NSView/NSTableView question
Hello, In my project I have a table view on the main window which accepts drops and the dropped files will show up as a list. All works normally at this point. However as an afterthought I was thinking to put an NSView on top with a graphic stating Drop files here or something to that effect so when the table view is empty the user doesn't have to stare at an empty table view. However I have run into a few issues and I was hoping someone could point me in the right direction or maybe let me know if I'm going about this wrong. Here are the issues I'm having: 1. Once a file is dropped onto my main window I'm trying to hide the NSView so the NSTableView will show through. It works but I'm having a difficult time to unhide the NSView when the table view goes back to empty 2. My table view is the data source since this part was already done. The table view is also the one receiving drops even when my custom view is visible. Is this wrong and do I have to make my custom view a data source too? 3. Since I have custom colors in my table view and now I'm setting the color in my custom view it creates some artifacts when dragging a file on my main window. I'm guessing there must be a conflict somewhere... Well again any pointers would be great. Much appreciated! rc___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: NSView/NSTableView question
Another approach that might be simpler: Set up a tabbed view with 2 views - one to receive drops with all your instructions, and the other to display the table. Switch to the drop view when the table row count is 0, and switch back to the table tab when valid drops are registered.

NSFetchedResultsController: different sort descriptors for different sections
I have a situation where there are two sections in a table view. The first section should have its rows sorted according to a certain index stored in the managed object, while the second section should have its rows sorted alphabetically by the name of its managed objects. How can I create a *single* fetched results controller that sorts different sections differently? From reading the docs for NSFetchedResultsController, in a situation with several sections, the first sort descriptor is responsible for splitting the data into sections. Fine, by I can't seem to think of a way to conditionally set the remaining sort descriptors according to which section the rows fall into. Here's part of the code I have now: NSEntityDescription* entity = [NSEntityDescription entityForName: @entity name inManagedObjectContext: self.managedObjectContext]; NSSortDescriptor* sortBySectionName = [[NSSortDescriptor alloc] initWithKey: @sectionName ascending: YES]; NSSortDescriptor* sortByIndex = [[NSSortDescriptor alloc] initWithKey: @index ascending: YES]; NSArray* sortDescriptors = [[NSArray alloc] initWithObjects: sortBySectionName, sortByIndex, nil]; NSFetchRequest* fetchRequest = [[NSFetchRequest alloc] init]; [fetchRequest setEntity: entity]; [fetchRequest setSortDescriptors: sortDescriptors]; It works, but it sorts both sections by the managed object's index. The only alternative I can think of is to create *two* fetched results controllers, one as above and the other sorting by section name and then object name (rather than index). Then, when it comes time to feed the table view, have some logic that selects data from the appropriate controller. That sounds too cumbersome. What if I had several more sections, each needing different sorting criteria? There's got to be an easier way. Thanks in advance.

You'd better not be treating your XML data as an NSString. ;-) As long as you store your data in a CDATA section, the XML API you're using should give you the ability to get the raw data for a node. Alternatively, one of the convenient properties of Base64 is that it maps your data into a range of printable ASCII characters. So you can treat the Base64 data as ASCII and write it as a string in your XML document (being mindful, of course, of the document's encoding, which is most likely UTF-8 and therefore identical to ASCII for the Base64 output range). Then read it back in as a string, convert it to ASCII, and feed the raw ASCII data into the Base64 decoding algorithm. So to maximize flexibility without involving CDATAs, here's the process I'd use: Saving: Plaintext NSString -- Plaintext NSData (UTF-8; use -dataWithEncoding:) -- Base64 NSData (ASCII) -- Base64 NSString (use +stringWithData:encoding: to create this) -- your XML document Loading: Your XML document -- Base64 NSString (UTF-16) -- Base64 NSData (ASCII characters; use -dataWithEncoding to get this) -- Plaintext NSData (UTF-16) -- NSString (again use +stringWithData:encoding:) HTH, --Kyle Sluder ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
