Hi Group,
I am wondering if anyone can help me switch window focus
programatically, without the keyboard/mouse.
I've always been a bit bothered that the WINDOW procedure takes the
focus away from my xterm/emacs window and leaves it on the new
window. Usually (Linux window managers) ALT+TAB (or ALT+SHFT+TAB)
fixed it, so it wasn't a big deal.
But now I use Aqua/OS X, and ALT+TAB or CMD+TAB cycles apps, not
windows. CMD+` cycles windows, but only forwards, and if I have n
X11 windows open (n = 10 to 50; 2 monitors, 8 virtual desktops) it
takes a while to get back to n-1. CMD+SHFT+` doesn't do anything
unfortunately, even though SHFT usually means "cycle backward". This
leaves only the mouse to get focus back to the xterm/emacs, and I
don't like using the mouse.
So, I would like to change window focus using the shell, not the
mouse or keyboard.
I am resigned that if I type the PLOT command (which opens a window)
my emacs/xterm will not have the focus. But I have rolled my own
winDOH procedure that runs each time I start IDL:
PRO WINDOH, Window_Index, _EXTRA=e
if ( n_elements( Window_Index ) eq 0 ) then Window_Index = 0
; fill entire 2nd monitor
window, Window_Index, xsize=1280, ysize=1002, xpos=1920, ypos=454, _EXTRA=e
; Add a line here to set focus back to *me*
end
I would like add a line at the end that returns focus to the calling
window.
I have thought of the following methods, but what initial testing I
did tells me it is not very easy (for me)
1) Shell escape sequences
Not sure what this even entails, but I have glorped that it could be
a solution. Any advice?
2) AppleScript
I can cycle Finder windows, but X11 doesn't have an applescript
dictionary, so I don't think this can work.
3) Apple Universal Access
This allows programatic control of keyboard + mouse. I could fire a
mouse click, but that would require me to leave the pointer over the
parent. Keyboard control might be able to count the number of X11
windows and CMD+` cycle through them, but I have actually found the
cycling to be buggy w/ 2 monitors and virtual desktops. Some X11
windows are skipped. so I don't think this can work.
4) unix shell scripting
xev, xwininfo, etc...
I read some man pages, but have not gotten farther than that yet.
Any advice/help will be greatly appreciated.
Thanks,
-k.
