using Tkx new_ttk__entry AND tk___getOpenFile

[x-lours]

Hello i'm a french newby in Perl.

I try to create a script which filter a selected file.

goal :

in a 'tk___getOpenFile' I choose my file.

in two 'new_ttk__entry' i want to write

1 / the number of the column of the filter

2 / the filter itself.

i create a new file with the rows containing the filter(1) in the column(2).

i wrote this code :

#!/usr/bin/perl -w
use warnings;
use strict;
use Data::Dumper;
use Tkx;

my ($lacolonne, @lefiltre);
my $types = [    ['CSV Files',      ['.csv']],
                ['Text Files',      ['.txt', '.text']],
                ['All Files',      '*'],];
my $fichier = Tkx::tk___getOpenFile(    -title => "Sélection du fichie
+r à filtrer",
                                        -filetypes => $types);
unless (-f $fichier) {
    print "Fichier '$fichier' non trouvé.\n";
    exit 2;
}
unless (@lefiltre) {
    my $parametre;
    saisir_2valeurs(\$lacolonne, \$parametre);
    @lefiltre = qw/$parametre/;
}
exit 3 unless ($#lefiltre);

open IN, $fichier or die "Problème à l'ouverture de $fichier E/S: $!\n
+";
while ( <IN> ) {
    my @enreg = split( /;/, $_ );
    for my $filtrage (@lefiltre) {
        if ($enreg[$lacolonne] =~ /$filtrage/) {
            open OUT, ">> filtrer_fichier_$filtrage.txt" or die "filtr
+er_fichier_$filtrage.txt E/S: $!\n";
            print OUT $_ ;
            close OUT;
        }
    }
}
close IN;

sub saisir_2valeurs {
use Tkx;

    my ($saisie1, $saisie2) = @_;

    my $mw = Tkx::widget->new(".");
    $mw->g_wm_title("Saisir le type");
    my $frm = $mw->new_ttk__frame(-padding => "2 3 12 12");
    $frm->g_grid(-column => 0, -row => 0, -sticky => "nwes");

    my $e_colonn = $frm->new_ttk__entry(-width => 9, -textvariable => 
+$saisie1);
    $e_colonn->g_grid(-column => 2, -row => 1, -sticky => "we");
    my $e_filtre = $frm->new_ttk__entry(-width => 9, -textvariable => 
+$saisie2);
    $e_filtre->g_grid(-column => 2, -row => 2, -sticky => "we");
    my $cb = $frm->new_ttk__button(-text => "Valider la saisie", -comm
+and => sub { $mw->g_destroy; });
    $cb->g_grid(-column => 3, -row => 3, -sticky => "w");

    $frm->new_ttk__label(-text => "Le numéro de colonne du filtre :")-
+>g_grid(-column => 1, -row => 1, -sticky => "e");
    $frm->new_ttk__label(-text => "Le filtre à extraire      (qw) :")-
+>g_grid(-column => 1, -row => 2, -sticky => "e");

    foreach (Tkx::SplitList($frm->g_winfo_children)) {
        Tkx::grid_configure($_, -padx => 5, -pady => 5);
    }
    $e_colonn->g_focus;
    $mw->g_bind("<Return>", sub { $mw->g_destroy; });

    $mw->g_tkwait_window;

    Tkx::MainLoop();

    print "dans la fenetre $saisie1,$$saisie1; $saisie2,$$saisie2.\n";
}

but i can't write in any of the 2 'new_ttk__entry' !

Why ?

they seem to be disabled or in readonly mode, i don't know ...

can anyone explain me what is the problem ? and of course how to solve it ;-)

best regards

PS

with one 'tk___chooseDirectory' and one 'new_ttk__entry', i cant write in the 'new_ttk__entry'.

Hello i'm a french newby in Perl.

What are the implications of this? I mean le implicationes?

update: I was right $lacolonne, its in like la french :)

update: pod lines newline after commands paragraphs, as in =head1 NAME\n\nNAME - the is le

If you use scriptdist it will insert a template pod of the right form, like

=head1 NAME

$script_name - this script does something

update: Oh, so it prompts for a csv file, i give a random one, then prompts something in french, and yes, i see the problem, can't write in the entries.

This works

#!/usr/bin/perl --
use strict; use warnings;
use Tkx;
local  $Tkx::TRACE=64;

my $the_shining = "Here's Johnny! 0";
my $mw = Tkx::widget->new(".");

my $b = $mw->new_ttk__button(
    -text => 'Hello, world',
    -command => sub {
        $the_shining =~ s/(\d+)/$1+1/e;
        return;
    },
);

$b->g_pack;

my $e = $mw->new_ttk__entry(
    -width => 9,
    -textvariable => \$the_shining,
);

$e->g_pack(
    -expand => 1,
    -fill => 'both',
);

Tkx::MainLoop();

__END__

For CSV, you should use one of Text::CSV// Text::CSV_XS/Text::xSV

See also tkx grid example and tutorial

update: the entries in your program can get focus if your program loses focus, then gains focus again. I have no idea what is at work here :/ but you can do this programatically

    $mw->g_wm_withdraw();
    $mw->g_wm_deiconify();
    Tkx::MainLoop();

For future reference, esp GUI problems, its best to trim all file operations from your program :) See How do I post a question effectively?

Thanks a lot !

you find the trouble : loosing focus. your code is efficient and is enough for me.

$mw->g_wm_withdraw();
$mw->g_wm_deiconify();
Tkx::MainLoop();

also thanks for the tutorial.

i was looking for some ;-)

i found this code :

Tkx::focus(-force => $mw);

which works well also. (when you know what your are searching for ...)
