Well, it is sometimes useful to be able to get the bounding rect that a string will have after it is laid out and wrapped to a specified constraint size, such as a fixed width but an open-ended height. For example, when I create a printing view I specify NSZeroRect for the initial frame, then in the printing view itself I reset the frame to the bounding rect every time the user changes print panel settings that affect the size. As Matt points out, I can do all that with text layout, but I'm looking for shortcuts. I would like a method that truncated the string to the rect returned by this method when both width and height are constrained. But what I would like even more than that is to get the character index at which it was cut off based on the constraints. Then I could truncate the string myself, or do other things with the index. I would also like to be able to calculate the laid-out rect of successive page rects within the overall string, although this would have to be done in a way that didn't re-calculate the rect of all the preceding page rects. -- Bill Cheeseman b...@cheeseman.name _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
