【转】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; }
