[一只正在啃的蜗牛]

CFont mFnt;
LOGFONT mLogFont;
memset(&mLogFont,0,sizeof(LOGFONT));
strcpy_s(mLogFont.lfFaceName,"Arial");
mLogFont.lfHeight=130;
mLogFont.lfWeight=FW_SEMIBOLD;
mFnt.CreatePointFontIndirect(&mLogFont);
pDC->SelectObject(&mFnt);

mLogFont.lfFaceName什么意思
FW_SEMIBOLD什么意思
CreatePointFontIndirect怎么解释

[schlafenhamster]

CFont::CreatePointFontIndirect
BOOL CreatePointFontIndirect( const LOGFONT* lpLogFont, CDC* pDC = NULL );

Return Value

Nonzero if successful, otherwise 0.

Parameters

lpLogFont

Points to aLOGFONT structure that defines the characteristics of the logical font. The lfHeight member of the LOGFONT structure is measured in tenths of a point rather than logical units. (For instance, set lfHeight to 120 to request a 12-point font.)

pDC

Pointer to the CDC object to be used to convert the height in lfHeight to logical units. If NULL, a screen device context is used for the conversion.

Remarks

This function is the same as CreateFontIndirect except that the lfHeight member of the LOGFONT is interpreted in tenths of a point rather than device units. This function automatically converts the height in lfHeight to logical units using the CDC object pointed to by pDC before passing the LOGFONT structure on to Windows.

When you finish with the CFont object created by the CreatePointFontIndirect function, first select the font out of the device context, then delete the CFont object.

、、、、、
lfWeight
Specifies the weight of the font in the range 0 through 1000. For example, 400 is normal and 700 is bold. If this value is zero, a default weight is used.
The following values are defined for convenience: Value Weight
FW_DONTCARE 0
FW_THIN 100
FW_EXTRALIGHT 200
FW_ULTRALIGHT 200
FW_LIGHT 300
FW_NORMAL 400
FW_REGULAR 400
FW_MEDIUM 500
FW_SEMIBOLD 600
FW_DEMIBOLD 600
FW_BOLD 700
FW_EXTRABOLD 800
FW_ULTRABOLD 800
FW_HEAVY 900
FW_BLACK 900

。。。。。。
lfFaceName
A null-terminated string that specifies the typeface name of the font. The length of this string must not exceed 32 characters, including the null terminator. The EnumFontFamilies function can be used to enumerate the typeface names of all currently available fonts. If lfFaceName is an empty string, GDI uses the first font that matches the other specified attributes.

请参考MSDN文档~~~

mLogFont.lfFaceName 这里代表给mLogFont这个结构体的成员lfFaceName复制，表示字体的名字
FW_SEMIBOLD 这就是一个宏定义，值是600，代表字体的宽度，可理解为加粗的程度
CreatePointFontIndirect 表示用mLogFont这种字体结构体初始化CFont对象mFnt

[绿色盒子]

MSDN是个好东西
mLogFont.lfFaceName：字体名称 如“宋体”
FW_SEMIBOLD：字体权重600 字体的权重范围为0到1000.例如，400表示正常，700表示粗体。如果此值为零，则使用默认权重。
CreatePointFontIndirect：初始化CFont对象中给定的特征LOGFONT结构。与相同CreateFontIndirect不同之处在于字体高度以点而不是逻辑单元的十分之几。
