Re: How do I find out the maximum extent that a morph can be set to, without this impacting the current extent of its owner morph?

The owner morph (a stickie note title bar) contains 3 submorphs:
1. a SimpleButtonMorph, to trigger collapse/expansion of the stickie  
note (collapsed = stickie note's editor submorph hidden)
2. a StringMorph: contains a summary -- a contracted copy -- of the  
stickie note's editor's contents. The length of that summary depends  
on the maximum amount of horizontal space available to the containing  
StringMorph.
3. a StringMorph: set to the last modification date of the stickie note.

Therein lies my problem: to determine the maximum space that #2 can  
occupy before provoking a resize of the stickie note, and given that  
stickie note widths are left to user discretion, i.e., vary.
