An NSImageCell needs an image. Why would you bind an NSDictionary to
it?
I have a column with image + text as well , so I took advantage of
setting object value as Dictionary
and in the drawWithFrame:(NSRect)cellFrame inView:(NSView
*)controlView in NSTextFieldCell ,
I got the objectValue ( i.e., dictionary ) and done the necessary
drawing + text display
I tried following the same approach here as well
And why would you call an ivar holding a dict previewID and not
previewDict?
I have Framework which returns details of image in Dictionary format
( like URL etc )
I am trying something like , lazy loading of images , because i
have very large number of images
I load image only when it is required
And why do you call that sometimes PreviewID and sometimes previewID?
It just a identifier ( but binding value is dictionary )
My ultimate question is , can't I take care it like the
NSTextFieldCell case ?
Thanks

Hi all,
w.r.t one of my earlier post ( subject : Design for showing
ridiculously huge number of images in Table View )
I have a table column(With ImageCell) to be filled with images , I
have a NSTreeController which has dictionary for this image
( dictionary has few details , using which I fetch the images )
after binding this column with the said dictionary and running the
build , in run log , I see complaints, that it is expecting an
NSImage .... and hence image don't show up
instead using a NSTextField cell , I could draw the image
myself , I don't think its a good idea because I need to show
images proportional to their sizes
am I doing a blunder here ?<Picture 5.png> , previewID has
dictionary with it. every other column is fine with the binding ,
except this imageColumn
Should I work at cell level binding ? like cell's Controller Key
with 'selection' ??
I need to show a image-tool tip when I hover this image .... but
that is future requirement and it can wait for now...
Thanks in Advance
