's HTMLDocumentEditor is an example that uses the text actions.
