CHARFORMAT structure of MFC是Microsoft Foundation Classes (MFC)即 微软类库中 字符格式类的结构。结构中不可或缺的两个成员是dwMask和 dwEffects，前者是定义或设置字符的字体、颜色、粗体、斜体、下划线等属性值，后者则是相关属性的效果。

CHARFORMAT Structure
The CHARFORMAT structure contains information about character formatting in a rich edit control.
Rich Edit 2.0: The CHARFORMAT2 structure is a Microsoft Rich Edit 2.0 extension of the CHARFORMAT structure. Rich Edit 2.0 and later allows you to use either structure with the EM_GETCHARFORMAT and EM_SETCHARFORMAT messages.
Syntax
typedef struct _charformat {
UINT cbSize;
DWORD dwMask;
DWORD dwEffects;
LONG yHeight;
LONG yOffset;
COLORREF crTextColor;
BYTE bCharSet;
BYTE bPitchAndFamily;
TCHAR szFaceName[LF_FACESIZE];
} CHARFORMAT;
Members
cbSize
Size in bytes of the specified structure. This member must be set before passing the structure to the rich edit control.

编辑本段dwMask

Members containing valid information or attributes to set. This member can be zero, one, or more than one of the following values.
CFM_BOLD
The CFE_BOLD value of the dwEffects member is valid.
CFM_CHARSET
The bCharSet member is valid.
CFM_COLOR
The crTextColor member and the CFE_AUTOCOLOR value of the dwEffects member are valid.
CFM_FACE
The szFaceName member is valid.
CFM_ITALIC
The CFE_ITALIC value of the dwEffects member is valid.
CFM_OFFSET
The yOffset member is valid.
CFM_PROTECTED
The CFE_PROTECTED value of the dwEffects member is valid.
CFM_SIZE
The yHeight member is valid.
CFM_STRIKEOUT
The CFE_STRIKEOUT value of the dwEffects member is valid.
CFM_UNDERLINE.
The CFE_UNDERLINE value of the dwEffects member is valid.

编辑本段dwEffects

Character effects. This member can be a combination of the following values.
CFE_AUTOCOLOR
The text color is the return value of GetSysColor(COLOR_WINDOWTEXT).
CFE_BOLD
Characters are bold.
CFE_DISABLED
RichEdit 2.0 and later: Characters are displayed with a shadow that is offset by 3/4 point or one pixel, whichever is larger.
CFE_ITALIC
Characters are italic.
CFE_STRIKEOUT
Characters are struck.
CFE_UNDERLINE
Characters are underlined.
CFE_PROTECTED
Characters are protected; an attempt to modify them will cause an EN_PROTECTED notification message.
yHeight
Character height, in twips (1/1440 of an inch or 1/20 of a printer's point).
yOffset
Character offset, in twips, from the baseline. If the value of this member is positive, the character is a superscript; if it is negative, the character is a subscript.
crTextColor
Text color. This member is ignored if the CFE_AUTOCOLOR character effect is specified. To generate a COLORREF, use the RGB macro.
bCharSet
Character set value. The bCharSet member can be one of the values specified for the lfCharSet member of the LOGFONT structure. Rich Edit 3.0 may override this value if it is invalid for the target characters.
bPitchAndFamily
Font family and pitch. This member is the same as the lfPitchAndFamily member of the LOGFONT structure.
szFaceName
Null-terminated character array specifying the font name.

编辑本段Remarks

To turn off a formatting attribute, set the appropriate value in dwMask but do not set the corresponding value in dwEffects. For example, to turn off italics, set CFM_ITALIC but do not set CFE_ITALIC.
相信大家没心情看完，现在我只解释一下dwmask与dweffects的区别：dweffects记录了字体的部分信息，如粗体，但是这些信息是否有效却是由swmask决定的，请看下面的解释，如：CFM_BOLD The CFE_BOLD value of the dwEffects member is valid.也就是说只有当dwmask&cfm_bold!=0时才表明字体 加粗，这也是为什么在最后help里面会强调关闭字体作用时，设置dwmask的值，而不是dweffects。（个人愚见，错误之处见谅）

QTextCharFormat介绍： QTextCharFormat类提供了QTextDocument中字符的格式化信息。 文档中文本的字符格式指定文本的可视属性，以及关于其在超文本文档中的角色的信息。 可以通过向setFont()函数提供字体来设置所使用的字体，并且可以调整其外观的各个方面以获得所需的效果。setFontFamily()和setFontPointSize()定义字体的族(例如时间)和打印大小;setFontWeight()和setFontItalic()提供对字体样式的控制。setFont

通过 pFont 中lfHeight 转换成 CHARFORMAT2 中的字体高度 yHeight

要考虑DPI映射比例。 LOGFONT::lfHeight单位是像素; CHARFORMAT2::yHeight单位是1/1440英寸或1/567厘米（现实长度），必须根据DC的映射模式换算到实际DC中的像素值。 lfHeight = yHeight * (GetDeviceCaps(hDC, LOGPIXELSY)/1440);

在调用CFontDialog打开的字体设置对话框中，或者在WORD等Office软件中，设置的字号，其实不是文字的高度（文字在竖直方向上的高度，即占用的像素值），文字的高度比字号数字略大。 1、与LOGFONT结构体中的lfHeight之间的关系 LOGFONT结构体中的lfHeight的高度实际上就是文字的实际高度，那么我们在使用 LOGFONT结构体创建字体

它有两个参数，一个参数是va_list类型的，用来存放第一个可选参数的地址。其实在程序的栈中，函数的所有参数都是在内存中连续分布的，所以可以通过强制参数的地址来获取可选参数的地址，然后保存在第一个参数中。该函数有两个参数，第一个参数是当前可变参数的地址，第二个参数是当前可变参数的类型。这个函数调用过后，第一个参数的值会变化，它会指向参数列表中下一个参数。固定参数和可选参数共同构成可变参数函数的参数列表。个可变参数的宏，它使得可以在宏定义中使用可变参数列表，可变参数的个数最少为1，否则编译会出错。......
