DrawText wordBreak的问题
各位大侠，想问个问题，DrawText中如果设置了Dt_WordBreak标志后，显示的时候会按英文单词进行换行显示，现在的问题是我能不能得到换行后每行的字符个数，或者是有没有一个这样的系统API，给它一个区域和字体大小，它能按WordBreak那样返回能容下的字符数。
试过DrawTextEx(Handle, PChar(AText), -1, cRect, defGetTextLengrthFlag, @dtParams);通过dtParams.uiLengthDrawn来取得字符数，但是只对英文有效，中文不行。
各位，有没有方法可以解决一下~谢谢

用这个方法试下：http://stackoverflow.com/questions/7007280/delphi-draw-text-multiline-in-the-centre-of-a-rect

function DrawTextCentered(Canvas: TCanvas; const R: TRect; S: String): Integer;
var
DrawRect: TRect;
DrawFlags: Cardinal;
DrawParams: TDrawTextParams;
begin
DrawRect := R;
DrawFlags := DT_END_ELLIPSIS or DT_NOPREFIX or DT_WORDBREAK or
DT_EDITCONTROL or DT_CENTER;
DrawText(Canvas.Handle, PChar(S), -1, DrawRect, DrawFlags or DT_CALCRECT);
DrawRect.Right := R.Right;
if DrawRect.Bottom < R.Bottom then
OffsetRect(DrawRect, 0, (R.Bottom - DrawRect.Bottom) div 2)
else
DrawRect.Bottom := R.Bottom;
ZeroMemory(@DrawParams, SizeOf(DrawParams));
DrawParams.cbSize := SizeOf(DrawParams);
DrawTextEx(Canvas.Handle, PChar(S), -1, DrawRect, DrawFlags, @DrawParams);
Result := DrawParams.uiLengthDrawn;
end;
