Hi -
I'm fairly new to Cocoa and am trying to write a simple programmer's
text editor. My biggest challenge so far has been line numbering. I
have the algorithm for generating the line numbers, but my challenge
has been finding a way to display those line numbers and have them
scroll alongside the text in the NSTextView. I want to end up with a
nice clean look, similar to the one in SubEthaEdit.
I looked at the document nib file for SubEthaEdit and I can see that
they have a NSScrollView for the entire editing region. How does one
achieve the kind of line numbering effect that they have? Do I need to
create a custom view that has a NSTextField for the line numbers and
place that next to the NSTextView, then make that custom view the
document view of the NSScrollView? Or is there a better way to do
this? Can I create a nice clean separation like they have using only
the NSTextView? I've seen a few line numbering implementations that
draw the line numbers inside the NSTextView itself, but there was no
separation. The numbers appeared next to the text with a small gap,
but (IMHO) it looks a bit sloppy without a nice column to put the line
numbers in.
Any suggestions and/or code would be greatly appreciated. Thanks!
Josh
