Using NSTextView¹s native ability to embed image attachments, we have successfully implemented resizing of the image by using a resizable frame with a drag handle, and using setSize on the NSImage. Works great. Only one problem, re-archiving the NSAttributableString loses the image size change. Any way to fix this? Internally, in a CoreData auxiliary file folder, we archive NSAttributableString. Would we be better off storing it as RTFD?
I also see allusions to subclasses of NSTextAttachment, but I see no way to tell NSTextView, or its associates, to use such a subclass. NSTextAttachmentCell is a protocol. But who adopts this protocol? For an image, is this really a NSImageCell adopting this protocol? Or is it the NSTextAttachment? Confusion here. Documentation on attachments is sparse. We would also like to have the ability to set the baseline when an image is inserted, and change it when the image is resized. Certain NSPDFImageReps contain baseline info in private dictionaries, which we would like to use, when available. In view of the above, should we abandon NSTextView¹s paste/drag-in capabilities for images and override all the relevant methods to do our own attachment inserts using a custom NSAttachment class? Related question about NSImage. I¹ve never understood setSize in NSImage. Does this just affect the cached image, or does it have any impact on the underlying imageRep, such as resizing and remapping a bitmap? One more: I¹ve never found a straightforward way to make a textView re-layout all or a portion of the text. The best way I¹ve found is to call textContainerChangedGeometry. Works, but seems rather obtuse. Inquiring minds need to know. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
