Hello,
I'm using an NSOutlineView
some of the rows in the list are showed empty also if they contain
some text data.
The problem seem to be that rows containing short text are correctly
visualized, while the ones containing very large text that exceeds the
NSOutlineView width
are showed as empty.
I don't know if it exists some flag that forces NSOutlineView to
visualize the content
(also truncated should be ok for me) for "large" content rows
in - (id)outlineView:(NSOutlineView *)olv
objectValueForTableColumn:(NSTableColumn *)tableColumn byItem:(id)item
[...]
if([[tableColumn identifier] isEqualToString:
@"YourColumnIdentifier"])
{
static NSDictionary * sTruncatedAttributes=nil;
if (sTruncatedAttributes==nil)
{
NSMutableParagraphStyle * sTruncatableStyle;
sTruncatableStyle=[[NSParagraphStyle defaultParagraphStyle]
mutableCopy];
if (sTruncatableStyle!=nil)

setLineBreakMode:NSLineBreakByTruncatingTail];
sTruncatedAttributes=[[NSDictionary alloc]
initWithObjectsAndKeys:sTruncatableStyle,NSParagraphStyleAttributeName,
nil];
[sTruncatableStyle release];

return [[[NSAttributedString alloc]
