New tooltip system?

Some of us know Diego Kerejeta. He retired some time ago, but he never stopped working on a really good tooltip system for Xbase++ applications. A few days ago, he released the attached code and sample "for free", and he explicitly linked this to permission to use and distribute the code. It looks great to me.
I would try by myself to adapt this for eXpress++, but maybe it would be a little easier if Roger takes a look.

This is how it looks:

Diego released a new version, and he added this comment:
I have just modified the XbpToolTip class, simplifying it a lot. For me, this is the recommended version to use.
There are at least two ways to work with tooltips:
- Direct storage inside the tooltip control (the new version).
- Delegated loading/display through LPSTR_TEXTCALLBACK + WM_NOTIFY + TTN_GETDISPINFOA (the previous version).
The first approach has the advantage of being much simpler, more straightforward, and self-contained (there is no need to modify anything in the XbpDialog it is attached to).
The second approach may be intended for dynamic text usage, where the text can change each time the tooltip is displayed. In Xbase++, it is slower, more complex, and requires changes in the parent XbpDialog (handling notifications via WM_NOTIFY).
Both approaches are equally functional and properly integrated into Xbase++ (or at least I believe so), although I personally prefer the new one. At least, it is the one I will use for maintaining our applications.
