Comparing current page's id to post's page id?

I have the following loop to add links for sub pages in one of my sections. I now want to add the link so, that if you are already on a page it adds a disabled link, so you can’t click on it again. What I am struggling with now is finding a way to test if the current page’s id is equal to the id of the linked to page. Here is what I have so far, but it doesn’t work like I want it:

if ($queryObject->have_posts()) {
	while ($queryObject->have_posts()) {
		$queryObject->the_post();

		if ( is_page() == the_ID() ) {
			echo '<li>; the_title(); echo '</li>';
		} else {
			echo '<li><a href="'; the_permalink(); echo '">'; the_title(); echo '</a></li>';
		};

	}
}

I have also tried both of the following:

if ( is_page() == $queryObject->the_post()->ID ) {

if ( is_page() == $queryObject->post->ID ) {

Thanks a lot for any help with this!
