[PHP-GTK-DEV] drag-data-received - get_path_at_pos(x,y) wrong result?

I´ve the some problems with my program like mentioned by kksou some days ago.

http://www.kksou.com/php-gtk2/articles/use-drag-and-drop-to-shift-rows-in-a-GtkTreeView---Part-1.php

I´ve connected the signal "drag-data-received" for drag n DROP.

If i use the x and y variable in the callback to get the drag destination
row with $pathData = $widget->get_path_at_pos($x, $y); i got an wrong
position. Like kksou mentioned, i have to substract 1... that works... but
what, if i want to drag to the end of the list (last entry)? This isnt
working, because i substract 1 by default.

In the documentation i´ve found no hint for this.

	$treeView->connect('drag-data-received', array($this, 'onDrop'));

	public function onDrop($widget, $context, $x, $y, $data, $info, $time){
		
		# get the destination
		$pathData = $widget->get_path_at_pos($x, $y);
		
		$path = reset($pathData[0])-1;
		if($path < 1) $path = 0;

		# QUESTION - How to handle the drop on last entry?
		# i cannot access this, because i substract 1 by default!
		
		$selection->select_path($path);
		list($model, $iter) = $selection->get_selected();
		if ($iter === null) return false;
		$destCompoundId = $model->get_value($iter, 5);

		// aso......
		
	}

Best regards,
Andreas
