Howdy:
New day, new problem. There's been a fair amout of traffic on the list
about NSTableView and NSMatrix lately, so why not add some more?
Like other folks out there, I'm working on adding support for browsing
images in a user's iPhoto Library (are you listening Apple, we need
public API's for doing this, along with accessing media from the other
iLife apps).
At any rate, I want to create a "contact sheet"-like display of images.
I've been able to do this using an NSTableView, which was easy enough
to do. However, as others have recently pointed out, if you want to
isolate a single cell, you're kind of SOL. The prevailing wisdom seems
to be to use an NSMatrix, which I've been working on, but I'm having
trouble.
Since the number of image cells will vary, I need to programmatically
create the NSMatrix (or in my case, a subclass). I created a method to
add the necessary rows based on an array of URL's. (using insertRow:
withCells). So far, so good, but nothing displays, even after calling
displayIfNeeded.
Bummer.
Did I do something wrong in IB? I dragged a view onto my window, then
changed its class to my NSMatrix subclass. Should I simply create an
NSView subclass and add my matrix as a subview?
As always, any help greatly appreciated.
John
