本文介绍了两种设置文本格式的方法：一种适用于2nd，通过直接设置TCharFormat和TCharFormatMask来实现字体、颜色等属性的调整；另一种适用于2nd和3rd，先创建字体对象再设置格式。

先说第一种，它只适用于2nd

           TCharFormat charFormat;
    Mem::FillZ(&charFormat,sizeof(TCharFormat));
    TCharFormatMask   charMask;
    Mem::FillZ(&charMask,sizeof(TCharFormatMask));  
    TFontSpec sFontSpec = PocoUtils::NormalFont()->FontSpecInTwips();
    charFormat.iFontSpec.iTypeface =  sFontSpec.iTypeface;
    charMask.SetAttrib(EAttFontTypeface);
    charFormat.iFontSpec.iHeight = sFontSpec.iHeight;
    charMask.SetAttrib(EAttFontHeight);
    charFormat.iFontPresentation.iTextColor = KDarkGreenColour;
    charMask.SetAttrib(EAttColor);
    charFormat.iFontPresentation.iStrikethrough = (TFontStrikethrough)EFalse;
    charMask.SetAttrib(EAttFontStrikethrough);  
    charFormat.iFontPresentation.iUnderline = (TFontUnderline)EFalse;
    charMask.SetAttrib(EAttFontUnderline);
    CCharFormatLayer* FormatLayer1 = CCharFormatLayer::NewL(charFormat,charMask);
    iTitle->SetCharFormatLayer(FormatLayer1);

再来介绍第二种，它使用于2nd和3rd

CFont* font=NULL; 
#ifdef _UIQ3_SDK_ 
            TFontSpec fontSpec=CEikonEnv::Static()->NormalFont()->FontSpecInTwips();
            fontSpec.iHeight-=fontSpec.iHeight/4;
            fontSpec.iFontStyle.SetPosture(EPostureUpright);
            CEikonEnv::Static()->ScreenDevice()->GetNearestFontInTwips(font,fontSpec); 
#else 
            font=CEikonEnv::Static()->NormalFont(); 
#endif 
            CGlobalText* globalText = (CGlobalText*)edwin->Text();
            TCharFormat charFormat;
            Mem::FillZ(&charFormat, sizeof(TCharFormat));
            TCharFormatMask charMask;
            Mem::FillZ(&charMask, sizeof(TCharFormatMask));
            TFontSpec sFontSpec = font->FontSpecInTwips();
            charFormat.iFontSpec.iTypeface = sFontSpec.iTypeface;
            charMask.SetAttrib(EAttFontTypeface);
            charFormat.iFontSpec.iHeight = sFontSpec.iHeight;
            charMask.SetAttrib(EAttFontHeight);
            charFormat.iFontPresentation.iTextColor = KDarkGreenColour;
            charMask.SetAttrib(EAttColor);
            globalText->ApplyCharFormatL(charFormat,charMask,0,edwin->TextLength());
