Hi Florijan,
I've made an NSActionCell subclass for indicating the priority of
an object, similar to the rating column in iTunes. The visual
aspects of it are working fine, as well as displaying the correct
priority for table rows that have a priority value set.
The problem is setting the new priority when the user clicks on the
column. I've tried two approaches:
1) Setting the target of the cell to self, and in the action
message set the objectValue of the cell to the desired priority
(which I have no problem determining from the location of the mouse
click). Somehow that does not affect the bound NSManagedObject at
all.
If I understand you correctly, you have bound your table column to
an array controller, and are trying to change the data by changing
the table column. As far as I understand bindings (which isn't
much), you aren't supposed to (because it won't work) change the
data by programmatically adjusting the view (ie the table column
cell).
This makes sense, though it is unfortunate. I was hoping to somehow be
able to do it this way so that virtually all of the logic would be
encapsulated in my cell class, without the need for it to know much
about objects outside of it.
I suppose the other example that I found of this type of a table
column cell was not used with bindings, and consequently this approach
worked...
You should instead direct any programmatic changes to the data
itself, through the controller in a key-value compliant way. Then
the view will automatically reflect those changes.
I hope this helps. If ou need more detail, I'll try to follow up.
I am able to do this. I am not sure it is flawless, but it works as
far as I have tested it. I am not too happy about it as it scatters
the logic a bit, but it works.
Thanks for your help,
F
