Pardon me from the previous answer, you did help me a lot

After searching for the current vte development at gitlab, found the solution

get_text_range , is depreciated

Using: get_text_range_format, works perfectly

my ($string, $l) = $$self{_GUI}{_VTE}->get_text_range_format('VTE_FORM
+AT_TEXT', 0, 0, 0, 20);

Thanks a lot

Thanks for the answer

The second case, was a test. fixing to $func = sub {return 1}, returns to the first case

The only reason I mentioned is because, strangely it does not crash sending that parameter like that, which is weird for me

Accessing the source code of the get_text_range(), must be in some place of the gitlab repos for gtk from the gnome project, written in C

But in general by reading the Gtk documentation I have been able to work out everything, this is the first time I don't

This link shows the parameters to send : https://api.gtkd.org/vte.Terminal.Terminal.getTextRange.html

This link shows the function call : https://api.gtkd.org/vte.c.types.VteSelectionFunc.html

This link shows the old gnome2 vte documentation : https://gtk2-perl.sourceforge.net/doc/pod/Gnome2/Vte/Terminal.html, from where I must of the basic code that I use, everything else still works

I'm sure that I send the parameters correctly, because, I have tried a simple fixed call like this:

    # Right mouse click on VTE
    $$self{_GUI}{_VTE}->signal_connect(
        'button_press_event' => sub {
            if ($right_click_deep) {
                return 0;    # Bubble up, let VTE's original handler t
+ake care of it.
            }
            my ($widget, $event) = @_;
            my $state = $event->get_state();
            my $shift = $state * ['shift-mask'];

            if ($event->button eq 2) {
                if (!$$self{_CFG}{'environments'}{ $$self{_UUID} }{'se
+nd slow'}) {
                    return 0;
                }
                $$self{_GUI}{_VTE}->paste_primary();
                $$self{FOCUS}->child_focus('GTK_DIR_TAB_FORWARD');
                return 1;
            } elsif ($event->button eq 3 and $event->type eq 'button-p
+ress') {
                # See #209 for all this hack.
                my $handled_by_vte = 0;
                if (!$shift) {
                    $right_click_deep = 1;
                    $handled_by_vte   = $$self{_GUI}{_VTE}->event($eve
+nt);
                    $right_click_deep = 0;
                }
                if (!$handled_by_vte) {
                    $$self{FOCUS}->child_focus('GTK_DIR_TAB_FORWARD');
                    $self->_vteMenu($event);
                }
                return 1;    # One way or another, we've handled it.
            } elsif ($event->button eq 1 && $event->type eq 'button-pr
+ess' && $shift) {
                my ($w,   $h)   = $$self{_WINDOWTERMINAL}->get_size();
                my ($col, $row) = (int($event->x / $$self{_GUI}{_VTE}-
+>get_char_width()), int($event->y / $$self{_GUI}{_VTE}->get_char_widt
+h() - 1));
                print "($col,$row)\n";
                my $func = sub { return 1 };
                #my $string = $$self{_GUI}{_VTE}->get_text_range($row,
+ $col, $row, int($w / $$self{_GUI}{_VTE}->get_char_width() + 0.5), $f
+unc, my $data = undef);
                my $string = $$self{_GUI}{_VTE}->get_text_range(1, 0, 
+1, 5, $func, my $data = undef);
                #my @list = $$self{_GUI}{_VTE}->get_text();
                #print "($row,$col):@list\n";
            }

In this case I send fixed values for row,col that I know have text in that range and still I get the error

The other oddity of this is that this code crashes too

my @list = $$self{_GUI}{_VTE}->get_text();

my @list = $$self{_GUI}{_VTE}->get_text($func = udef,$data = undef);

Even when the documentation says that the 2 parameters are optional

The other thing I'm not able to find is where is the documentation for the current Vte library is I just have this old link to use as a reference https://gtk2-perl.sourceforge.net/doc/pod/Gnome2/Vte/Terminal.html
