Question

I need to change the font color property of the RichEditorViewer of the default pages, but I can't find the control names or property name, I need help with this...

The RichEditorViewer of the InfoBeforePage (I need to change the font color):

This is the code I'm using:

const
  Custom_Height = 570;
  Custom_ProgressBar_Height = 30;
  Page_Color = $7b2b68;
  Page_Color_Alternative1 = clblack;
  Page_Color_Alternative2 = clwhite;
  Font_Color = $fffbff;

var
  DefaultTop,
  DefaultLeft,
  DefaultHeight,
  DefaultBackTop,
  DefaultNextTop,
  DefaultCancelTop,
  DefaultBevelTop,
  DefaultOuterHeight: Integer;

procedure InitializeWizard();

  // Pages (Size)
  WizardForm.Height := Custom_Height;
  WizardForm.InnerPage.Height := WizardForm.InnerPage.Height + (Custom_Height - DefaultHeight);
  WizardForm.LicensePage.Height := WizardForm.LicensePage.Height + (Custom_Height - DefaultHeight);

Here is simple RTF document with many attributes changed:

And here is appropriate code for it:

{\rtf1\ansi\ansicpg1250\deff0\deflang1051{\fonttbl{\f0\fnil\fcharset0 Calibri;}{\f1\fnil\fcharset0 Times New Roman;}} {\colortbl ;\red0\green77\blue187;\red255\green0\blue0;} {*\generator Msftedit 5.41.21.2510;}\viewkind4\uc1\pard\sa200\sl276\slmult1\lang9\f0\fs22 Hello. This is \cf1 blue text\cf0 . \cf2 And this text is red\cf0 . This is \i italic \i0 & \b bold\b0 .\par \f1 Even changing font to Times is possible. \fs44 This text is 22 size.\f0\fs22\par \par \par }

Changing the color is possible with flag \cfX your text here \cf0 where X is your desired color number.

Colors are saved in colortbl in the head of document (as RGB values, black is missing):

{\colortbl;\red0\green77\blue187;\red255\green0\blue0;}

so black = cf0, blue = cf1, red = cf2 etc.

To assing new text simply assign your new text to RTFText variable:

WizardForm.InfoBeforeMemo.RTFText := '{\rtf1\ansi\ansicpg1250\deff0\deflang1051{\fonttbl{\f0\fnil\fcharset0 Calibri;}{\f1\fnil\fcharset0 Times New Roman;}}
{\colortbl ;\red0\green77\blue187;\red255\green0\blue0;}
{\*\generator Msftedit 5.41.21.2510;}\viewkind4\uc1\pard\sa200\sl276\slmult1\lang9\f0\fs22 Hello. This is \cf2 blue text\cf0 . \cf2 And this text is red\cf0 . This is \i italic \i0 & \b bold\b0 .\par
\f1 Even changing font to Times is possible. \fs44 This text is 22 size.\f0\fs22\par
\par
\par
}';

In the example above I changed color of blue text to red.

You are probably looking for InfoBeforeMemo: TRichEditViewer component which is located on page InfoBeforePage

This page (NewNotebookPage) is property of TWizardForm (TSetupForm).

Here we go:

TRichEditViewer = class(TMemo)
  property RTFText: AnsiString; write;
  property UseRichEdit: Boolean; read write;
end;

So you need to change property RTFText which is pure AnsiString.

That means it is pure text, there is no property 'Font' or similar. RTF text is simple text in special format which looks like this:

{\rtf1\ansi{\fonttbl\f0\fswiss Helvetica;}\f0\pard This is some {\b bold} text.\par }

So if you need to change the font you need to parse it manually - e.g. by changing fswiss Helvetica to your desired font and saving everything back.
