I'm using code from the TextLinks sample (http://
developer.apple.com/samplecode/TextLinks/TextLinks.html) to get a
pointing hand cursor over links in my NSTextView subclass. But
this has broken the resize cursors that appear over the edges of
tables. I've tried calling [super resetCursorRects] at the
beginning and at the end of my subclass' -resetCursorRects method
and either will restore the table cursor behavior, but breaks the
link cursors. Any ideas? Do I now have to write code to handle
cursors for tables myself?
None of this should be necessary--links get the pointing hand
cursor by default, based on the text view's linkTextAttributes. If
you need custom cursors, you can use NSCursorAttributeName. If you
really need to override the default cursor handling in some way
that this doesn't support, don't use cursor rects; instead,
override mouseMoved:, call the super method, and then afterward set
the cursor if the mouse is over some region you are particularly
interested in, otherwise leave it alone.
Maybe it shouldn't be necessary, but I don't get a pointing hand
cursor by default. Maybe I'm doing something wrong. I just tried
making a new Cocoa Doc based project and added an NSTextView to the
doc nib window. Built and ran, then typed "http://www.apple.com"; in
the text view, right-clicked on it and chose "Make Link" - no
pointing hand. I assume that this should work based on your
statement. Is there something else I need to do?
I then subclassed NSTextView and overrode linkTextAttributes to
return the dictionary from super, with the addition of the pointing
hand cursor set as the object for the key NSCursorAttributeName
(thanks for that tip) and now I get a pointing hand. Since this works
and doesn't impact table cursors, this is what I'm going with.
Thanks!
