Excerpt of article text...
I must be getting old -- I remember when the term "web browser" was a novelty. Today web browsers are so standard it's not uncommon to have one inside another application.
For example, many help systems will use HTML-based help files and the help viewer application (or built-in viewer) is essentially a mini-web browser. Other programs need to link you to the web for viewing information and sometimes it is better (interface-wise) to do that in an integrated fashion rather than sending the user to their default browser.
How is this done, you ask? Isn't rendering HTML a lot of overhead for an application? Well, there's not much overhead because most modern operating systems today already feature a web-browser engine as part of the OS. Therefore it's easy for other applications to simply call that engine when some HTML needs rendering.
REALbasic lets you do this easily with its HTTPViewer control. This is a seemingly basic control, but it has surprising power and usefulness. Today we'll explore how to incorporate it into your own application.
