NAME

 FileSave - a widget for choosing files

SYNOPSIS

 use Tk::FileSave;

 $FSref = $top->FileSave(-directory => $start_dir);
               $top            - a window reference, e.g. MainWindow->new
               $start_dir      - the starting point for the FileSave
 $FSref = $top->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
               FileSave.
 $FSref = $top->configure(option => value[, ...])
               At the moment, only one option is taken care of:
               -directory changes the starting directory for the
               Fileselector to the one given as value.

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.

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 :

      Option                Controls                            Default
      --------------------  ----------------------------------- ------------
        -directory          initial directory                   `pwd`
        -selectmode         mode of Files listbox               browse
        -dir_entry_label    label over directory filter entry   "Filter"
        -dir_list_label     label over directory listbox        "Directories"
        -file_entry_label   label over file entry               "File"
        -file_list_label    label over file listbox             "Files"
        -height             listbox height                      20
        -width              listbox width                       20
   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.
