Is it bad practice (Apple Interface Guidelines) to have a sheet window within a sheet window?
Does the framework allow you to do that? I did a quick search and there doesn’t seem to be anything about it, other than this one thread < http://www.cocoabuilder.com/archive/cocoa/13226-sheets-within-sheets.html > The following quote is something that stuck out as good advice…
Yes, it does allow you and I haven’t got any weird results but it felt kind of wrong. I’ll look at an alternative approach
You can use a page panel in the sheet… Might be okay?
Yes!
If you must display another modal dialog, make it a modal dialog. I’ve seen a few apps that do display nested sheets, but Apple advise against this. I also seem to recall that I personally have had technical issues when using nested sheets also.
Not that I think it’s a good idea, but there are a few places in the system that use sheets inside sheets. For example, the printing dialogs.
Ha ha ha! You’re quite correct, Apple don’t even obey their own design guidelines! The save as PDF dialog is a nested sheet.
