Hi All,
I've got an app that I'm creating NSTableColumn's on the fly and binding
them to an array controller. It all works fine but tonight I needed to
change one of the columns to have a NSButtonCell.
NSButtonCell *cell=[[[NSButtonCell alloc]init]autorelease];
[tc setDataCell:cell];
(tc is the table column) -- The problem is I lose the 'value' binding (I
want to bind the button cell title to the array controller). Previously I
was able to bind the table column to the controller thusly:
[tc bind:@"value"
toObject:siteLayoutController
withKeyPath:[NSString stringWithFormat:@"arrangedObjects.%@",item]
options:nil];
But after I set the data cell to a NSButtonCell it loses the 'value' binding
-- The bindings left are not terribly interesting:
*po [tc exposedBindings]*
Previous frame inner to this frame (gdb could not unwind past this frame)
<NSCFArray 0x1eab6fe0>(
target,
argument,
width,
font,
fontSize,
fontFamilyName,
enabled,
editable,
minWidth,
fontBold,
headerTitle,
fontName,
maxWidth,
fontItalic
)
I'm just about going crazy here -- is it possible to bind a NSButtonCell
title?
-John
