The thing to do is to read the input in your loop.

example:

if you use Win32. When you make your loop, test to see if there is a message in the message queue. If there is one process it. In the message queue, you'll get all the input of the users, system calls, etc.

I suggest you go take a look at some tutorials that draws and have input.
http://nehe.gamedev.net/

This nehe's page, the tutorials are for opengl, but by looking at them, you'll understand a way to do input.
