mp3filemanager.c(updated Sun Oct 14 21:25:36 2007)

/*
* This is a Gtk2 replacement for the MP3FileManager program shipped
* with the Sony NW-S23. It currently needs the following things
* fixed (X marks the ones I've fixed):
*
* X dropping folders at specific positions doesn't work; they always
* get appended to the end of the folder list. You can move 'em
* around once they're on the device, though.
* X changes are synced to the device far too often, and the syncing
* is a huge kludge that involves deleting the entire track/folder
* list, syncing that, then rebuilding the new list from
* scratch. Mostly this is because I need to add a few more hooks to
* mple.c
* X doesn't delete mp*.dat files when tracks are deleted from the
* UI. The index entries *are* deleted, so the mpdat files won't
* play, though.
* * Delete All button does nothing
* * You can't select more than one thing at a time from the
* list. This is a serious pain if you're trying to make bulk
* changes, such as moving a half-dozen tracks. This can't be fixed
* without subclassing, see below.
* * Delete All and Delete both have confirm dialogs in the Windows
* version.
* * The file transfer stuff needs a little fixing - the main window
* should be disabled; this is done with - I think - an
* application-modal window on Windows. A better idea would be to
* thread the transfer process so you could keep adding files while
* the current transfer is in progress.
* * You can't drop a deep directory structure on it and expect it to
* do something useful. Windows will collapse a Band/Album/Mp3.mp3
* filename into Folder "Band Album", Track Mp3.mp3
* X Files should be listed by the mp3 filename, not the mp3 title.
* * The windows version doesn't use a progress bar for
* transfers. While I like the progress bar, it does mean that the
* status bar is only half as wide as it should be.
* * It would be nice if I could handle any URI that drag-and-drop
* throws me; at the very least, dragging a URL from firefox into
* the gadget would be cool.
* * Context menu is broken
* * Context menu should allow you to edit the metadata of a file
* X The device path is hardcoded.
* * Mount/Unmount device would be neat
* * dropping is still not quite right
* - dropping a file at the end of the device
* - dropping a file onto a folder prepends instead of appends
*
* And internally;
* * the code is full of memory leaks. I did a dry-run with valgrind,
* but there's so much noise from Gtk and X that I gave up.
* * Globals. I hate globals. I hate hate hate hate them.
* * Might be smart to isolate the unix-specific stuff if I'm going to
* try building this on Windows at some point. There are probably
* glib functions to help me.
*
* The code is, in general, pretty horrible, in part because I'm
* trying to force the default GtkTree stuff to do things it's not
* really meant to do. At some point I need to learn how to subclass
* the GtkTreeStore so I can add on the bits I need, such as better
* drag/drop, edit on button-click rather than button-press, etc.
*
* The other reason the code is horrible is that I've not done any
* serious Gtk work before, and it's not exactly intuitive. I keep
* finding useful glib functions after I've spent half an hour writing
* equivalent code, too. Henry Spencer would be proud...
