showing load progress for autosaved documents
i’m attempting to show load progress for complex documents. my document class defines readFromURL & this seems the natural place to do this; however, for autosaved documents the progress window does not show until the document window shows (in the same instant, after the load is complete). i expect this is something to do w/ readFromURL being sent from a background thread; but, there must certainly be some way to flush the progress window. all/any suggestions greatly appreciated. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

mouse tracking outside a window & dock tracking area
during mouse tracking it is often convenient to register movement outside view bounds. unfortunately, if the cursor is set to other than arrow, movement outside the bottom of a window may enter the dock’s tracking area causing the cursor to change to arrow for the duration of the loop. it is possible to inhibit the dock’s tracking area in the regular case w/ a setPresentationOptions bracket, e.g. NSApplication* a_= [NSApplication sharedApplication]; NSApplicationPresentationOptions pre_opt= [a_ presentationOptions]; [a_ setPresentationOptions:NSApplicationPresentationHideDock]; // ... tracking code [a_ setPresentationOptions:pre_opt]; however, this has no effect in full screen mode—the cursor is still set to arrow. does anyone (else) feel setPresentationOptions:NSApplicationPresentationHideDock should obtain equal result for both modes? in particular, why is this setting ignored in full screen? does anyone have a workaround? ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: unarchiving a font collection
hello to anyone that took notice of this issue & appology to fontDescriptorsInCollection: on further investigation i discovered, deficient descriptor-count return from fontDescriptorsInCollection may be remedied by recreating the problem collection(s) (in Font Book); it appears the problem lies elsewhere. thanks, edward m taffel On Jul 7, 2009, at 3:50 PM, edward m taffel wrote: hello list, as NSFontManager -fontDescriptorsInCollection is apparently unreliable, i would like to unarchive collections directly (it seems apple does not provide support for this): anyone had success with unarchiving a font collection? thanks to all in advance, edward m taffel ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
