    17.4 字体枚举

    17.4.1 枚举函数

    (1)EnumFontFamiliesEx函数

    参数

    含义

    HDC hdc

    handle to DC

    LPLOGFONT lpLogfont

    传入LOGFONT结构的指针

    注意:如果lfCharset=DEFAULT_CHARSET;

    (2)EnumFontFamExProc回调函数(在每找到一种字体,该函数就被调用一次)

     

    参数

    含义

    ENUMLOGFONTEX *lpelfe

    指向含有字体的逻辑属性的ENUMLOGFONTEX结构的指针

    NEWTEXTMETRICEX *lpntme

    指向含有字体物理属性的结构的指针

    DWORD FontType

    指定字体类型,此参数可为下列值的组合。

    DEVICE_FONTTYPE, RASTER_FONTTYPE, TRUETYPE_FONTTYPE

    LPARAM lParam

    由EnumFontFamiliesEx中lParam指定的数据

    【EnumFont程序】枚举计算机上的所有字体

    17.4.2 ChooseFont对话框

    (1)CHOOSEFONT结构

    字段

    含义

    lStructSize

    结构体长度

    hwndOwner

    所属窗口

    hdc

    当Flags字段中指定CF_PRINTERFONTS时,它是打印机的DC句柄。

    lpLogFont

    指向一个LOGFONT结构体的指针

    iPointSize

    选择的字体大小,单位是1/0磅

    Flags

    CF_INITTOLOGFONTSTRUCT:根据ChooseFont函数中的LOGFONT初始化。

    CF_TTONLY:只使用TrueType字体

    CF_FIXEDPITCHONLY:只显示等宽字体

    CF_SCRIPTSONLY:非符号字体

    CF_SCREENFONTS:屏幕字体

    CF_PRINTERFONTS:打印机字体

    CF_BOTH:屏幕字体和打印机字体

    CF_EFFECTS:对话框中显示“效果”复选框,包含下划线和删除复选框,还允许选择文本颜色。

    CF_LIMITSIZE:显示字体的尺寸限于nSizeMin和nSizeMax之间。

    CF_NOSTYLESEL:不显示“字形”组合列表框

    CF_NOSIZESEL:不显示“大小”组合列表框

    rgbColors

    选择的字体颜色,如果Flags字段的CF_EFFECTS被设置,对话框将根据这个数值初始化“颜色”下拉列表框 。另外,函数返回时在这里返回用户选择的字体颜色。

    hInstance

    lpszStyle

    nFontType

    返回用户选择的字体是属于哪一类的,可能返回值有:BOLD_FONTTYPE、ITALIC_FONTTYPE、PRINTER_FONTTYPE、REGULAR_FONTTYPE、SCREEN_FONTTYPE等。

    nSizeMin

    设置用户可选择的字体最小的磅值(需指定CF_LIMITSIZE)

    nSizeMax

    设置用户可选择的字体最大的磅值(需指定CF_LIMITSIZE)

    (2)ChooseFont函数

      ①该函数会根据像素点的大小,使用逻辑英寸为单位来计算lfHeight字段。也就是根据LOGPIXELSY来磅值转化为lfHeight。如当LOGPIXELSY=96时,需要字体的高度为1英寸,则应在“字体”对话框中选择72磅的Times Roman字体。这里ChooseFont函数返回时,LOGFONT结构的lfHeight=-96(注意,有一个负号)

      ②LONGFONT中的lfHeight使用的是逻辑坐标,所以更改映射模式时,这里的值需相应的变化。

      ③ChooseFont函数设置的LOGFONT的lfHeight字段总是使用像素为单位的,且它仅适合视频显示(参考①的说明)

      ④CHOOSEFONT字段的iPointSize表示字体的磅值的大小,以1/10磅的为单位,无论映射模式怎么改变,这个值都不会变。可以将该字段转化为逻辑尺寸供fHeight使用。
