Inno Setup，如何更改 RichEditorView 的颜色

Question

我需要更改默认页面的RichEditorViewer 的字体颜色属性，但找不到控件名称或属性名称，我需要帮助...

InfoBeforePage的RichEditorViewer（我需要更改字体颜色）：

这是我正在使用的代码：

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();
begin

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

Answer 1

您可能正在寻找 InfoBeforeMemo：位于页面 InfoBeforePage

上的 TRichEditViewer 组件

此页面 (NewNotebookPage) 是 TWizardForm (TSetupForm) 的财产。

我们开始吧：

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

所以你需要改变属性 RTFText 是纯 AnsiString。

这意味着它是纯文本，没有“字体”或类似属性。 RTF 文本是特殊格式的简单文本，如下所示：

{\rtf1\ansi{\fonttbl\f0\fswiss Helvetica;}\f0\pard 这是一些 {\b 粗体} 文本。\par }

因此，如果您需要更改字体，则需要手动解析 - 例如通过将 fswiss Helvetica 更改为您想要的字体并保存所有内容。

更多关于 RTF 的信息在这里：http://en.wikipedia.org/wiki/Rich_Text_Format

Answer 2

这是一个简单的 RTF 文档，更改了许多属性：

这里有合适的代码：

{\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 你好。这是 \cf1 蓝色文本\cf0 。 \cf2 这个文本是 red\cf0 。 这是 \i italic \i0 & \b bold\b0 .\par \f1 甚至将字体更改为 时间是可能的。 \fs44 此文本大小为 22。\f0\fs22\par \par \par }

更改颜色可以通过标记 \cfX 您在此处的文本 \cf0 其中 X 是您想要的颜色编号。

颜色保存在文档头部的 colortbl 中（作为 RGB 值，缺少黑色）：

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

所以黑色 = cf0，蓝色 = cf1，红色 = cf2 等等。

要分配新文本，只需将新文本分配给 RTFText 变量：

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
}';

在上面的示例中，我将蓝色文本的颜色更改为红色。
