To any S-Plus programmers...
I'm trying to write a customised GUI at the moment, including a dialog box
which will allow me to select a file with a specific extension (not one of
the usual ones - the file is ASCII, but the extension denotes the
application which produced it, and I don't want to change it) from either
my hard disk or the network. To do this, I need to be able to change both
the drive and the directory that I'm looking in, in addition to specifying
the extension I want.
Presumably this can be done by using the same tools as are used in the
File|Import Data dialog - but I can't find these in the manual. None of
the DialogControl items listed for guiCreate("Property") seems to serve the
purpose, unless what I want is a list box whose default values are set by
drive/directory changes - but this seems unexpectedly complicated for what
should be a very common requirement - and in any case, I don't know how to
change a working directory in S-Plus.
Which tools should I be using, and what are their various options?
As a separate question, is it possible to inspect the S-Plus script which
generated the File|Import data dialog box? I'm sure I'd learn a great deal
about programming in S-Plus very quickly if I had access to such things.
Many thanks for any help that anyone can offer.
