Hi there, I've been fiddling with NSAttributedString lately, and the way to display them through Core Text. In the docs, I've read that NSAttributedString and CFAttributedStringRef were supposed to be "toll free" bridged; I assumed that meant that one could be used in lieu of the other with (or maybe even without) a simple cast.
But I found this is not true. Specifically, I was getting strange errors like "CFSet[Stroke|Fill]ColorFromColor : invalid context 0x0" each time I printed my NSAttributedString by CTLineDraw(), although I had a perfectly valid context. The glyph were drawn, but always in black, while I was attempting to get another color via the NSForegroundColorAttributeName. At the end, I had to replace the pair (NSColor, NSForeground…) by a (CGColorRef, kCTForeground…), and now it works. Is that supposed to be a "normal" behavior, did I misunderstand the meaning of "toll free", or is it a bug? Thanks! Vincent PS : conversely, I found that NSFont * and CTFontRef are really equivalent._______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
