Construct Tk::Widget 'MultiFileSelect';
=head1 NAME
FileSelect - a widget for choosing files
=head1 SYNOPSIS
use Tk::FileSelect;
$FSref = $top->FileSelect(-directory => $start_dir);
$top - a window reference, e.g. MainWindow->new
$start_dir - the starting point for the FileSelect
$file = $FSref->Show;
Executes the fileselector until either a filename is
accepted or the user hits Cancel. Returns the filename
or the empty string, respectively, and unmaps the
FileSelect.
$FSref->configure(option => value[, ...])
Please see the Populate subroutine as the configuration
list changes rapidly.
=head1 DESCRIPTION
This Module pops up a Fileselector box, with a directory entry on
top, a list of directories in the current directory, a list of
files in the current directory, an entry for entering/modifying a
file name, an accept button and a cancel button.
You can enter a starting directory in the directory entry. After
hitting Return, the listboxes get updated. Double clicking on any
directory shows you the respective contents. Single clicking on a
file brings it into the file entry for further consideration,
double clocking on a file pops down the file selector and calls
the optional command with the complete path for the selected file.
Hitting return in the file selector box or pressing the accept
button will also work. *NOTE* the file selector box will only then
get destroyed if the file name is not zero length. If you want
yourself take care of it, change the if(length(.. in sub
accept_file.

Based on original FileSelect by

=head1 HISTORY
950621 -- The following changes were made:
1: Rewrote Tk stuff to take advantage of new Compound widget module, so
FileSelect is now composed of 2 LabEntry and 2 ScrlListbox2
subwidgets.
2: Moved entry labels (from to the left of) to above the entry fields.
3: Caller is now able to control these aspects of widget, in both
FileSelect (new) and configure :
(Please see subroutine Populate for details, as these options
change rapidly!)
4: I changed from Double-Button-1 to Button-1 in the Files listbox,
to work with multiple mode in addition to browse mode. I also
made some name changes (LastPath --> saved_path, ...).
5: The show method is not yet updated.
6: The topLevel stuff is not done yet. I took it out while I toy with
the idea of FileSelect as a subwidget. Then the 'normal' topLevel
thing with Buttons along the bottom could be build on top of it.
By request of Henry Katz <katz@fs09.webo.dg.com>, I added the functionality
of using the Directory entry as a filter. So, if you want to only see the
*.c files, you add a .c (the *'s already there :) and hit return.
95/10/17, SOL, LUCC. lusol@Lehigh.EDU
. Allow either file or directory names to be accepted.
. Require double click to move into a new directory rather than a single
click. This allows a single click to select a directory name so it can
be accepted.
. Add -verify list option so that standard Perl file test operators (like
-d and -x) can be specified for further name validation. The default
value is the special value '!-d' (not a directory), so any name can be
selected as long as it's not a directory - after all, this IS FileSelect!
For example:
$fs->configure(-verify => ['-d', [\&verify_code, $P1, $P2, ... $Pn]]);
ensures that the selected name is a directory. Further, if an element of
the list is an array reference, the first element is a code reference to a
subroutine and the remaining optional elements are it's parameters. The
subroutine is called like this:
&verify_code($cd, $leaf, $P1, $P2, ... $Pn);
where $cd is the current directory, $leaf is a directory or file name, and
$P1 .. $Pn are your optional parameters. The subroutine should return TRUE
if success or FALSE if failure.
961008 -- derf@ti.com :
By request of Jim Stern <js@world.northgrum.com> and Brad Vance
<bvance@ti.com>, I updated the Accept and Show functions to support
selection of multiple files. I also corrected a typo in the -verify code.
970116 -- adam@iset.scan.mc.xerox.com :
Added configuration option, "-selectmode", so that the programmer
can choose the selection mode of the file listbox (enabling the
multiple selection listed above). Added "Select All" button which
will select all of the files in the file listbox. The ".." component
of the directory path (along with the current directory) is now removed
if going up one level.
