Hello all,
I am working on a word processing problem. I have a paginated view
that has multiple text containers and text views laid out to form pages.
I have an intermittent bug where one line of text from another text
view/text container gets overlaid onto a line from the "current" text
view/text container. I think this always happens with the first lines,
such that one line is drawn on the top of the other line. The "ghosted
line" is still visible in the second container, and both lines change
if I edit that line. I can click on the text view or scroll and the
"ghost" line of text will often disappear or flicker and reappear
(perhaps as the text view is displayed?).
I think I've narrowed the problem down to calling NSLayoutManager's
method "rectArrayForGlyphRange". Basically I think that if I call this
and ask for a glyph range that is longer than what is contained in the
current text container, this is somehow causing other text to bleed
over. The doc's state that these arrays are reused by the layout
manager.
Has anyone else run into this? Is this the expected behavior?
Thanks - Andrew Hughes
