改变Cstatic控件的颜色

[yuan697]

我这样创建一个CStatic控件

DlgStatic* newstatic;
newstatic = new DlgStatic();
newstatic->Create("Name",WS_CHILD|WS_VISIBLE|SS_NOTIFY|SS_SUNKEN,CRect(2,2,50,50),this,IDC_STATIC);
newstatic->ShowWindow(SW_SHOW); 

其中DlgStatic是一个从CStatic派生来的类，类中有变量
COLORREF m_clrFore; // foreground color
COLORREF m_clrBack; //background color
CBrush m_brush;
构造函数中对变量初始化，onCtrlColor更改颜色

DlgStatic::DlgStatic()
{
	m_clrFore = RGB(255,255,0);  
    m_clrBack = RGB(192,192,192);
    m_brush.CreateSolidBrush(m_clrBack);
}
HBRUSH DlgStatic::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) 
{
	HBRUSH hbr = CStatic::OnCtlColor(pDC, pWnd, nCtlColor);
	
	// TODO: Change any attributes of the DC here
	if(pWnd->GetDlgCtrlID() == IDC_STATIC)
	{
             pDC->SetTextColor(m_clrFore);
		pDC->SetBkColor(m_clrBack);
		return (HBRUSH)m_brush.GetSafeHandle();  
	}
	// TODO: Return a different brush if the default is not desired
	return hbr;
}

但是运行的时候控件的颜色还是默认的颜色，不知道这是什么错误

HBRUSH DlgStatic::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CStatic::OnCtlColor(pDC, pWnd, nCtlColor);

// TODO: Change any attributes of the DC here
if(pWnd->GetDlgCtrlID() == IDC_STATIC)
{
pDC->SetTextColor(m_clrFore);
pDC->SetBkColor(m_clrBack);
return (HBRUSH)m_brush.GetSafeHandle();
}
// TODO: Return a different brush if the default is not desired
return hbr;
}

红色那个ID是默认ID,一般static都是用这个ID,也就是说你不能用这个ID作为唯一的ID来区分你的这个控件。

自己自定义一个ID来代替ID_STATIC吧。

处理控件的反射消息 =WM_CTLCOLOR，而不是 WM_CTLCOLOR 。

BEGIN_MESSAGE_MAP(ClxStatic, CStatic)
　　 ON_WM_CTLCOLOR_REFLECT()
　　END_MESSAGE_MAP()
　　HBRUSH ClxStatic::CtlColor(CDC* pDC, UINT /*nCtlColor*/)
　　{
　　 // TODO: Change any attributes of the DC here
　　 m_brushBack.Detach();
　　 m_brushBack.CreateSolidBrush(m_clrBack);
　　 pDC->SetBkColor(m_clrBack);
　　 pDC->SetTextColor(m_clrText);
　　 // TODO: Return a non-NULL brush if the parent's handler should not be called
　　 //return NULL;
　　 return (HBRUSH)m_brushBack.GetSafeHandle();
　　}
