How to connect coder to a secure wifi network

Looking for a bit of explanation as to the ability to connect coder to a wifi network. I am looking to use raspberry pi with wifi dongle to run a projector remotely. Once the pi and wifi are set up and i am able to connect directly to the pi via wifi,

How do i connect the pi to a local wireless network that is secured? i saw in a screenshot that there is a settings panel that had a wifi config button, is this the same as the wifi config as one would see on the pi desktop? Also is there some way to put the wifi config into a coder app? Or rather include the wifi config as part of a coder app that i create?
