Hi all,
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.
2) Using the mouse tracking approach that I copied from:
http://code.google.com/p/fskit/source/browse/trunk/FSKit/Sample Apps/FSSearchDemo/SFHFRatingCell.m?r=37
This didn't work either (it also sets the objectValue of the cell)...
I guess I am missing something fairly obvious, but I've been searching
through the docs for it, and I can't find it. Any help would be
greatly appreciated...
In IB I bound the table column to the arrangedObjects.priority of the
array controller of the table. I have a coordinating controller that
initializes and sets the custom cell on the column in it's awakeFromNib.
Reading the binding reference for NSTableColumn seems to indicate to
me that the cell's objectValue is what gets bound to the managed
object's property, so it seems what I am doing should just work, and
it just does not.
TIA,
F
