How to specify links to open internal pages in quicklinks

Hi

I am developing a component for having quick links in which i can have both Internal and external links. External links are working fine. I am facing problem with internal links.

While adding internal links, I am specifying (by browsing) the target as the WPC Page which should be opened in the same window on selecting that link in the dropdown box. But I am not getting the page opened. Please let me know if there is any API using which i can get the URL which is associated with that page and which can be used for opening the target page in the same page.

Regards
