[SOLVED] Unwanted additional line in the end of TRichMemo.
« on: December 13, 2024, 04:12:25 pm »
I have added a RichMemo to a form. I have entered two lines in RichMemo1.Lines.
But when I run the app there is an empty third line.
Can I get rid of it?
I tried to set RichMemo1.ReadOnly := True, but it does not help, the line is still there.
A sample project is attached.

Hi
Maybe:
Code: Pascal  [Select][+][-]
  1. { we don't want that pestering last empty line }
  2. RichMemo1.Lines.SkipLastLineBreak:= true;
this could work?!?

The other responses are best, but there is always *Untested*
Code: Pascal  [Select][+][-]
  1. Memo1.text:=Leftstring(Memo1.text,Length(memo1.text)-1)  {or -2 if your line is #13#10}
  2.

None of these works:

Code: Pascal  [Select][+][-]
  1.  RichMemo1.Lines.SkipLastLineBreak := True;
  2.  RichMemo1.Lines.TrailingLineBreak := False;
  3.  RichMemo1.Lines.Options := RichMemo1.Lines.Options - [soTrailingLineBreak];

I uploaded the snippet with them and attached it.

...
Code: Pascal  [Select][+][-]
  1. Memo1.text:=Leftstring(Memo1.text,Length(memo1.text)-1)  {or -2 if your line is #13#10}

...

The last #13#10 is not in the text, but it is displayed, this is the problem. Memo1.text:='1'#13#10'2'; still shows an empty third line.

EDIT: I tried again on another PC (still not sure what is different). Memo1.text:='1'#13#10'2'; does not show an empty line in the end.
Also I found this https://forum.lazarus.freepascal.org/index.php/topic,28818.15.html, because the issue also occurs in TMemo.
Maybe I will use TKMemo, it does not have this issue.

The issue is solved, more info here:
https://forum.lazarus.freepascal.org/index.php/topic,69804.msg543027.html
Shortly, TRichMemo.Lines.Add shall not be used in this case.
InsertFontText can be used instead (see https://wiki.freepascal.org/RichMemo/FAQ#Add_text_with_font, I have fixed the example).
