Styles in RichEdit

I have a problem with getting the contens of a RichEdit in a special format.

The problem is very simple:The text property of a richedit gives me the plain text. I need a "StyledText"-property that enables me to get and set the text with special codes for beginning and end of bolded, italiced and underlined text.

If "begin bold" is marked as "<B>" and "end bold" the same, I would have the following "StyledText":

"The word <B>fat<B> is marked bold"

I know it's possible to select some text and check selattributes to see if it's bold and then set the codes accordingly. But its too time consuming to check a lot of text that way.  Offcourse should nesting of codes be possible as in:

"<U>The word <B>fat<B> is marked bold<U>",

where the sentence is underlined.

By the way, I'm using Delphi 3.02...

hi mickeyE

the only other wea i know is to get the rtf text of the control
(perhaps with exporting it with lines.savetostream) and get the attributes from there

Trying to get the delphi native richedit component is flogging a bit of a dead horse in my opinion.  I went through months of work trying to sort out a miniature version of Word in a text object and the best solution in the end was to use a third party component - specifically WPtools by Julian Ziersch is the best on the market.  You can use field codes to tag text and set up all the styles you like using tags/invisible markers/field codes.
The native RichEdit component is lacking in so many departments i simply wouldnt recommend using it.

I'm sorry I didn't mention that I don't want to use any 3rd party components.

So presumably you want the rich text format so you can read/write the attributes more quickly?

Yes... This "StyledText" property I mention.

I thing that rene100 is right about using the SaveToStream-functionality and write a TConversion-descendant class, that handles the conversion from rtf to "StyledText".... The Delphi documentation is very weak regarding writing such a class. Anyway I'm not really interested in saving the text, just getting it.

I will check this out soon, I just haven't had the time to do it.

Hi BlackMan,

I can't find the code of the styledtext question. Can you send me the code to my account or post it in the expert section?  Thanks a lot in advance.
