iTunes-like tail truncation for attributed strings
-
Folks;
I have a source list type view.
I am using a tableView not an outlineView because it works for this
data set.
I have an attributed string which has an image and a name.
This is the only column in this tableView.
This tableView is contained in a splitView which allows this 'nav' to
be re-sized....
A lot of words to describe something quite similar to iTunes.
As you reduce iTunes playlist column size toward its minimum, the
playlists do a 'tail truncation' on any long text.
How do I achieve that?
What I am seeing regardless of many different settings, is that the
text 'breaks' at the space between the image and wraps to a a second
line.
I have Truncate Tail set in the Text Field Cell for the table column.
Can you achieve this with effect with IB and an attributed string or
is some other code solution necessary?
Thanks for any help!

Maybe this will point you in the right direction

BK;
Thanks!! Bingo!
The key for me:
"...The behavior can be controlled with -truncatesLastVisibleLine for
text cells..." This is a checkbox in IB, at the text cell inside the
tableColumn.
This in conjunction with the LineBreaks: truncatesTail setting
I did NOT have to make any changes to the attributed string which
simply specifies an baseline offset and the image
(attrStringWithAttachement)
God Bless Cocoa!
