Thanks for the reply, I'm a newbie and I'm still trying to figure out how are things done in Cocoa.
I have another related question I'd like to ask you guys, cause I've searched through documentation and tutorials but I cannot find the exact answer. I'm trying to implement Model-Controller-View in my code. So, so far I created a class called FilterBank with all the data to be plotted plus a method to init from a file. Then I included one instance of the class FilterBank in the myDocument class. When I open a file, myDocument will read and load all the data to the class calling the initFromFile: method of FilterBank, that works ok. Then I can subclass NSView to hold and plot the image using NSImageRep, etc. My problem is with the controller. I subclassed NSViewController (FilterBankViewController) and tried to bind the class with the owner of the file. But I noticed that in IB I cannot do that, actually the bind tab says it's "Not Applicable". I don't understand why though, b/c I learned in a tutorial that loads data from a file and puts that into a table, that you need an NSArrayController to mediate between the table and the file owner. What kind of controller should I use here? Thanks.

Thanks for the info, this is so very interesting for me, but as you said I'm still trying to accomplish much more basic stuff here. > > I don't use NSImage; my custom image views do some drawing at lower levels; > so I don't know for sure what all formats are supported.
