Hi Monks,

I use the Curses::UI::Grid to display the tabular data. The window consists of a table and a few buttons to navigate the data display window to other windows.

However, when the data is displayed, the focus goes to the first row and if I use the tab to shift the focus to next UI control, it never goes to the buttons at the bottom. It just cycle thru the cells of the first row.

Here is the code to reproduce this problem:

    #!/usr/bin/env perl

    use strict;
    use warnings;
    use Curses::UI;
    use Curses::UI::Grid;

    my $debug = 0;

    # Create the root object.
    my $cui = new Curses::UI ( 
        -color_support => 1,
        -clear_on_exit => 1, 
        -debug => $debug,
    );

    create_promote_deps_window();
    $cui->set_binding( \&exit_dialog , "\cQ");

    $cui->mainloop();

    sub exit_dialog {
        my $return = $cui->dialog(
            -message   => "Do you really want to quit?",
            -title     => "Confirm",
            -buttons   => ['yes', 'no'],
        );

        exit(0) if $return;
    }

    sub create_base_window {
        my ($name) = @_;

        $cui->add(
            $name,
            'Window', 
            -border       => 1, 
            -titlereverse => 0, 
            -padtop       => 2, 
            -padbottom    => 3, 
            -ipad         => 1,
            -title        => 'CTRL-Q to quiz',
        );
    }

    sub create_promote_deps_window {
        my ($name) = @_;

        my $win = create_base_window($name);
        
        my $grid = $win->add(
            'grid',
            'Grid',
            -height       => 14,
            -width        => -1,
            -editable     => 0,
            -border       => 1,
            -process_bindings => {
                CUI_TAB => undef,
            },
            # -bg       => "blue",
            # -fg       => "white",
        );

        $grid->add_cell(
            "otp",
            -width => 10,
            -label => "OTP"
        );

        $grid->add_cell(
            "commit1",
            -width => 10,
            -label => "Commit#"
        );

        $grid->add_cell(
            "otnp",
            -width => 10,
            -label => "OTNP"
        );

        $grid->add_cell(
            "commit2",
            -width => 10,
            -label => "Commit#"
        );

        $grid->add_cell(
            "overlap",
            -width => 32,
            -label => "Overlap"
        );

        my $button_callback = sub {
            my $this = shift;
            
            my $btn_name = $this->get();
            if ($btn_name eq "Back") {
                # give up promotion and return to promote window
                $win->focus();
            }
            elsif ($btn_name eq "PromoteWithDeps") {
            }

                    -onpress => $button_callback,
                },
            ],
        );

        my @data = (
            ['HDT-10', 'e3042b0', 'HDT-7', '6741e47', 'src/tc/b.p'],

How can I customize the tab order so that user can shift the focus the buttons below the Curses::UI::Grid?

Thanks!
