There is no "OnMoved" in TPairSplitter (at least I can't find one).
It would require to have a control for the splitter object too (which does not exist either).

That means that I need to switch to TSplitter some day anyway,
if new WidgetSets are not supported anymore.

Well, if I look into the code there are lots of TSplitter controls used in TPairSplitter.
To me it looks that it's all based on TSplitter.
Though I don't know all the details...
