Hello all and merry christmas, I have a text editor program that I wrote and on the whole it works very well, but I've struggled on and off with a recurring annoying issues. Lines are drawn across the NSTextView below where I am writing. Sometimes the text also appears "doubled"; it looks darker and slightly larger.
http://www.cantgetnosleep.com/glitch_lines.png This problem only seems to happen when I am in the paginated view, so it's likely some issue in my pagination algorithm. I'm guessing it's a matter of either calling or not calling one of the various display-refresh-related methods but I'm not sure. Some more background: the text system allows the user to view multiple NSTextStorage-NSTextContainer-NSTextView systems in a single master view by laying them out on the screen in pages. So that on a single screen you will have a heirarchy like: NSTextView > NSTextContainer NSTextView > NSTextContainer > NSTextStorage NSTextView > NSTextContainer NSView -> NSTextView > NSTextContainer NSTextView > NSTextContainer > NSTextStorage NSTextView > NSTextContainer NSTextView > NSTextContainer > NSTextStorage NSTextView > NSTextContainer NSTextView > NSTextContainer NSTextView > NSTextContainer The list of visible NSTextViews needed can get quite large, so as an optimization the pagination algorithm starts at the currently being edited NSTextStorage-Container-View and does that in the foreground before laying out the rest of the system on a separate thread in the background (they are hidden while being pushed to a separate thread). The bug/issue typically occurs when I start hitting "return", which causes the pagination algorithm and layout system to kick in, leaving behind the lines and bold-looking text. It always clears if I scroll or click the mouse over it or highlight that area. Many thanks! Hopefully somebody can help me figure this out.
