How to store/load workspaces?

I'm new to this toolkit, please bear with me.

I searched the 'documentation' and this forum, but I did not find anything.

Is there somewhere an explanation/example which shows how to store the window position of the main frame window, the docking pane layout, the toolbars and other UI elements in a archive / file? I cannot store data in the registry

When I search the samples, I find many areas where apparently parts of the windows / docking bars are saved.

But there is no documentation what all these methods do, when to use them, how to use them, and in which sequence.

I understand that the programmer who has created these examples did know how to use all these methods, but neither the source code comments not the toolkit reference contain any additional information.

I see that this toolkit is very powerful, but the lack of documentation prevents us from using all this power.

I've found an example which seems to use CXTPPropExchange to store all this stuff in an archive. But the method it uses is about 50 lines long, calls dozens of toolkit methods, and all without a single comment.

Where in the documentation is all this explained, which classes work together, when to store what?

What I have in mind is to allow me users to store "workspaces", and to load them later from files.

Any help and tips appreciated.
