 |
|
Is there an elegant way of changing the color of sections of the Text in
RichEdit *without* selecting the text and then changing SelAttributes? Since
I want to be able to highlight various parts of a paragraph, I find the
flickering caused by the Caret and the inverted selections rather ugly.
I found a rather crude approach by doing a:
Text :=
'{rtf1ansiansicpg1252deff0deflang1031{fonttbl{f0fswissfcharset0
Arial;}}{colortbl ;red255green0blue0;}Hallo cf1 Americacf0 !';
but apparently this also includes Fonts and Charactersets, which I would
rather not touch...
Again thanks for any suggestions!
Ralf

Not easily. |

Have you tried doing the modifications inside a BeginUpdate/EndUpdate? |

If you really want to do this, you could stream the rtf out, parse the |
contents of the stream looking for the colour definition you want and change
the rgb values before streaming it back in.. as I say, not easily <g>.
