Not that I know.

The caret is drawn by the OS. At least on windows. Apparently GTK does not have it, and the code in the Lcl/widgetset emulates it (but has no property for color).
On Mac, I do not know what happens.

SynEdit can influence the shape of the caret. But the IDE has no setting to influence this, you would have to add your own change in the IDE code.

Thank you,
This problem in just 64 bit QT on osx on corbon is okey short way is change background color, or change color set. https://code.google.com/p/delphi-ide-theme-editor/ 2300 color themes for lazarus :)

It might be now, but you need to do a couple of code changes, since no options exist.

unit:
components\synedit\syneditpointclasses.pas

line 2410
constructor TSynEditScreenCaret.Create(AHandleOwner: TWinControl);
change (old)
   FCaretPainter := TSynEditScreenCaretPainterSystem.Create(AHandleOwner);
into (new)
   FCaretPainter := TSynEditScreenCaretPainterInternal.Create(AHandleOwner);
Then find  (same unit),
procedure TSynEditScreenCaretPainterInternal.Paint;

and change the color
- black inverts
- white does nothing
- red inverts the blue and green, but leaves red untouched. if you have some medium grey as background, try $808080

thank you Martin, I can look next week.

Hello Martin,
After this message, syneditpointclasses.pas file is changed, create codes etc. If its possible sent new suggestion please?

Still the same, just line numbers are changed. Search for TSynEditScreenCaret.Create(

Or go to ide/SourceSynEditor and
in  line 1610
   constructor TIDESynEditor.Create(AOwner: TComponent);
add
ScreenCaret.ChangePainter(TSynEditScreenCaretPainterInternal);
TSynEditScreenCaretPainterInternal(ScreenCaret.Painter).Color :=

Something wrong but what is wrong :)
I got svn version fpc & lazarus I added lines from source. I wrote create code is different in your message, I told about that.

/opt/lazarus/components/synedit/syneditpointclasses.pas .....
2644:{ TSynEditScreenCaret }

constructor TSynEditScreenCaret.Create(AHandleOwner: TWinControl);
begin
   Create(AHandleOwner, TSynEditScreenCaretPainterSystem);
end;
constructor TSynEditScreenCaret.Create(AHandleOwner: TWinControl;
   APainterClass: TSynEditScreenCaretPainterClass);
begin
   inherited Create;
   FCaretPainter := APainterClass.Create(AHandleOwner, Self);
   FLockCount := -1;
   ResetCaretTypeSizes;
   FHandleOwner := AHandleOwner;
   FVisible := False;
   FCurrentVisible := False;
   FCurrentCreated := False;
   FCurrentPosX := -1;
   FCurrentPosY := -1;
   FClipExtraPixel := 0;
   FLockCount := 0;
end;

Replace this with
     Create(AHandleOwner, TSynEditScreenCaretPainterInternal);

and then

procedure TSynEditScreenCaretPainterInternal.Init;
begin
   FSavePen := TPen.Create;
   FColor := clBlack;
   inherited Init;
end;

replace clBlack with your choice

I did before, when start IDE, IDE give Access violation, and terminate

I just tried this myself (under win32), no error. IDE started just fine. Make sure you have todays SVN. And this, and the color are the 2 only changes in the file.

Otherwise try the 2 lines in SourcSynEditor I sent 2 mails before.

If it still happens maybe it is a mac only bug, could you try and get a stacktrace?

I tryed all, but same result, "Access violation." and IDE terminate. source editor is opening, but default colors, popup error message and click ok or cancel IDE terminate.
I'm still not use to osx, how can I get stacktrace?

You will need gdb. (codesigned)
See the wiki. Unfortunately, I can not advice myself on how to codesign gdb.

You can debug the IDE inside the IDE, by opening ide/lazarus.lpi

Or you may run in a shell (there is a lazarus somewhere inside the lazarus.app folder, find it , and use that path below) gdb /path/to/laz/lazarus.app/......./lazarus
then in gdb, enter "r" and return and when the error happen (lazarus will freeze, gdb will print something), enter "bt" and return.

I am doing further changes to the code, so maybe just use the old version, until I commit again.

lazarus r47718:
on qt x64:

   {$IFDEF LCLCarbon}
     FForcePaintEvents := True;
   {$ELSE}
     FForcePaintEvents := True; --> this is work normal now, carret is

showing and blinking, in carbon work too

   {$ENDIF}

I attached 2 screenshots. How to view carret in widgetset. qt little bit thin and down I think.
this is in carbon :
this is in QT :

I think now can try change colour for visibility in dark(black) background.

FColor := $CCD148;// Medium Turquoise
//todo- for me maybe change shape caret too

will you add this caret color property to lazarus IDE options -> Editor -> Display -> Colors ?
Thank you.
