求教：如何用MFC在对话框上画有颜色的线；如何设置窗口上StaticText的颜色？

[puffgeng]

请给出代码示例。
我知道这些问题很简单，我可是刚学MFC哦，你们别笑话我。

在你的staic的父窗口中重载
OnCtlColor()函数
HBRUSH CSelectPathDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

// TODO: Change any attributes of the DC here
if( CTLCOLOR_STATIC == nCtlColor )
{
return m_Brush ;
}
// TODO: Return a different brush if the default is not desired
return hbr;
}
这样就可以了，m_Brush是你生成的刷子，包含了颜色信息

还不如在OnPaint中画线呢！设置画（刷）笔就好了

[puffgeng]

table，你说的太粗了，我还是不明白。

[puffgeng]

panda_w，请你详细说说。

[五行擒拿术]

我说的是显示Static的颜色，
如果你要画线，就用一个CPen来画线吧。。具体怎么做。。。不太好说。。贴代码
这段代码是画一个日历的框框，以前我写的日历控件，全部都是画线画出来的，累。
void CCalendar::DrawLine(CDC *pDC)
{
int i ;
POINT Despt ;

CPen LightPen( PS_SOLID , 1 , DEFAULT_3D_LIGHT_COLOR ) ;
CPen DarkPen( PS_SOLID , 1 , DEFAULT_3D_DARK_COLOR ) ;
CPen MoreLightPen ( PS_SOLID , 1 , DEFAULT_3D_MORE_LIGHT_COLOR ) ;
CPen* pOldPen ;

//now draw the table border line .
// light pen
pOldPen = pDC->SelectObject( &MoreLightPen ) ;

// pDC->MoveTo( m_rcBorder.left , m_rcBorder.top ) ;
// pDC->LineTo( m_rcBorder.right - OFFSET , m_rcBorder.top ) ;

//draw top line , left to right .
pDC->MoveTo( m_rcBorder.left , m_rcTitle.top ) ;
pDC->LineTo( m_rcBorder.right /*- OFFSET*/ , m_rcTitle.top ) ;
//draw left line , top to bottom
pDC->MoveTo( m_rcBorder.left , m_rcBorder.top + m_rcTitle.top ) ;
pDC->LineTo( m_rcBorder.left , m_rcBorder.bottom - OFFSET ) ;
//draw right line , bottom to top
pDC->MoveTo( m_rcBorder.right - OFFSET , m_rcBorder.bottom - OFFSET ) ;
pDC->LineTo( m_rcBorder.right - OFFSET , m_rcBorder.top + m_rcTitle.top ) ;
//draw bottom line , right to left

table，谢谢，我至少给你10分，但刷子的代码我还是不太明白，请再讲细些好吗？

[五行擒拿术]

你可以通过
HBrush m_Brush = ::CreateSolidBrush( RGB( 0 ,0 ,0 ) );
来生成一个刷子，
关于刷子是什么，刷子就是每次Window重绘窗口的时候，都是用刷子来刷新的，然后再画其他东西。。

[puffgeng]

还是不太明白，来个痛快的，有代码吗？

[puffgeng]

画线已经可以了，代码如下：
void CDialogLoginInfo::OnPaint()
{
CPaintDC dc(this); // device context for painting

CPen pen(PS_SOLID,1,RGB(0,0,0));
CPen *pOldPen=dc.SelectObject (&pen);
dc.MoveTo(50,50);
dc.LineTo(200,200);
dc.SelectObject(pOldPen);

// Do not call CDialog::OnPaint() for painting messages
}
感谢table.

[五行擒拿术]

你只要重载你窗口的OnCtlColor()函数
OnCtlColor()函数
HBRUSH CSelectPathDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

// TODO: Change any attributes of the DC here
if( CTLCOLOR_STATIC == nCtlColor )
{
HBrush m_Brush = ::CreateSolidBrush( RGB( 0 ,0 ,0 ) );
return m_Brush ;
}
// TODO: Return a different brush if the default is not desired
return hbr;
}

写成这样就可以了，虽然会有资源泄漏，不过，至少可以设置你Static的颜色，
你通过修改RGB(0,0 ,0)可以改变颜色

[wild_boy]

改变StaticText颜色

1、给对话框定义成员变量
CBrush m_brush;

2、在对话框初始化函数OnInitDialog(...)中增加
m_brush.CreateSolidBrush(RGB(0, 0, 0));

3、重载对话框OnCtlColor,如下：
HBRUSH CTest2Dlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);

if (nCtlColor == CTLCOLOR_STATIC)
{
/* Update BK Color to RED */
pDC->SetBkColor(RGB(255,0,0));

/* Update Text Color to WHITE */
pDC->SetTextColor(RGB(255, 255, 255));

/* return you own brush
hbr = m_brush;
}

// TODO: Return a different brush if the default is not desired
return hbr;
}

太感谢大家了，都成功了，立刻给分！！！！！！！！
