Can I use code folding in "case of" statement ?

You may have to use a recent Lazarus Snapshot.

Check environments options / editor / code folding. There is an entry
for case. (folds the whole case ... end block)

Individual case items inside the block are usually begin...end blocks
(or one liners). If they are begin end blocks, then they can be
folded.

Thanks for help.
I've another problem with saving folding state. When I close lazarus
folding state doesn't save.But sometimes it saves. I don't know when
and why ?!

Which version / revision of lazarus are you on?

There where fixes about 1 or 2 month back.

also check what is in the project.lps (or lpi, if you don't do lps).
(lps may be in your user dir, subfolder lazarus/projectsession )

Is the unit listed only once? does it have some (unreadable)
foldstate?.

I don't have lps, inside lpi I've
Code: [Select]<FoldState Value=" T0YR2V"/>My lazarus/projectsession in
user dir is always empty.
But I found that, when I go to Project Options and change something
and then compile,save, close lazarus then folding state saves ok.

Ah.  simply folding a block of code, does not mark the session as
modified. So it doesn't get saved.

- If you switch tabs from one editor to another, that should set the
session to modified
- I am not sure, if moving the caret does.

If anything has marked the session as modified, or if you force saving
it (save project, should do that, I believe) then this should always
include saving an updated fold-info.

Yes, switch tabs and everything is ok. Thanks
