win32之取画刷的方法

取画刷（HBRUSH) 的六种方法2009-07-23 15:00HBRUSH 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;
}

第一种方法和第二种方法自己测试了可以使用，后面的还没有测试。
