S60 3rd中设置字体类型与字体大小

//首先查找机器支持的字体个数．
TInt iNumTypefaces = iCoeEnv->ScreenDevice()->NumTypefaces();

//然后就可以查找所有的字体
for(TInt i = 0; i < iNumTypefaces; i++)
{
TTypefaceSupport myTypefaceSupport;
iCoeEnv->ScreenDevice()->TypefaceSupport(myTypefaceSupport,i);
TBuf<KMaxTypefaceNameLength> aTemp;
aTemp.Copy(myTypefaceSupport.iTypeface.iName.Des());
}//这样就可以得到所有的aTypefaceName.

//设置指定的字体
TFontSpec fontSpec;
fontSpec.iTypeface.iName= aTemp;
fontSpec.iHeight = 40;
(这个地方也可以使用相对于别的字体的高度如下：
　const CFont* font = CEikonEnv::Static()->SymbolFont();
　fontSpec.iHeight = font->FontSpecInTwips().iHeight + 10;
)
//生成新的字体
CEikonEnv::Static()->ScreenDevice()->GetNearestFontInTwips(newFont, fontSpec);
//最后使用字体
CWindowGc::UseFont(newFont);





字体大小样式，全套的（注释掉的代码也是有效的）
const CFont* font = iEikonEnv->SymbolFont();
iOffScreenBitmapGc->UseFont( font );
iOffScreenBitmapGc->DrawText(_L("hello world"),TPoint(0,20) );
iOffScreenBitmapGc->DiscardFont();

CFont* fontNew = NULL;
TFontSpec fontSpec;
fontSpec.iTypeface.iName=font->FontSpecInTwips().iTypeface.iName;// KFontName;
//if (text->Bold())
//{
// // Set Bold
// fontSpec.iFontStyle.SetStrokeWeight(EStrokeWeightBold);
//}
//if (text->Italic())
//{
// // Set Italic
// fontSpec.iFontStyle.SetPosture(EPostureItalic);
//}
//fontSpec.iFontStyle.SetBitmapType(EAntiAliasedGlyphBitmap);
//fontSpec.iHeight=text->Height();
//// Set Underline
//if (text->Underline())
//{
// iGc->SetUnderlineStyle(EUnderlineOn);
//}

fontSpec.iHeight = font->FontSpecInTwips().iHeight + 40;

iOffScreenBitmapDevice->GetNearestFontInTwips(fontNew,fontSpec);
if (fontNew != NULL)
{
iOffScreenBitmapGc->UseFont( fontNew );
iOffScreenBitmapGc->DrawText(_L("hello world"),TPoint(0,100) );
iOffScreenBitmapGc->DiscardFont();

iOffScreenBitmapDevice->ReleaseFont(fontNew);
}
