字体主要是用于修饰文字输出的形状、高度、宽度、粗度、倾斜、删除线等。
| BOOL CreateFontIndirect(const LOGFONT* lpLogFont); | 根据LOGFONT结构体创建一个字体 |
| BOOL CreateFont( int nHeight, int nWidth, int nEscapenment, intnOrientation, int nWeight, BYTE bItalic, BYTE bUnderline, BYTE cStrikeOut, BYTE nCharset, BYTE nOutPrecision, BYTE nClipPrecision, BYTE nQuality, BYTE nPitchAndFamily, LPCTSTR lpszFacename ); |
根据指定数值创建字体，其参数与LOGFONT成员一致，故等价于 CreateFontIndirect |
| BOOL CreatePointFont(int nPointSize, LPCTSTR lpszFaceName, CDC* pDC = NULL); | 根据字体的名字和高度创建字体 |
| BOOL CreatePointFontIndirect(const LOGFONT* lpLogFont, CDC* pDC = NULL); | 根据LOGFONT结构体创建点字体 |
| static CFont* FromHandle(HFONT hFont) | 将HFONT句柄转换为CFont对象 |
| operator HFONT() const | 从CFont对象中获取HFONT句柄 |
| int GetLogFont(LOGFONT* pLogFont); | 获取字体的名称和高、宽等属性信息 |

微软提供的例子：
// The code fragment shows how to create a font object, // select the font object into a DC (device context) for text // drawing, and finally delete the font object. // Initializes a CFont object with the specified characteristics. CFont font; VERIFY(font.CreateFont( 12, // nHeight 0, // nWidth 0, // nEscapement 0, // nOrientation FW_NORMAL, // nWeight FALSE, // bItalic FALSE, // bUnderline 0, // cStrikeOut ANSI_CHARSET, // nCharSet OUT_DEFAULT_PRECIS, // nOutPrecision CLIP_DEFAULT_PRECIS, // nClipPrecision DEFAULT_QUALITY, // nQuality DEFAULT_PITCH | FF_SWISS, // nPitchAndFamily _T("Arial"))); // lpszFacename // Do something with the font just created... CClientDC dc(this); CFont* def_font = dc.SelectObject(&font); dc.TextOut(5, 5, _T("Hello"), 5); dc.SelectObject(def_font); // Done with the font. Delete the font object. font.DeleteObject();
