901223-如何更改对话框的背景色? [英] 901223 - how to change background color of a dialog?

问题描述

嗨 要更改对话框的默认背景色，我尝试覆盖它的PreCreateWindow函数:

 BOOL CMyDialog :: PreCreateWindow(CREATESTRUCT& cs)
{
//  TODO:在此处添加您的专用代码和/或调用基类
如果(CDialog :: PreCreateWindow(cs)==否)
返回为假；

CBrush br;
VERIFY(br.CreateSolidBrush(RGB( 251 ， 235 ， 202 ))))；
cs.lpszClass = AfxRegisterWndClass( 0 ，:: LoadCursor(NULL，IDC_ARROW)，br，NULL);

返回 TRUE；
} 

，但看来DoModal不会导致它被调用.
您的建议是什么?

解决方案

用勺子喂答案.

 CngfhnDlg :: CngfhnDlg(CWnd * pParent /*   = NULL */ )
:CDialog(CngfhnDlg :: IDD，pParent)
{
m_hIcon = AfxGetApp()-> LoadIcon(IDR_MAINFRAME);
   m_brush.CreateSolidBrush(RGB( 0 ， 255 ， 0 )); 
}


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

 // 将句柄返回到我们的CBrush对象
 hbr = m_brush;

 返回 hbr;
} 

(除了说它永远看起来都不好，而且可能与Microsoft的UX准则背道而驰)

看看 CWnd :: OnCtlColor [ ^ ].

带有渐变背景和颜色更改进度栏 [ ^ ]是有用的文章.

hi for changing the default background color of a dialog, i tried overriding it PreCreateWindow function:

BOOL CMyDialog::PreCreateWindow(CREATESTRUCT& cs)
{
	// TODO: Add your specialized code here and/or call the base class
	if (CDialog::PreCreateWindow(cs) == FALSE)
		return FALSE;

	CBrush br;
	VERIFY(br.CreateSolidBrush(RGB(251, 235, 202)));
	cs.lpszClass = AfxRegisterWndClass(0, ::LoadCursor(NULL, IDC_ARROW), br, NULL);

	return TRUE;
}

but it seems that DoModal doesn''t cause it to be called.
what''s ur suggestion?

解决方案

spoon feeding the answer.

CngfhnDlg::CngfhnDlg(CWnd* pParent /*=NULL*/)
	: CDialog(CngfhnDlg::IDD, pParent)
{
	m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
	m_brush.CreateSolidBrush(RGB(0, 255, 0));
}


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

 // Return handle to our CBrush object
 hbr = m_brush;

 return hbr;
}

(other than saying that it will never look good and is probably contrary to Microsoft''s UX guideline )

Have a look at CWnd::OnCtlColor[^].

Dialog Box with gradient background and Color changing progress bar[^] is a useful article.
