NB: In the process of writing this plea for help I've come up with a
workaround. (Don't you love it when you solve your problem while
asking about it? :) I'm posting this rather elaborate problem
description anyway, because it might help others and because it is
after all still a workaround and I'm sure there's room for improvement
both in the code and my understanding of the very powerful python-
applescript bridge.
------------------------------------------
Hi,
I hope I'm in the correct place with this problem -- I've found this
list through a link from the python-appscript page. My problem
probably falls between python and AppleScript but I've not been able
to find any clues on the web or in this list's archives. Please let me
know if there's a better place for me to post this!
I'm trying to script a Cocoa app I wrote to establish user level
tests. To that end I'm trying to populate a table view (backed by Core
Data) with entries. Thanks to Prefab's UI Browser I've had little
trouble identifying and accessing the UI controls from py-appscript.
However, progress has ground to a halt when I tried to change a value
in a table view cell. The code is the following:
...
table = scroll_area.tables[1]
row = table.rows[index]
text_field = row.text_fields[1]
text_field.value.set(value)
assert text_field.value() == value
This fails with:
File "create_document.py", line 47, in edit_customer
assert text_field.value() == value
AssertionError
According to the AppleScript code UI Browser auto generates for text
field value changes I'm doing the right thing by setting the value
property:
set value of text field 1 of row 1 of table 1 of scroll area 3
of splitter group 1 of window "Untitled" to "<string>"
It's just not working from appscript. I'm at a loss as to how to
propagate the value change to the model. I've found that I can make
the table cell highlight and change the actual displayed value by
inserting the following before "value.set(...)":
text_field.focused.set(True)
However, this only changes the displayed value. The assert still
fails. Of course I've tried inserting
text_field.focused.set(False)
after the calls to 'commit' the change to the table view but this does
nothing at all! Not even reset focus. I've also tried focusing another
element to commit the change but no luck.
I was thinking to perhaps send a "Return" key stroke and I've found a
way to do that (I'm using 'key_code' instead of 'keystroke', because I
don't know what the return key constant should be in appscript):
app('System Events').key_code(36)
Doesn't make a difference though :(
On a hunch I then tried the sequence of sending a regular keystroke
plus return and lo and behold, the following works for some reason
(does it have to do with the cell editor perhaps?):
text_field.focused.set(True)
app('System Events').keystroke(value)
app('System Events').key_code(36)
assert text_field.value() == value
This is a bit kludgy but at least it works. If anyone has any tips on
how to improve this it would be very much appreciated!
Cheers,
Sven
