Fiji grabs focus during long scripts

When I am running a script that takes some time, I do other things like
deal with email, use a text editor or LaTeX, etc. the problem is that
during the script, Fiji often grabs focus ( presumably when it displays
an image window, or maybe also when it displays any window). When this
happens, whatever I have been typing is picked up by Fiji as shortcut
keys, and it usually messes up whatever is running.

Can this behavior be prevented? Is there a way to prevent ImageJ form
grabbing focus during execution of a script?

Tnx in advance

Hi Aryeh,

I'd recommend using 'setBatchMode(true)' in macros whenever possible to
prevent new windows from being opened.

Other than that, you can use any other supported scripting language
(e.g. Groovy or Jython) to interact directly with the Java API of
plugins, and work with objects headlessly instead of having to rely on
the active image window.

Cheers
Jan

I usually program in Jython. However, this problem occurs there also, I
assume that the trouble there occurs when I am using the IJ.run method,
since that opens image windows. I try to use the API calls, but
sometimes I use a plugin that is much easier to run using IJ.run.

I found that when using the IJ.run method, is is often necessary to
first display an image (ie, to use the imp.show() method) before running
the command in IJ.run. I assume this happens for methods where the
ImagePlus is not passed as an argument, and they ge the image from teh
open and active ImageWindow.

Best regards

Re: Fiji grabs focus during long scripts

Dear Aryeh,
I'm under Windows (= 7) OS and when I have similar issues to what you described, I just use the "Windows + m" keys combinaison in order to minimize all windows.
Following, I click then on the task bar the software(s) I want to use (you name them) which I need thus to be again maximized.
By doing so the ImageJ windows aren't anymore coming to the front.
My best regards,
Philippe

Dear Philippe,

Thanks for your reply. I am not sure I can do the same on my Linux
machine, but I may be able to do it with workspaces.

Best regards
