你说的那个TLOGFONT.lfWidth是所谓的平均宽度,请看help
lfWidth
Specifies the average width, in logical units, of characters in the font.
If lfWidth is zero, the aspect ratio of the device is matched against the
digitization aspect ratio of the available fonts to find the closest match,
determined by the absolute value of the difference.
看你的意思,恐怕是想要这个东西吧:TEXTMETRICS
可以用GetTextMetrics取得。其中包括tmAveCharWidth、tmMaxCharWidth
和tmWeight三个与宽度有关的值,该有你要的东西了吧!
