Hi List,
I have a document window that can show the same data in more than
one way, very much like Finder, one view mode is an outline, the other
is a collection. Both are bound to the same data, so they reflect
changes automatically.
I was wondering if there is some way to tell a controller class (like
NSArrayController) to temporarily disconnect the bound view from the
data (other than removing the binding itself). It seems that the views
are updating the data even if they are not visible, consuming memory
and processor time. Moreover, NSCollectionView does seem to have
problems when it's not visible and the data changes (I get debug log
entries about assertion failures in NSView lockFocus).
Thanks
Markus
