画笔与画刷

声明全局变量

HPEN hPen[7];
HBRUSH hBru[7];
int sPen[7]={PS_SOLID,PS_DASH,PS_DOT,PS_DASHDOT,PS_DASHDOTDOT,
PS_NULL,PS_INSIDEFRAME};
int sBru[7]={HS_VERTICAL,HS_HORIZONTAL,HS_CROSS,HS_DIAGCROSS,
HS_FDIAGONAL,HS_BDIAGONAL};

void MyPaint(HDC hdc);

创建画刷与画笔

   for (i=0;i<=6;i++)
   {
    hPen[i] = CreatePen(sPen[i],1,RGB(255,0,0));
    if(i==6)
     hBru[i]=CreateSolidBrush(RGB(0,255,0));
    else
     hBru[i]=CreateHatchBrush(sBru[i],RGB(0,255,0));
   }
   hdc=GetDC(hWnd);
   MyPaint(hdc);
   ReleaseDC(hWnd,hdc);

关联画刷与画笔并画图

void MyPaint(HDC hdc)
{
    int i,x1,x2,y;
 for (i=0;i<=6;i++)
 {
  y=(i+1)*30;
  SelectObject(hdc,hPen[i]);
  MoveToEx(hdc,30,y,NULL);
  LineTo(hdc,100,y);
 }
 x1=120;
 x2=180;

    for (i=0;i<=6;i++)
    {
  SelectObject(hdc,hBru[i]);
  Rectangle(hdc,x1,30,x2,y);
  x1+=70;
  x2+=70;
    }
}

删除画刷与画笔

case WM_DESTROY:
  for (i=0;i<=6;i++)
  {
   DeleteObject(hPen[i]);
   DeleteObject(hBru[i]);
  }
  PostQuitMessage(0);
  break;
