Hi list ?
Is there a way to know what part of an attributed string fit in a
rectangle, taking the line breaking mode into account ?
For example, let's say I have an attributed string whose string is
"Hello COCOA-DEV List !" and whose line breaking mode is
NSLineBreakByWordWrapping. And let's say that I have a rectangle that
is too narrow to fit the entire string and that will only be able to
contain "Hello COCOA-DEV" when the attributed string is drawn inside.
How can I know programatically that the word "List" has been truncated ?
Just in case, I need this because I'd like to create a control that
can wrap a long string into multiple lines and then truncate the tail
of the string with an ellipsis when the number of lines is equal to a
limit I'll fix.
For example, I want a control that would present the string "Can
someone help me on this ? I can't figure how to achieve this !" like
this, if I set the max number of lines to 2 :
Can someone help me
on this ? I can't figure...
To summarize : I wan't to be able to draw text just like the RSS
articles are presented in Safari !
Thanks by advance,
Eric.
