Yes and no. The value of -wraps is what counts, but I didn't do it. (That's why I made the demo project.) Out of the box, [[NSTextFieldCell alloc] init] has -wraps = YES. This works fine in Mac OS 10.5, but in Mac OS 10.6, it causes the expansion frame to not bound its text (which yesterday I called "clipped"). The NSTextFieldCell returned by -[NSTableColumn dataCell] has -wraps = NO. That's why it works. However, setting wraps:NO causes the ellipsis to not appear in the normal drawing, and/or causes the text to not scroll to the left when you bump into the right edge while editing. Now, let me summarize -- I have three requirements: 1. Properly-drawn expansion frame. 2. Ellipsis appears when text overflows during normal drawing. 3. When editing, text should scroll left when you bump into the right edge. I considered three attributes of NSCell: -wraps -scrollable -truncatesLastVisibleLine Setting these to all eight possibilities (some are not allowed, since setWraps: sometimes affects -scrollable and vice versa), I found that there is no combination which satisfies all three requirements. So then I tried overriding three methods: drawWithFrame:inView: drawWithExpansionFrame:inView: editWithFrame:inView:editor:delegate:event: so that I could change the values of the three attributes before. But I am still unable to find the magic formula. However, I know there is a magic formula somewhere, because when I use the default cell returned by -[NSTableColumn dataCell], all three requirements are satisfied. Statically, I see that it sets all three attributes to NO. But when I try this with a raw NSTextFieldCell, only requirement 1 is satisfied. Maybe there is another attribute involved -- NSCell has several dozen more. Anybody got a good guess? _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
