Modifying the Macro Recorder

[JonKaplan]

Hello,
I am attempting to alter the Macro Recorder so that another plugin can be notified when the Recorder adds to its text.
I tried to copy the source code and add an underscore (as outlined at http://rsbweb.nih.gov/ij/docs/menus/plugins.html "Internal Plugins"). The new Recorder_ plugin runs fine and looks identical but does not do any recording. I believe this stems from not knowing what calls the Recorder methods.
If anyone knows how I could use a modified Recorder it would be much appreciated.

Thanks,
Jon

The problem is that your class will not be used, but the original one,
unless you put the .jar containing your class _in front of_ ij.jar in the
classpath.

But a much better way to do what you want to do is probably to register a
CommandListener:
http://rsb.info.nih.gov/ij/developer/api/ij/Executer.html#addCommandListener(ij.CommandListener)

This listener will be notified whenever an action occurred.

Hi,

please reply-to-all when responding to me. If you reply to me privately
(and I then reply to you privately by mistake, too), then basically I
spend my time exclusively for you. All the while others might have been
interested in the discussion and could have learnt from it.

This is a fragile setup, since the recorder can get closed and reopened
(in which case it is _another_ recorder).

A better way might be to go with ImageJA (included in Fiji), which has a
CommandListenerPlus, providing you with more detailed information.
