I'm replying to myself in a 4 month old thread, so this might show
up correctly in your newsreader.
This is documenting a behavioral change between OS X 10.3.9 and
10.4. It is a (potentially serious) bug, and while I like it, it
might cause others trouble. So be careful before you upgrade.
When I type:
IDL> window
from an OS X X11 xterm the IDL plot window does not get the focus.
So far, this is nothing new to those of you using Terminal.app, and
is actually the behavior I requested long ago (and below in this
email).
But now the window *will not* accept focus, even if I mouse over,
click on it, whatever. A WIDGET window does get the focus and
behaves correctly.
The problem with this new behavior, is if I type:
IDL> window
IDL> zoom
I now cannot quit the zoom procedure (because it relies on window
events (right click) to quit). I have to CTRL+z and then 'kill' my
IDL session :(
So beware... any of you that use non-widget window interactive code
(CURSOR, ZOOM, etc.) on OS X, you probably don't want to upgrade to
10.4 right now.
Of course, there is the chance this is local to my machine. Can
anyone verify this? Is it some strange setting in my .xinit or
.Xdefault file?
If this exists on others, what is the procedure for alerting Apple /
RSI? I assume this is an Apple bug as I haven't done anything new
with IDL between yesterday and today, all I did was upgrade my OS.
-k.
