@Martin F

Do u think it's ok way: build column-selection(Alt-Drag) ABOVE
existing multi-carets. All programs: column-sel is new thing ,where
editor draws column block and handles it as column. Why not: don't
make new thing but use existing multicarets for this-- just make N carets
for all lines of block and make selections for them? it will look like old approach.
Less code. No need to make new code for AltDrag and utilize old

This is really probably a personal decisions. I dont know how different editors handle different selections.

AFAIK:
Multiple selections (such as you propose) are copied to the clipboard, by joining them with a new line (though I really do not know if that always applies).
Thus when pasted, I would expect them to insert new lines.

Column mode selection, is copied in a special mode, that, if pasted inserts into existing lines. They do not insert new lines.

But I do not know how many editors do this.

It seems such copy/paste breaks that idea. I dont want to paste incorrect, so i stay with usual idea.. 
I've done mul-selections: make selections with Ctrl+Drag

Code: [Select]
procedure TATSynEdit.UpdateScrollbarVert;
var
  si: TScrollInfo;
begin
  FillChar(si{%H-}, SizeOf(si), 0);
  si.cbSize:= SizeOf(si);
  si.fMask:= SIF_ALL;// or SIF_DISABLENOSCROLL; //todo -- DisableNoScroll doesnt work(Win)
  si.nMin:= FScrollVert.NMin;
  si.nMax:= FScrollVert.NMax;
  si.nPage:= FScrollVert.NPage;
  si.nPos:= FScrollVert.NPos;
  SetScrollInfo(Handle, SB_VERT, si, True);
end;


problem. If i uncomment 'or SIF_DISABLENOSCROLL' then I expect that scroll won't hide but will be shown on small text. it's ok - Linux, it's broken- Win32, on Win i see scroll hidden !

What to do on Win?

It works in SynEdit (at least win), the flag is set, and the scrollbar is shown disabled if needed. (and if SynEdit is set to do so)

how to group Undo items, via "Group undo" option? e.g. I type text, then Enter, then move-caret, then type again... and what are groups of undo?

In SynEdit items are grouped if:

- they have the same command: both ecChar, or both ecNewLine, or both ecDeleteWordLeft ...
- the caret start pos, of the 2nd item is the caret end pos of the 1st

But there could be different rules, for example, instead of checking the caret pos, one could check, that no other action (e.g. caret move) happened in between.

I have no idea how other editors do this.

Delphi or some ide, has featire-- undo jumps to last change,only next undo undoes this change.
Synedit has it?

No.

But thanks for explaining it. I had never been able to figure out the logic, about what Delphi actually does on undo.

Now I at leas get it, thanks to your post.

Easy to implement though, but no priority.

I am not aware of any "standard" how the *extra* info is stored in the clipboard. SynEdit invents its own.

That is, 2 parts a copied.
1) the text, normal format for any text editor.
2) the extra info (i.e. a flag, that this is column mode data)

for 2 clipboard has AddFormat(). etc..

Code: [Select]
  SYNEDIT_CLIPBOARD_FORMAT_TAGGED = 'Application/X-Laz-SynEdit-Tagged';

The same is used to keep folds in copy and paste.

SO column mode works only synedit to synedit. Other editors only see the text.

thank. I ll see SE code how to.
Btw, maybe interesting to u: i made ColBlock as mul-selections (as I wrote before), with flag "we have rect [x1,y1,x2,y2]" (flag is used if needed to copy)
