I placed a TRichEdit control into a form.  As the TRichEdit box will be set to read-only, I don't want a cursor keep flashing on the edit box.
Is it possible to remove this cursor?  How can I do that?

Thanks.

Place it on a panel and set TPanel.Enabled := False;

@j42: That doesn't remove the cursor though.

Add the follwing line to your FormCreate for example:

YourRichEdit.Cursor := crNone;

crNone is not available in the object inspector so you have to set it programmatically.

Voilá! The cursor is hidden when moved over the rich edit.

Wyverex:

Not the mouse cursor, I mean the "cursor" which keeps flashing when you are typing text in the edit box.

I would use a timer and use the following code:

HideCaret(MyRichEdit.Handle);

Add a timer to your form (System page > Timer), select the timer and in the object inspector decrease the interval value (Interval = 10 works fine), now double-clic the timer and the procedure should be as follows:

procedure TForm1.Timer1Timer(Sender: TObject);
begin
  HideCaret(RichEdit1.Handle);
end;

Thanks lopardo2003 and sorry for the late reply.
I think it is quite resource consuming by using a timer here.

Thanks j42. Your solution is good if the TRichedit is only used for displaying something, because the user cannot work with the TRichedit anymore.

Yep, I understand. Copy and paste is disabled. Darn!
