I am developing a custom view, sort of a simple graphic editor, where the user can draw graphic boxes of different size. Each box should display its own attributed string bounded by its own size, and when the user double-clicks any box, he becomes able to edit the box's text in-place.
I have read the docs and have a general understanding of the text system components: NSTextStorage, NSLayoutManager, NSTextContainer and NSTextView. However I wonder if some instances of these can be shared across different graphic boxes for better efficiency? I could go the simple and dull way and create a separate instance of NSTextView for each box, but I am afraid this could be a waste of resources, because layout manager is costy. Also, most of time I only need to display text in boxes, not to edit it. I thought it could be smarter to create a single shared instance of NSTextView per custom view, and re-attach it to different boxes when the user double-clicks a box. The rest of time I'd use NSTextStorage and NSTextContainer to just draw the string. Is this a good idea? In this case, what object instances should each graphic box have of its own? My guess is that each graphic box should have its own instances of NSTextStorage and NSTextContainer, but I am not sure what about NSLayoutManager? Can it be shared too, or it's going to be inefficient? How do I reconnect the shared components from a box to another box? Thanks. _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
