caret position is not reverted by Undo in splitted ui-tab

[Alexey-T]

make new tab, split it, and type in the right part.

call 'undo' also in the right part -> text undoes OK but caret stays at old position in the right part (at line 4, in the middle column).

these steps?

[Alexey-T]

what if you run 'Undo' by a hotkey, instead of Cmd Palette?

[MiroslavMatas]

the same like on the video - doesn't matter if Undo by hotkey and/or by Cmd…

Hmmmm. I reproduced it also on macOS. will check on Win32 later.

current code in atstrings.pas has events to change carets/markers/attribs during Undo action

    property OnGetCaretsArray: TATStringsGetCarets read FOnGetCaretsArray write FOnGetCaretsArray;
    property OnGetMarkersArray: TATStringsGetMarkers read FOnGetMarkersArray write FOnGetMarkersArray;
    property OnGetAttribsArray: TATStringsGetAttribs read FOnGetAttribsArray write FOnGetAttribsArray;
    property OnSetCaretsArray: TATStringsSetCarets read FOnSetCaretsArray write FOnSetCaretsArray;
    property OnSetMarkersArray: TATStringsSetMarkers read FOnSetMarkersArray write FOnSetMarkersArray;
    property OnSetAttribsArray: TATStringsSetAttribs read FOnSetAttribsArray write FOnSetAttribsArray;

but code lacks events for the paired editor (which has the same Strings object).
so code needs additional events like

• OnGetCaretsArray2
• OnGetMarkersArray2
• etc

and editor must set these new events when editor-frame is splitted. not hard work. but not interesting. maybe later.
