Hi Jeff,

you mean, your plugin kets the keys as it should be, but it will ALSO be
handled by ImageJ?

I´m not sure, which happens first, just did a quick internet search, there
is a

KeyEvent.consume

methods, which marks an event as already fully handled, you might give it a
try!?

Mit freundlichen Grüßen / Best regards

Hello Imagers,

I wrote a plugin a long time ago (for browsing 4d datasets from disc)
that extends the ImageWindow class, and creates a KeyListener to act
on the up, down, left, and right arrow keys. This worked well before
the default behavior was to magnify or reduce the ImageWindow using
the right and left arrow keys, as in more recent versions of ImageJ.
Now the plugin reads the key stroke and acts on it, but the key stroke
is passed to ImageJ, which then magnifies or reduces the ImageWindow.
I guess I'm stupid, but I don't see how to prevent this.

Any ideas would be deeply appreciated!

Cheers,

Jeff
