Create a bitmap context and call -drawRect: recursively on your view hierarchy, setting up the graphics state and CTM appropriately as you go. You may want to factor out your drawing code from -drawRect: so that you can call it separately. That would be handy if you need to draw subtle differences between the in-view representation and the drag image. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
