网上收集的关于static text文字修改颜色和字体的解决办法

第一种办法(应该是最好的办法,可以正对单个控件来修改颜色,也许对其他类型的控件也可通用):

 首先我们在对话框中添加OnCtlColor消息映射函数,函数作用/函数原型/参数解释请看MSDN描述~

QUOTE:

CWnd::OnCtlColor See Also
CWnd Overview | Class Members | Hierarchy Chart | CDC::SetBkColor
The framework calls this member function when a child control is about to be drawn.

afx_msg HBRUSH OnCtlColor(
   CDC* pDC,
   CWnd* pWnd,
   UINT nCtlColor
);
Parameters
pDC
Contains a pointer to the display context for the child window. May be temporary.
pWnd
Contains a pointer to the control asking for the color. May be temporary.
nCtlColor
Contains one of the following values, specifying the type of control:
CTLCOLOR_BTN   Button control
CTLCOLOR_DLG   Dialog box
CTLCOLOR_EDIT   Edit control
CTLCOLOR_LISTBOX   List-box control
CTLCOLOR_MSGBOX   Message box
CTLCOLOR_SCROLLBAR   Scroll-bar control
CTLCOLOR_STATIC   Static control
Return Value
OnCtlColor must return a handle to the brush that is to be used for painting the control background.
然后我们在对话框上放置两个STATIC控件,ID分别为:IDC_STCCOLOR和IDC_STCTWO。然后在对话框的类中添加成员变量(别告诉我你不知道怎么添加……),变量需要两个,每个成员变量对应一个控件~

  ps:变量种类要选择控件变量~这要的控件变量的类型一般是CStatic~

  然后我们在刚才的那个消息映射函数中写下下列代码:

QUOTE:

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

  if (GetDlgItem(IDC_STCCOLOR) == pWnd)
  {
    pDC->SetTextColor(#ff0000);
  }
  else if (GetDlgItem(IDC_STCTWO) == pWnd)  
  {
    pDC->SetTextColor(#0000ff);
  }

  return hbr;
}
这里之所以要先判断句柄,是因为我们要针对某一个控件进行设置。如果你直接使用pDC->SetTextColor来设置,那么MFC会遍历窗体的所有控件,然后把颜色设置成一样。

  至于为什么要添加控件的成员变量,我们可以在对话框的CPP文件中发现这段代码:

QUOTE:

void CMFCDialogDlg::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
DDX_Control(pDX, IDC_STCCOLOR, m_cstcColor);
DDX_Control(pDX, IDC_STCTWO, m_cstcTwo);
}

 

 

第二种办法:

在实际的应用中,可以用WM_CTLCOLOR 消息改变mfc中控件的颜色,比如现在就来改变一个static text孔家的

背景色和字体

1 在对话框的类中添加两个变量:

CBrush m_brush;
CFont m_font;

在OnInitDialog()函数中添加:

// TODO: 在此添加额外的初始化代码
m_font.CreatePointFont(150,"华文行楷");
m_brush.CreateSolidBrush(#00ff00);

2 添加WM_CTLCOLOR 消息响应,添加的方法为:

  在对话框类中声明:afx_msg HBRUSH OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) ;

  在消息映射中添加: ON_WM_CTLCOLOR()

  如:

 BEGIN_MESSAGE_MAP(CtestEnvDlg, CDialog)
     ON_WM_CTLCOLOR()
 //}}AFX_MSG_MAP
 END_MESSAGE_MAP()

 

3 添加响应函数:

HBRUSH CYourDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
   HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
   if(m_yourStatic.m_hWnd == pWnd->m_hWnd)
   {
    pDC->SetBkColor(#00ff00);
    pDC->SelectObject(&m_font);
    return m_brush;
   }
   return hbr;
}

这样就可以改变static text的颜色和字体了
