Trying to return focus to a window

Trying to return focus to a window

[Richard Riley]

I have tried two ways to have the focus return to the source
buffer/window when "execute buffer" is done using python integration
as outlined here :

http://www.emacswiki.org/emacs/PythonMode#toc10

The two ways I have tried (both using defadvice) are:

,----
| ;; (defadvice py-execute-buffer (around stay-current-buffer activate)
| ;;   "This advice make cursor stay current position after execute `py-execute-buffer'."
| ;;   (save-excursion
| ;;     ad-do-it)
| ;;   (message "py-execute-function done"))
| 
| (defadvice py-execute-buffer (around stay-current-buffer activate)
|   "This advice make cursor stay current position after execute `py-execute-buffer'."
|   (let ((remember-point (point))
|         (remember-window (selected-window)))
|     ad-do-it
|     (message "focus stuff done")
|     (select-window remember-window)
|     (goto-char remember-point)))
`----

But in both cases the cursor stays in the iPython window (same
frame). Can someone suggest how best to get the cursor back into the
python buffer when I execute py-execute-buffer? is there something
fundamentally wrong with the approach I have taken above or a naive code
error?

thanks,

r.

You could try save-selected-window instead of save-excursion.

Hi, Kevin.

Now i'm debugging it.
I have use save-selected-window defadvice.

Advice is not problem (although use save-selected-window is simple, but
effect same as second advice).

But problem is not at advice, is some code make focus on iPython buffer
after `py-execute-buffer'.
