Hi !
After reading all the discussions around thumbnail matrices, I
decided to try to implement it with bindings.
I have in my myDocument (fileOwner) a mutable array of dictionaries,
with one key 'image' which holds
an NSImage.
I created an arrayController that binds to fileOwner._thumbsArray
(the array of dictionaries).
My NSMatrix's content is bound to the controler with the model key
path set to 'image'.
I load each NSImage with [[NSImage alloc] initWithContentsOfFile:
curFile]
then, create a dictionary, add that image to it, then add the dico to
the array :
NSImage *tmpImage = [[NSImage alloc] initWithContentsOfFile: curFile];
NSMutableDictionary *newDico = [NSMutableDictionary
dictionaryWithObjectsAndKeys:tmpImage, @"image", newCell, @"cell", nil];
[self insertObject: newDico in_thumbsArrayAtIndex:[self
countOf_thumbsArray]];
but, as soon as I do the insertObject, I get the following error :
NSImageCell's object value must be an NSImage.
I logged everythings, and the image is really an NSImage.
(The reason I put the image inside a dictionary is because I read a
hint here about kvc compliance and
dictionaries, I tried with a 'pure' array of NSImages and I had the
same errors).
I really don't see what I'm doing wrong !
any help would be appreciated ^_^ thanks !
PS I also read about reducing the image's size for thumbs, but I keep
this for when the first part works...
