Hi,

I just checked the behaviour on Mac OS X, here's a backtrace:

#0  -[SharedBookmarkController outlineViewColumnDidResize:] (self=0x143ff00, _cmd=0x906c5968, aNotification=0x1447370) at SharedBookmarkController.m:355/private/automount/Network/Users/znek/Projects/mulle-private-cvs/znek/Bookmarker/
#1  0x907eaf7c in _nsNotificationCenterCallBack ()
#2  0x90168580 in CFStorageDeleteValues ()
#3  0x90165ca0 in _CFNotificationCenterPostLocalNotification ()
#4  0x9313e054 in -[NSTableColumn _postColumnDidResizeNotificationWithOldWidth:] ()
#5  0x931672bc in -[NSTableColumn setWidth:] ()
#6  0x932093dc in -[NSOutlineView _resizeOutlineColumn] ()
#7  0x93208af4 in -[NSOutlineView expandItem:expandChildren:] ()
[...]

This is what my delegate receives in its - (void)outlineViewColumnDidResize:(NSNotification *)aNotification
 delegate method:

2003-03-13 16:47:09.271 Bookmarker[662] -[SharedBookmarkController outlineViewColumnDidResize:] NSOutlineViewColumnDidResizeNotification:NSConcreteNotification 1447370 {name = NSOutlineViewColumnDidResizeNotification; object = <BMOutlineView: 0x1444da0>; userInfo = <CFDictionary 0x2674f0 [0xa01303fc]>{type = immutable, count = 2, capacity = 2, pairs = (
0 : <CFString 0xa3083fb8 [0xa01303fc]>{contents = "NSTableColumn"} = <NSTableColumn: 0x14477f0>
2 : <CFString 0xa3083fc8 [0xa01303fc]>{contents = "NSOldWidth"} = <CFNumber 0x1709cd0 [0xa01303fc]>{value = +197, type = kCFNumberSInt32Type}
)}}


It appears that on Mac OS X NSTableColumn posts both notifications, so it would be best to do this on GNUstep as well.

Cheers,

Marcus
