How to make a single line bold in a RichEdit?

Question

How can I get one specific line to be bold in a RichEdit?

Answer 1

Formatting in a rich edit control is done like this:

1. Select the text to which formatting is to be applied.
2. Apply that formatting to the selection.

It goes something like this:

RichEdit1.SelStart := SelectionStart;
RichEdit1.SelLength := SelectionLength;
RichEdit1.SelAttributes.Style := RichEdit1.SelAttributes.Style + [fsBold];

Of course, you have to work out what to use in place of SelectionStart and SelectionLength. Ultimately that comes down to how you are managing the text and I don't think there's enough information in the question to give you a single definitive answer on that topic.
