摘要：
//语句：CreateBrushIndirect（constp1:TLogBrush｛Brush Structure｝）：HBRUSH；｛Return brush handle｝//TLogBrush是对tagLOGBRUSH结构的重新定义：tagLOGBRUSH=packedrecordbStyle:UINT；｛画笔样式｝lbColor:COLORREF；｛Color｝lbHatch:Longent；｛Shadow Style｝end//LbStyle可选值：BS
//声明:
CreateBrushIndirect(
const p1: TLogBrush {画刷结构}
): HBRUSH; {返回画刷句柄}
//TLogBrush 是 tagLOGBRUSH 结构的重定义:
tagLOGBRUSH = packed record
lbStyle: UINT; {画刷风格}
lbColor: COLORREF; {颜色}
lbHatch: Longint; {阴影样式}
end;
//lbStyle 可选值:
BS_SOLID = 0;
BS_NULL = 1;
BS_HOLLOW = BS_NULL;
BS_HATCHED = 2;
BS_PATTERN = 3;
BS_INDEXED = 4;
BS_DIBPATTERN = 5;
BS_DIBPATTERNPT = 6;
BS_PATTERN8X8 = 7;
BS_DIBPATTERN8X8 = 8;
BS_MONOPATTERN = 9;
//lbHatch 可选值:
HS_HORIZONTAL = 0;
HS_VERTICAL = 1;
HS_FDIAGONAL = 2;
HS_BDIAGONAL = 3;
HS_CROSS = 4;
HS_DIAGCROSS = 5;
//举例:
procedure TForm1.FormPaint(Sender: TObject);
var
b: TLogBrush;
BrushHandle: HBRUSH;
begin
b.lbStyle := BS_HATCHED;
b.lbColor := clRed;
b.lbHatch := HS_CROSS;
BrushHandle := CreateBrushIndirect(b);
Canvas.Brush.Handle := BrushHandle;
FillRect(Canvas.Handle, ClientRect, BrushHandle);
DeleteObject(BrushHandle);
end;
