How to show post from a particular category widget

Consider downloading and installing Otto’s PHP Code Widget.

Then put this in one of those widgets:

<?php
    $args=array(
      'cat' => 1,
      'posts_per_page'=>5,
      'caller_get_posts'=>1
    );
    $my_query = new WP_Query($args);
    if( $my_query->have_posts() ) {
      echo '5 recent Posts from category 1';
      while ($my_query->have_posts()) : $my_query->the_post(); ?>
        <p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>
       <?php
      endwhile;
    } //if ($my_query)
  wp_reset_query();  // Restore global post data stomped by the_post().
?>
