Re: Fwd: bug on TextBuffer and TextView

[Mario Kemper <mario kemper googlemail com>]

Here is a simple example that works (I've used most of your code
snippet).

Maybe it would be useful to attach an example that shows the
misbehaviour you've described.

-------------------Example-----------------------------------
#! /usr/bin/perl -w 

use Gtk2 '-init';

my $window = Gtk2::Window->new('toplevel');

my $view = Gtk2::TextView->new();
my $buffer = $view->get_buffer();
$view->set_size_request(200,200);
$view->set_editable (FALSE);
our $textmark = $buffer->create_mark('end_mark',
$buffer->get_end_iter,FALSE);
my $scrolls = Gtk2::ScrolledWindow->new();
$scrolls->set_policy('automatic','always');
$scrolls->set_shadow_type('in');
$scrolls->add ($view);

my $button = Gtk2::Button->new('Insert text');
$button->signal_connect('clicked' => sub{

        #printing the output on textview
        my $text_tag = $buffer->create_tag(undef,'font',"Sans Italic
12",'foreground','#680000');
        $buffer->insert_with_tags($buffer->get_end_iter,"<Test>\n",$text_tag);
        $buffer->insert ($buffer->get_end_iter,'Another little test');
        $view->scroll_mark_onscreen($textmark); 
        
});

my $vbox = Gtk2::VBox->new(0, 0);
$vbox->pack_start_defaults($scrolls);
$vbox->pack_start ($button, 0, 0, 0);

$window->add($vbox);

$window->show_all;

Gtk2->main;

0;
-------------------Example-----------------------------------
