Howdy-- I've been writing as my main project a simple MIDI editor off and on for the past year or so. As my programming skills improve, I tend to go back and rewrite certain parts of the editor.
Right now, I'm doing a major rebuild of the editor interface (the part where the user adds/clicks/drags/deletes notes) and I'm coming to a conceptual question/problem that I'd like to ask folks on the list, and it regards how to manage objects whose order can be changed at the whim of the user. Currently, I manage notes (a custom class) in a set of arrays, everything from all the notes themselves, selecting, deselecting, etc. This is fine as long as the notes remain in their sequential order, and is particularly handy when it comes to playing and writing binaries of the song. It seems to work fine so far, but I'm hitting some roadblocks when it comes to selecting and deselecting multiple objects that I'm pretty sure are due to them being held in an array. Since the order of the notes and their selection can changed by the user, I'm thinking that a Dictionary might be the way to go. The only part that's truly fuzzy to me is how to put them all into sequential order when the user wants to play and save their files. Beyond that, the Dictionary seems to be the way to go with object management in this application. Before I get elbow deep into changing over my code, I thought I'd ask the group if that seems like the way to go, how they would approach it, maybe there's a more advanced approach I'm not aware of, etc. Thanks! -- Philip Regan [EMAIL PROTECTED] http://homepage.mac.com/pregan REALBasic 2005r4, Applescript Mac OS 10.3.9 _______________________________________________ Unsubscribe or switch delivery mode: <http://www.realsoftware.com/support/listmanager/> Search the archives of this list here: <http://support.realsoftware.com/listarchives/lists.html>
