创建椭圆,并用brush填充,结果没有效果

[chzhk007]

HRGN hEllipse=CreateEllipticRgn(sScnCoor.x-12,sScnCoor.y-8,sScnCoor.x+12,sScnCoor.y+8);
LOGBRUSH logEllipseBrush;
logEllipseBrush.lbColor=RGB(110,20,50);
logEllipseBrush.lbStyle=BS_HOLLOW;
HBRUSH hEllipsBrush=CreateBrushIndirect(&logEllipseBrush);
FillRgn(m_hDC,hEllipse,hEllipsBrush);


不知道哪里出了问题??

[一个傻冒]

SelectObject()
要把刷子选入设备才能用啊.
你只创建了.

[teli_eurydice]

SelectObject()

[coordinate]

HRGN hEllipse=CreateEllipticRgn(sScnCoor.x-12,sScnCoor.y-8,sScnCoor.x+12,sScnCoor.y+8);
LOGBRUSH logEllipseBrush;
logEllipseBrush.lbColor=RGB(110,20,50);
logEllipseBrush.lbStyle=BS_HOLLOW;
HBRUSH hEllipsBrush=CreateBrushIndirect(&logEllipseBrush);
if(CreateBrushIndirect!=NULL) SelectObject(m_hDC, hEllipsBrush);//这个
FillRgn(m_hDC,hEllipse,hEllipsBrush);

pDC->SelectObject(&hEllipsBrush);

楼上正解~

[DentistryDoctor]

FillRgn不需要SelectObject
只因你的画刷是空心的(BS_HOLLOW)

试一次BS_SOLID?

DentistryDoctor(MVP-My heart will fly,in the sky.)说的对,

HRGN hEllipse=CreateEllipticRgn(sScnCoor.x-12,sScnCoor.y-8,sScnCoor.x+12,sScnCoor.y+8);

LOGBRUSH logEllipseBrush;
logEllipseBrush.lbColor=RGB(110,20,50);
logEllipseBrush.lbStyle=BS_SOLID;
HBRUSH hEllipsBrush=CreateBrushIndirect(&logEllipseBrush);
FillRgn(dc,hEllipse,hEllipsBrush);

改成实Solid Brush, Hollow brush.是个空刷子.

哦,原来刷子是空心的!
我已经用PaitRgn代替FillRgn了.
