[TriLUG] twm simple question, I hope?

[Mike Norwood]

Hello,

I am trying to do something as simply and as quickly as possible, and 
wondered if anyone might still be familiar with controlling the twm window 
manager.  I wanted to use the simplest window manager that I could find to 
do this one specific thing and this seems to be it.  I am opening one 
terminal screen on startup, just xterm, which displays a software screen, 
which allows for the scanning of a barcode.  When this barcode is scanned, 
it opens a new window using the display (Imagemagick) program that shows a 
picture of the item that is scanned.    This works, but the problem is 
that I then have to click into the picture window to focus on it, so I can 
hit escape to exit it.  I then have to click back into the application 
window for the next scan.  Ideally I would like the new window to become 
the focus when it opens, so that the person using it would just need to 
view the picture, then hit escape, which closes the window and focuses 
back on the previous window for the next scan.

I realize I have been a little long winded with this explanation, but if 
anyone understands what I am asking and knows how to configure twm to 
shift the focus of the windows back and forth without the mouse clicks, 
your help would really be appreciated.

Thanks,  Mike Norwood
