NavDialog Plugin has obtained a new class:
Version 2.8, August 20, 2002
–added a new class: NavCallback that allows the client to sneak the user’s
temporally choices when a NavDialog is open. It also provides ways to block
the opening, to block saving or prevent creation of a new folder.
NavCallback provides additional info and manipulates a NavDialog. When
subclassed, you can block opening, or saving or block creation of a new
folder. You can monitor what files are being selected by the client, such
that when the client cancels the Navdialog, you still know what the last
folderitem was that was selected. NavCallback is a natural enhancement of
the Navigation Services the MacOS provides.
