6 Tk::FileSelect - a widget for choosing files
7
9 use Tk::FileSelect;
10 $FSref = $top->FileSelect(-directory => $start_dir);
12 $top - a window reference, e.g. MainWindow->new
13 $start_dir - the starting point for the FileSelect
14 $file = $FSref->Show;
15 Executes the fileselector until either a filename is
16 accepted or the user hits Cancel. Returns the filename
17 or the empty string, respectively, and unmaps the
18 FileSelect.
19 $FSref->configure(option => value[, ...])
20 Please see the Populate subroutine as the configuration
21 list changes rapidly.

24 This Module pops up a Fileselector box, with a directory entry on top,
25 a list of directories in the current directory, a list of files in the
26 current directory, an entry for entering/modifying a file name, an
27 accept button and a cancel button.
28 You can enter a starting directory in the directory entry. After
30 hitting Return, the listboxes get updated. Double clicking on any
31 directory shows you the respective contents. Single clicking on a file
32 brings it into the file entry for further consideration, double
33 clocking on a file pops down the file selector and calls the optional
34 command with the complete path for the selected file. Hitting return
35 in the file selector box or pressing the accept button will also work.
36 *NOTE* the file selector box will only then get destroyed if the file
37 name is not zero length. If you want yourself take care of it, change
38 the if(length(.. in sub accept_file.

47 950621 -- The following changes were made:
48 • Rewrote Tk stuff to take advantage of new Compound widget module,
49 so FileSelect is now composed of 2 LabEntry and 2 ScrlListbox2
50 subwidgets.
51 • Moved entry labels (from to the left of) to above the entry fields.
53 • Caller is now able to control these aspects of widget, in both
55 FileSelect (new) and configure :
56 (Please see subroutine Populate for details, as these options
58 change rapidly!)
59 • I changed from Double-Button-1 to Button-1 in the Files listbox, to
61 work with multiple mode in addition to browse mode. I also made
62 some name changes (LastPath --> saved_path, ...).
63 • The show method is not yet updated.
65 • The topLevel stuff is not done yet. I took it out while I toy with
67 the idea of FileSelect as a subwidget. Then the 'normal' topLevel
68 thing with Buttons along the bottom could be build on top of it.
69 • By request of Henry Katz <katz@fs09.webo.dg.com>, I added the
71 functionality of using the Directory entry as a filter. So, if you
72 want to only see the *.c files, you add a .c (the *'s already there
73 :) and hit return.

76 •
77 Allow either file or directory names to be accepted.
80 • Require double click to move into a new directory rather than a
82 single click. This allows a single click to select a directory
83 name so it can be accepted.
84 • Add -verify list option so that standard Perl file test operators
86 (like -d and -x) can be specified for further name validation. The
87 default value is the special value '!-d' (not a directory), so any
88 name can be selected as long as it's not a directory - after all,
89 this IS FileSelect!
90 For example:
92 $fs->configure(-verify => ['-d', [\&verify_code, $P1, $P2, ... $Pn]]);
94 ensures that the selected name is a directory. Further, if an
96 element of the list is an array reference, the first element is a
97 code reference to a subroutine and the remaining optional elements
98 are its parameters. The subroutine is called like this:
99 &verify_code($cd, $leaf, $P1, $P2, ... $Pn);
101 where $cd is the current directory, $leaf is a directory or file
103 name, and $P1 .. $Pn are your optional parameters. The subroutine
104 should return TRUE if success or FALSE if failure.
105 961008 -- derf@ti.com :
107 By request of Jim Stern <js@world.northgrum.com> and Brad Vance
108 <bvance@ti.com>, I updated the Accept and Show functions to support
109 selection of multiple files. I also corrected a typo in the -verify
110 code.
