取画刷(HBrush)的6种方法



HBRUSH hbr;

第一种: hbr= CreateSolidBrush(RGB(255,0,0));    //单色的画刷

第二种: hbr= (HBRUSH)GetStockObject(BLACK_BRUSH);  //只能取特定颜色的画刷,如BLACK_BRUSH,GRAY_BRUSH等刷

第三种: hbr= CreatePatternBrush(HBITMAP hbmp);    //得到位图画刷

第四种: hbr = CreateHatchBrush(int fnStyle, COLORREF clrref)    //创建一种带阴影的画刷

第五种: hbr= CreateBrushIndirect(LOGBRUSH);     //通过LOGBRUSH结构体来取画刷

   

typedef struct tagLOGBRUSH {

    UINT         lbStyle; //画刷类型

    COLORREF lbColor; //颜色
        LONG         lbHatch; //阴影
} LOGBRUSH, *PLOGBRUSH;

第六种: hbr= HBRUSH CreateDIBPatternBrush(       //通过与设备无关位图创建一个画刷
        HGLOBAL hglbDIBPacked,      // handle to DIB

     UINT fuColorSpec        // color table data
      );

例如：

HBRUSH CAfdView::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)

{

HBRUSH hbr = CFormView::OnCtlColor(pDC, pWnd, nCtlColor);

// TODO: Change any attributes of the DC here

if (pWnd->GetDlgCtrlID()==IDC_STATIC1)

{

    pDC->SetTextColor(RGB(200,0,0));

    pDC->SetBkColor(RGB(0,0,255));

  static HBRUSH hBrush = CreateSolidBrush(RGB(222,0,255));

  return hBrush;

}

        // TODO: Return a different brush if the default is not desired

else

  return hbr;

}

改变对话框背景色

HBRUSH CDqfDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)

{

HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

// TODO: Change any attributes of the DC here

// TODO: Return a different brush if the default is not desired

if(nCtlColor == CTLCOLOR_DLG)

   {

   CBrush *brush;

    brush = new CBrush(RGB(221,221,221));

   return (HBRUSH)(brush->m_hObject);

   }

return hbr;

}
