1) If you want only two types of text (normal and bold), do the following:

- in Delphi, double click RVStyle component. You'll see a collection of text

styles

- delete all styles except for two; set font of these styles - normal for

the first style (index=0), bold for the second style (index=2)

- add "Bold" button (TSpeedButton) for switching normal and bold text:

procedure TForm1.SpeedButton1Click(Sender: TObject);

begin

if SpeedButton1.Down then

RichViewEdit1.ApplyTextStyle(1)

else

RichViewEdit1.ApplyTextStyle(0);

end;

- process TRichViewEdit.OnCurTextStyleChanged

procedure TForm1.ichViewEdit1CurTextStyleChanged(Sender: TObject);

begin

SpeedButton1.Down := RichViewEdit1.CurTextStyleNo<>0;

end;

This code is from the demo Demos\Delphi\DB Demos\1 DBRichViewEdit\

(and I do not think that the code above is overcomplicated :)

2) You can use RichViewActions http://www.trichview.com/resources/actions/

You can just add TrvActionFontBold action, assign it to some button/menu

item, and all will work without writing any code.

If you never worked with actions before, I can explain more detaily.

But RichViewActions is quite a large project, it includes many built-in

forms, so it may noticeably increase exe file size (it is ok is you want to

build more or less complete word processor, but may be it's an overkill for

only one "Bold" button)

3) If you do not want using RichViewActions, but want to implement several

commands like "Bold", "Italic", "Change font", "Change font color", etc.,

look at the demo Demos\Delphi\Editors\Editor 2\

It is not very complicated, but it may takes a time to study it.
