changing font size

[diggitydoggz]

Hey guys. For a project that I'm doing just for practice, I am making a very simple notepad type application. In my frame I have a little text field at the bottom which the user can use to change font size. I want to make it so that the font in the textArea changes to whatever value I put into the font textfield without me having to click on any buttons - just typing in a new value should trigger the font change. I tried using a standard actionListener on the text field but it didn't work - I've been unable to discover a method to do this. Does anybody have thoughts on how I might be able to pull this off?
