Wow! Dave Hersey wrote a very detailed and comprehensive post that must have taken a long time. Sadly, I disagree with almost all of it.
NSMatrix is an "older" class that predates the "data source" design pattern that emerged (i think) in NeXTstep 3.0 in about 1994 as I recall. I think NSMatrix was in Nextstep 0.8 in 1988. I highly discourage sub-classing NSMatrix. To use NSMatrix... Before adding any rows or columns to your matrix, set it's cell class with setCellClass: or its prototype cell with setPrototype: but don't do both. Add rows with addRow and add columns with -addColumn until you have enough cells for all of your data. Then loop through the rows and columns calling cellAtRow:column: and configuring each cell based on your data. The better approach is to use NSCollectionView in Leopard. http://developer.apple.com/documentation/Cocoa/Reference/NSCollectionView_Class/Introduction/Introduction.html NSCollectionView is much more flexible and more supportive of MVC design using less overall code. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
