How can we Implement Page Object Model in test complete like how we do in Selenium?

Here's a previous thread that may be of some help

Hi,

Actually, NameMapping and Aliases in TestComplete provide a kind of Page Object Model, but supersedes it as for me.

Nothing prevents you to code POM as you used to do in Selenium, but my preference is Aliases.
