      <P>Splitter windows have been a popular UI element since Explorer =
debuted=20
      in Windows 95, with its two-pane view of the file system. MFC has =
a=20
      complex and powerful splitter window class, however it is somewhat =

      difficult to learn how to use, and coupled to the doc/view =
framework. In=20
      Part VII, I will discuss the WTL splitter window, which is much =
less=20
      complicated than MFC's. While WTL's splitter implementation does =
have=20
      fewer features than MFC's, it is far easier to use and extend.</P>
      <P>The sample project for this part will be a rewrite of <A=20
      =
href=3D"http://www.codeproject.com/clipboard/clipspy.asp">ClipSpy</A>, =
using=20
      WTL of course instead of MFC. If you're not familiar with that =
program,=20
      please skim over the article now, as I will be duplicating the=20
      functionality of ClipSpy here without providing in-depth =
explanations of=20
      how it works. This article's focus is the splitter window, not the =

      clipboard.</P>
