Re: Gtk2::Notebook with large tabs

[thanos1983]

Hello Anonymous Monk,

Since I am not familiar with Gtk2 I can not really help you. But I did not searched online and I came up with $notebook->set_tab_border ($border_width) I think this is probably what you are looking for. You can find other adjustments that you might be interested Gtk2::Notebook.

Also if you have some time I would suggest to read also the new Perl module Gtk3s it has some extra features that you might be interested.

Give it a try and reply to your question if you get more information(s) / solution(s), so other can benefit from.

Any way as I said I have never used the module before so I hope my answer helped you or at least pointed you to the correct direction.

Hey thanos1983, thanks for your suggestion!

It suddenly occured to me, while fiddling with ->set_tab_border(), that it might be the stock icon that was preventing the label from becoming smaller.

Sure enough, removing the stock icon altogether reduces the tab's size dramatically. Using a smaller stock icon is also effective:

$noteBook->set_tab_border(0);
$button->set_image(Gtk2::Image->new_from_stock('gtk-close', 'menu'));

Here's the corrected script:

#!/usr/bin/perl
package biglabel;

use strict;
use diagnostics;
use warnings;

use Gtk2 '-init';
use Glib qw(TRUE FALSE);

# Create the window
my $window = Gtk2::Window->new();

$window->set_title('Notebook');
$window->set_position('center');
$window->set_default_size(800, 500);
$window->set_border_width(5);
$window->signal_connect (destroy => sub { Gtk2->main_quit; });

# Add a VBox with a VPaned, containing a notebook at the top and an en
+try at the bottom
my $vBox = Gtk2::VBox->new(FALSE, 0);

my $vPaned = Gtk2::VPaned->new();
$vPaned->set_position(400);
$vBox->pack_start($vPaned, TRUE, TRUE, 0);

my $noteBook = Gtk2::Notebook->new();
$noteBook->set_scrollable(TRUE);
$noteBook->can_focus(FALSE);
$noteBook->set_tab_border(0);
$vPaned->add($noteBook);

my $entry = Gtk2::Entry->new();
$entry->can_focus(TRUE);
$vPaned->add2($entry);

# Add three tabs to the notebook
for (my $num = 0; $num < 3; $num++) {
    
    my ($buffer, $tabNum) = openTab($noteBook);
}

# Open the window
$window->add($vBox);
$window->show_all();

Gtk2->main();

sub openTab {
        
    # Create a tab in the notebook, containing a textview
    
    my ($noteBook) = @_;
    
    # The vertical packing box contains only a textview
        my $vBox = Gtk2::VBox->new(FALSE, 0);

        # The horizontal packing box is used as the tab's label (in pl
+ace of a Gtk2::Label)
        my $hBox = Gtk2::HBox->new(FALSE, 0);

        my $label = Gtk2::Label->new('Hello world');
        $hBox->pack_start($label, FALSE, FALSE, 0);

        my $button = Gtk2::Button->new();
        $button->set_image(Gtk2::Image->new_from_stock('gtk-close', 'm

        $hBox->pack_start($button, FALSE, FALSE, 0);

        $label->show();
        $button->show();
        my $tabNum = $noteBook->append_page($vBox, $hBox);

        # Add a textview to the tab
        my $frame = Gtk2::Frame->new(undef);
        $frame->set_border_width(0);

        my $scroll = Gtk2::ScrolledWindow->new(undef, undef);
        $scroll->set_shadow_type('etched-out');
        $scroll->set_policy('automatic', 'automatic');     
        $scroll->set_border_width(0);

        my $textView = Gtk2::TextView->new();
        my $buffer = Gtk2::TextBuffer->new();
        $textView->set_buffer($buffer);
        $textView->set_editable(FALSE);
        $textView->set_cursor_visible(FALSE);   # Invisible cursor
        $textView->can_focus(FALSE);
        $textView->set_wrap_mode('word-char');  # Wrap words if possib
+le, characters if not
        $textView->set_justification('left');

        $scroll->add($textView);
        $frame->add($scroll);
        $vBox->pack_start($frame, TRUE, TRUE, 0);

        $window->show_all();

        # The new tab should be the visible (current) one
        $noteBook->set_current_page($tabNum);

    return ($buffer, $tabNum);    
}

Hello Anonymous,

I am glad that you got the answer to your question that you where looking for even through alternative solution. A different point of view is always good. Just keep on trying failing and happy coding... :D .
