Hello list, I have performed quick search through the list and couldn't find answer to my question.
I am trying to implement editable text view which changes text position (paragraphs positions, to be exact) according to the some text attributes. I know, that NSTextContainer is responsible for line rects calculation when text should be placed in known shape. Is it responsible for this when position depends on text attributes also? Reason I am asking is that in method lineFragmentRectForProposedRect:sweepDirection:movementDirection:remainingRect: I do not have any information about glyphs or characters range to be placed in proposed rect, only rect coordinates. Should I do this manually by accessing container -> text view -> text storage? Maybe NSLayoutManager or NSTypeSetter subclass would be better choice? Another thing I'd like to ask, is where should I adjust text view/text container size if this is necessary while typing? I have tried to do this after getting NSTextStorageDidProcessEditingNotification notification. But that raises an exception: >> Exception raised during posting of notification. Ignored. exception: '*** >> NSRunStorage, _NSBlockNumberForIndex(): index (0) beyond array bounds (0)' >> invoked observer method: '*** -[MyTestController >> _TextStorageContentChanged:]' observer: 0x14d60b10 notification name: >> 'NSTextStorageDidProcessEditingNotification' << Any help is very appreciate.
