#818 closed defect (fixed)

NSRunAlertPanel() hangs on Cocotron

Reported by: gb Owned by:

as of Cocotron 2845a0e2fa, doing:

(#_NSRunAlertPanel #@"title" #@"message" #@"Yes" #@"No" #@"Maybe")

from the main thread hangs, burning 100% CPU and (apparently) slowly leaking memory.

I haven't yet tried to create an ObjC example that demonstrates this, though it doesn't seem likely that it's CCL-specific.

  • Resolution set to fixed
  • Status changed from new to closed

r14659 tries to workaround this, assuming that my understanding of the problem is correct.

(In [14660]) When modifying a document's textstorage on Cocotron, explicitly call the document's #/updateChangeCount: method. (This ordinarily is the responsibility of the document's NSUndoManager, but Cocotron's NSUndoManager support is broken.) This gives visual indication of the document's modified state in the containing window's titlebar and modeline and notifies the document controller that it should prompt to save modified documents. Since NSRunAlertPanel() seems to now be usable on Cocotron (see ticket:818), this fixes ticket:813.
