Hi!
I need to create an Application with the following functionalities:
The User can drag&drop image files onto the application window and then
these are displayed in a kind of list as thumbnails with "edit" and
"delete" buttons and a short info text about the image format next to
the thumbnails.
I can pretty much enable NSTableView to do what I want, I am not yet
too familiar with subclassing NSCell to display (and get to work) 2
buttons in one column, but I hope I will learn that quickly enough.
Given the somewhat nonstandard cell formatting, I wonder whether it
would be more reasonable to create an NSMatrix + NSScrollView? I assume
though, that I should go with the NSTableView, what is your suggestion?
My second question concers the thumbnails. As of right now, I have an
array with the image paths and simply read out the images into the
NSImageCell, so they are resized automatically. It seems though, that
this produces a lot of work for the processor/memory. I cannot scroll
the images as quickly as e.g. in Preview.app, as my computer seems to
have a lot of work dealing with the (full-size?) images and rescaling
them (everytime?).
Since my application is supposed to go with maybe more than 100 jpgs,
this behavior is not wanted. What would you suggest to do? There has to
be a more efficient way to deal with thumnails...
Sorry for so much text and thanks in advance :-)
Bye,
Michael
