TRichEdit 中同一行中的彩色文本

Question

How to write text in the same line but with different color? (I use richedit).

procedure TForm1.btnEClick(sender: TObject);
begin

  m0.SelAttributes.Color := clBlue;
  m0.SelAttributes.Style := [fsBold];
  m0.lines.add('This is blue and it is bold');
  m0.SelAttributes.Color := clGreen;
  m0.SelAttributes.Style := [fsBold];
  m0.lines.add ('This is Green and it is bold');
  m0.lines.add('');
  m0.lines.add('But how to write text in the same line with different color?');
  // i want to have both blue and green in the same line 
end;

Answer 1

You're on the right track. Just change SelAttributes and use SelText instead of Lines.Add :

procedure TForm4.FormCreate(Sender: TObject);
begin
  RichEdit1.Clear;
  RichEdit1.SelAttributes.Color := clBlue;
  RichEdit1.SelAttributes.Style := [fsBold];
  RichEdit1.SelText := 'This is bold blue text.';
  RichEdit1.SelAttributes.Color := clRed;
  RichEdit1.SelAttributes.Style := [fsItalic];
  RichEdit1.SelText := #32'This is italic red text';
end;

This produces

if you are using themes... answer above won't work..
you cannot see any colors... till you remove seFont from styles..

RichEdit1.styleElements:=richedit1.styleElements-[seFont];

eg.

....
amsg:='Hola';

RichEdit1.SelStart := Length(RichEdit1.Lines.Text);
RichEdit1.SelAttributes.Color := acolor;
RichEdit1.Lines.Add(amsg + sLineBreak);
RichEdit1.SelLength := Length(amsg + sLineBreak);

For the last piece of text in the line, include a carriage return to finish off the line.

RichEdit1.SelAttributes.Color := clGreen;
RichEdit1.SelAttributes.Style := [];
RichEdit1.SelText := 'This is the last piece of text on the line.' + #13;
