I find that using TcursorTool to plot a line on a chart does not seem to function in Delphi2005. Or at least my program that used to work doesnt seem to work under Delphi 5. It compiles OK but does not plot the cursor line on the chart screen.

Hi Mike,

Could you please post the code you are using for creating the TCursorTool or post small project we can run "as-is" so we can reproduce the problem here? The project should be posted at the steema.public.attachments newsgroup.

Thanks in advance.

Hi Narcis
This is a routine taken from my program (which used to work well under Delph6). The routine is to toggle a vertical yellow cursor onto a Chart, the position being set up elsewhere in the program.

var MyCursor: TCursorTool;

procedure TForm1.MarkLineClick(Sender: TObject);
begin
If MarkNewLIne= -1 then
begin

MyCursor.free;
MarkNewLine:= 1;
exit;
end;
MyCursor:=TCursorTool.Create(Self);
MyCursor.Style:= cssVertical ;
MyCursor.Pen.Style:= psSolid;
MyCursor.Pen.Mode:= pmNotXor;
MyCursor.Pen.Color:= clYellow;
MyCursor.Pen.Width:= 6;
MyCursor.RedrawCursor;
MyCursor.Visible:= true;
MyCursor.FollowMouse:= false;
MyCursor.ParentChart:=Chart;
MarkNewLine:= -MarkNewLine;
end;


The actual drawing of the cursor line is by
MyCursor.XValue:= StrTime;
in another procedure.

Hi Mike,

The problem is the TCursorTool.Pen.Width property in Delphi 2005. If its value is bigger than 1 then the Cursor Tool is not displayed. I have included this error in our bug list to be fixed for the next releases. Meanwhile the only workaround is setting the width to 1.

Thanks Narcis.

Hi Mike,

This has been fixed for the upcoming v7.04 version. Just stay tunned to the forums or have a look a the customer download area because it will be released soon.
