送分啦：怎么改变Static Text 的背景颜色？

[tobato]

气死我了！搞了老半天搞不定

[mzm100]

自己从CStatic派生一个类,重载OnPain()

[wavecheng]

响应WM_CTLCOLOR;
if(nCtlColor==CTLCOLOR_STATIC)
pDC->SetBkColor(RGB(255,0,0));

[cdq]

同意wavecheng(CryingOwl)。。。
在classwizard中重载，WM_CTLCOLOR

[Flysnow]

晚了一步　，同上

[tobato]

那会不会全都变了？ 我要变特定Static Text的颜色阿！！

[chenzhou35]

OnCtlColor( CDC* pDC, CWnd* pWnd, UINT nCtlColor );
有窗口指针传进来的。
if(pWnd.m_hWnd == m_SpecialStatic.m_hWnd)
pDC->SetBkColor(RGB(255,0,0));

[stevenW]

HBRUSH CF2Dlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

// TODO: Change any attributes of the DC here
if(pWnd==(CWnd*)GetDlgItem(IDC_STATIC1))
pDC->SetBkColor(RGB(0,255,0));
// TODO: Return a different brush if the default is not desired
return hbr;
}

[tobato]

to stevenW(无情的雨) 你的代码不好使，
再高楼上的是全部变色。

[tobato]

综合大家的招：
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

CStatic* pStatic1;
CStatic* pStatic2;
pStatic1 = (CStatic*)GetDlgItem(IDC_STATICINFO1);
pStatic2 = (CStatic*)GetDlgItem(IDC_STATICINFO2);
// TODO: Change any attributes of the DC here
if(nCtlColor==CTLCOLOR_STATIC)
{
if(pWnd->m_hWnd == pStatic1->m_hWnd)
pDC->SetBkColor(RGB(255,255,255));
if(pWnd->m_hWnd == pStatic2->m_hWnd)
pDC->SetBkColor(RGB(255,255,255));
}
// TODO: Return a different brush if the default is not desired
return hbr;

但是还是不能完全变成白色， 还差一点点是灰色的，怪难看的！
还有没有办法？

[stevenW]

屁话，我的代码怎么不好使?

在classwizard中重载，WM_CTLCOLOR
if(nCtlColor==CTLCOLOR_STATIC)
pDC->SetBkColor(RGB(255,0,0));

3.用法(假如m_stInfo是CLabel)

m_stInfo
.SetFontName("宋体")
.SetFontSize(12)
.SetTextColor(RGB(0,255,0))
.SetFontUnderline(FALSE)
.SetBkColor(RGB(0,0,0))
.SetFontItalic(FALSE)
.SetFontBold(FALSE)
.SetBorder(FALSE)
.SetSunken(TRUE);

[nicolas]

上面的m_stInfo定义：CLabel m_stInfo;

[cat_dog]

这么长的代码？

[truman_lau]

能不能效果更好点?
重载对ON_CTLCOLOR消息的处理,用pDC->SetBKcolor改变文本框的背景色时,只有有文字输出的地方才有背景色,有谁知道怎样使整个文本框都变色?我在处理SDI的ON_ERASEBKGROUND消息是也遇到了同样的问题?

[chenzhou35]

easy:

在头文件里定义一个CBrush brush;
在该窗口初始化时：
brush.CreateSolidBrush(RGB(255,0,0));
再重载：
HBRUSH CAboutDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

// TODO: Change any attributes of the DC here
if(pWnd->m_hWnd == m_static.m_hWnd )
{
pDC->SetBkColor(RGB(255,0,0));
return (HBRUSH)brush;
}
// TODO: Return a different brush if the default is not desired
return hbr;
}

快！给分。

[tobato]

我看过做得最好得代码是从CStatic派生Class做得。效果很好！

"屁话，我的代码怎么不好使? "?? 你式过了吗？我可是Copy你得代码啊！确实不好

使，我都没有改过，Static得ID都是和你的代码一样得！

[tobato]
